How To Convert Android App To iOS App?

Few years back, a mobile app development project with one platform was a good strategy but now developing mobile apps on both Android and iOS platforms is the best idea to ensure that the product reaches more target audiences. So if you have an android app then it is perfect to convert your android app to iOS app to stay ahead of your competitors. According to the reports, “iPhone users spend more money on apps than android users”. But conversion of android app to ios is not that much simple as it looks. Here you’ll get to know about how to convert an Android app to ios app.

How To Convert Android App To iOS App?

Convert Android App To iOS App

1. Analysis Of The App Requirements & Functionality-

First of all you must review all the materials of the existing apps. Those materials can be app design, functional specifications and source code. This will help to align the app’s functionality and business logic. There is a need to modify some of the technical elements like content adjustments, push notifications and 3D touch use on iOS. App conversion process divides the project modification in two perspectives: Technical and Business. Hence the best way is to assign two experts such as software programmer and business analysts to perform the gap analysis. This thought allows for preparing the work scope to increase the new application’s potential and performance. Let’s have a look at the checklist of potential deliverables to port an app-

• Market Analysis (optional)
• Work Breakdown Structure is used to organize all project`s elements
• Functional Specification 
• Code Review
• Design Review

2. Modify Design For App Porting-

Layout and user interface should be changed while develop and application from scratch.  One of the most common mistakes is to copy the existing UI rather than adjusting it as required. It can affect the app look, feel or navigation. Let’s have a look at some factors that you should consider when adjusting design for your app conversion.

2.1 Material Vs Flat Design Patterns-

Apple and Google have different design patterns. Hence if you want to convert an Android app to iOS, prioritise the flat design patterns.

2.2 UI Design-

There are various mobile app UI design trends for Android and iOS. You should have knowledge of how to use UI elements like Navigation bar, floating button, main navigation, tab bar segmented control, alert notifications, buttons, icons, UI controls for android and ios both. Before starting the development process, app design should be segmented into assets. If you want to convert Android app to iOS, the app service design should be sliced in 1x *.pdf. Programmers can easily resize it to 2x or 3x if necessary as it is a vector format. 

3. Customize Coding & Architecture Elements-

Besides programming languages, the app uses some libraries and third-party integrations. Hence it is important to check the platform compatibility your ios or android app is ported to with those elements. Otherwise, some alternative tools should be replaced so as to fit functionality. Let’s have a look at the tech stack outlining the elements required after deciding an Android app to iOS conversion.

• Payment Systems: Braintree, Paypal
• Analytics: Flurry, Google Analytics, Fabric, Crashlytics, Mixpanel
• Social networks: Facebook, Twitter, Linkedin and Instagram

Let’s see te list of pitfalls that you should avoid and it could be challenging when you port an Android app to iOS.

• Check the app localization functionality
• Ensure the work with out of the box solutions(ex, animation)
• Check functionality of push notification or in-app purchases
• Create a Google or Apple account beforehand

4. App Testing And Launch-

Proper testing allows you to develop a great working product. App coding and designing, includes a quality assurance when converting an android app to iOS app. Generally it takes 30% of the total development time. The QA developers test applications in terms of code functionality, design interface and navigation. Have look at the test

Here is a list of possible tests conducted during the QA:

• Functional testing
• Security and Access
• Control testing
• Performance and Load testing
• Usability testing
• Validation testing
• User acceptance

Worth noting that to launch the app to the marketplace correctly, you should use common tools, software and devices. They will help you test the specific platform to meet its guidelines. In general, the App Store of Apple has harsh rules when releasing the mobile application.

Approaches To Convert Android App To iOS-

1. Use J2OBJC For Code Porting-

J2ObjC is a tool for code conversion. It is an open-source command-line tool which translates the Java source code to objective C. Your android app has non-UI codes like app logic and data model. J2ObjC supports Java language and run-time aspects. Here are some of the prerequisites for using J2ObjC. Have look at it-

• They need JDK 1.8 or higher
• Mac laptop
• Mac OS X 10.11 or higher
• Xcode 7 or higher

One can download and install J2ObjC by following the instructions in the Google/J2ObjC GitHub repository.

How To Convert Native iOS And Android Apps To React Native?

In 2015, react native was released as an open-source platform. It doesn’t need HTML or CSS. Rather, the react native developers write native code in Java or Objective C. The ease of complexity and scalability that the framework holds is matchless and the app provides improved user experience. But some software development companies still think that the native apps are best for app development. In most of the situations, businessmen are convinced with respect to the technology stack that these organizations support, thinking about their experience. But, they wind up saving more if the prerequisite of the Android and iOS application isn’t at par with the development. Then, which is the way to go?

Here are two ways to develop a highly reliable android and iOS app- 

• Build native app using React native
• Convert existing app to React native

In case you are putting resources into the development of a Native application, you need not spare one more big budget. Here we’ll guide you about how to convert Native android or ios apps to react native. Before digging into it, let’s see the things to consider while converting native android and ios apps into React Native.

Things To Consider While Converting Native Android And iOS Apps Into React Native-

Reducing the number of code to be written is the most efficient way to convert native Android and iOS app into React Native.If there are lots of changes to be made in the extent native Android and iOS app, it will be better idea to develop a new app using React native. But it limits the requirements and the type of the application. Hence, if you are looking to replace Native Android and iOS application into React Native, below are some of the aspects that you should consider:

1. Update Libraries To Latest Versions-

When you develop an app using react native, it is always advisable to switch to the new and advanced technology stacks. Here the tech stack includes frameworks, tools, libraries and databases. If you’re using other version, it is advisable to check for the android version. Lots of features are available to use when you choose latest version of React native, that includes auto-linking, Android migration, lean core, accessibility and so on. If you find any third party app interrupting with the app with build.gradle, you can include post-install script such as-

    // package.json
    {
        "scripts": {
            "bootstrap": "yarn install && yarn run post-install"
            "post-install": "./scripts/postInstall.sh",
        }
    }

Also, it is recommended to include Hermes to enhance the speed of your app.

    project.ext.react = [
        entryFile: "index.android.js",
        enableHermes: true,  // clean and rebuild if changing
    ]

2. Execute Custom Native Modules-

Just making a module file isn’t sufficient. You need to register a module before using a native module. And you need to build another Java class for the creation and registration of this module. After a successful import of file, last step to complete the registration process is to initiate DevicePackage class. To achieve this, you need to edit file by adding the below code-

new DevicePackage() //Add your package here

In the JavaScript file, you can use the module methods through,

NativeModules.<moduleName>. <methodName>

3. Adding Assets To The React Native App-

There are various assets in an application- launcher icons, push notification icons and custom fonts. These components are to improve the user satisfaction rate. And also it is important to make the react native app as user-friendly as possible. IN this way, you can change the appearance of icon of debug app. Also, push notification is important feature of an app when it comes to bringing a user back to the application. Image that you select for push notification logo should have a transparent background for a better view. Apart from this, images, icons and font also play an important role in the great view of the app. Therefore, you can develop functionality for fetching the necessary font from the rich font family.

    val fontTypefaces = HashMap<String, Typeface>()
    fun downloadFonts(fontName: String, font: GoogleFonts) {
        val handlerThread = HandlerThread("fonts")
        handlerThread.start()
        val handler = Handler(handlerThread.looper)
        val builder = QueryBuilder(font.family)
        if(font.italic == 1) {
            builder.italic()
        }
        if(font.weight > 0) {
            builder.weight(font.weight)
        }
        val request = FontRequest(
            "com.google.android.gms.fonts",
            "com.google.android.gms",
            builder.build(),
            R.array.com_google_android_gms_fonts_certs)
        val callback = object : FontsContractCompat.FontRequestCallback() {
            override fun onTypefaceRetrieved(typeface: Typeface) {
            ReactFontManager.getInstance().setTypeface(fontName, typeface.style, typeface)
            fontTypefaces[fontName] = typeface
        }
        override fun onTypefaceRequestFailed(reason: Int) {
        }

        FontsContractCompat
            .requestFont(context, request, callback, handler)
    }

Also, you can load the fonts by using ReactFontManager. You just need to call the font using React Native is a same way as below-

    const styles = {
        proximanovaText: {
            fontFamily: 'Proxima Nova',
        },
    };

4. UI Components-

Best feature of using React native is that programmers can reuse components to fit and develop application.react native uses pixel density to ensure the layout resolution is at standard with Android. This results in, you don’t need to consider the issues associated with the style misalignment between two platforms. Android and iOS have differences with regards to interfaces as well as design standards. Subsequently, you need to follow material design rules to look through the default components.

How To Add React Native To Your Existing Native Android And iOS App?

Best way to approach a React Native app is to start from scratch. Also you can use it when you want to integrate a user flow to the extent native apps. You can simply integrate react native to your existing apps when you know the appropriate components and steps.

Important steps to know before integration-

• Plan dependencies related to the React Native and work on the directory structure
• Build react native components in Javascript
• Install RCTRootView to iOS app and ReactRootView to Android App, that will work as a container for react native
• Start with the react native server and execute the application.
• Validate that your React Native components are functioning as expected.

Know the importance of building app with react native at- Why you should build your app with react native?

Requirements For Integration-

1. Prepare A Directory Structure In Place-

To provide a seamless user experience, you can have a new folder for react native projects. After this, you can copy existing code to ios or android folder.

2. Set Up Javascript Dependencies-

Go to the root directory. Check installation of the yarn package manager. Here you will be building a new package with-

	{
	  "name": "ReactNativeApp",
	  "version": "0.60",
	  "private": true,
	  "scripts": {
		"start": "yarn react-native start"
	  }
	}

Install react native packages and navigate to new packages. Yarn will create a new folder, which will have all the dependencies about Javascript for building a project.

How To Integrate React Native?

1. Maven Configuration-

First step of configuring maven in to add react native and Javascript dependencies to library build.gradle file. When you want to ensure that you are on the appropriate react native version, you can replace plus sign with actual version of it. Check that you add an entry for the Javascript maven directories and react native to ‘allprojects’. You can also cross-check for the final path.

2. Enable Autolinking Of Native Modules –

For autolinking, You need to make an entry to settings.gradle. Then, add that entry to app/build.gradle.

3. Configuration Of Permissions-

Check your internet permission. You can take a look in Android.Manifest.xml. If according to the user flow, you need access to DevSettingActivity, you can add activity to AndroidManifest.xml.

4. ClearText Traffic-

If your android version is over 9, you’ll notice that cleartext traffic is disabled. It will prevent the app from connecting to Metro builder. To allow the allow the connection, you can apply code userCleartextTraffic to AndroidManifest.xml.

5. Integration Of Code-

Integrating code needs programmers to follow particular steps-

• Build an index.js file.
• Include React Native code
• Get permission for development error overlay
• RenderRender JS component

By default, the dev menu will be activated but not in emulators. Subsequently, you need to use ctrl + M to execute JavaScript code for testing.

6. Testing-

Must Know Kotlin Features For Android App Development

 

Along with Java and C++, Kotlin is a programming language for Android. According to Google, more than 50% of professional Android app developers use Kotlin to develop their Android applications. Meaning that, it is one of the most loved programming languages worldwide. Besides, it is also expected that Kotlin may even change how Java is used on the server. 

Means,if you are an android developer or going to develop android app,  you must know the Kotlin programming language for effective apps development. The best advantage of Kotlin is lesser number of lines of code. Along with this, there are many more useful kotlin features that you should know if you are going to develop an android app. Here we’ll discuss those important features but before digging to it, let’s see the benefits of Kotlin over Java.

Benefits Of Kotlin Over Java-

Kotlin is designed by JetBrains to overcome the challenges of Java. And hence, gradually it is replacing Java in ANDROID app development. Here’s a list of benefits of Kotlin over Java.

• Easy To Maintain- The statically typed programming language support a wide range of IDEs, importantly Android Studio.
• Advanced Compiler- Kotlin has a smart compiler. It can detect errors to compile time and perform a check to reduce runtime errors.
• Fail-Safe System- As the code is compact, the chances of error are less. Besides, there are some app crashes and system failures incidents with Kotlin.
• Interoperability With Java- It has tools and frameworks compatible with Java.
• Concise And Clear- Kotlin for android app development is clear, concise and practical. Kotlin extensions are part of Android Jetpack family which helps to optimize android platform APIs, and Jetpack for Kotlin use.

JetBrains has kept its language design clean and made the syntax simple. Besides, it takes very less time to write the code that improves the developer’s productivity.  As an android developer, you should know these Top 7 Kotlin features that make android app faster, easier and error-free.

Must Know Kotlin Features For Android App Development

1. Null Safety In Kotlin-

Each Java developer must have been frustrated by NPE (NullPointerException) at some point in time. Special Null value can be assigned to object reference and NullPointerException, a RuntimeException is thrown when a program tries to use object reference that has null value. Exception can prematurely terminate the program. As Java doesn’t provide any information about the object not created by developer has no null value, during the compilation time it put unnecessary pressure on java developer to keep the program null safe. 

But when you use Kotlin, no need to worry about this. Kotlin has a null-safety feature at the starting age, that is by determining that values will be assigned to the null factor or not. Kotlin’s compiler is powered by null-safe feature which improves run-time Null Point Exceptions encounters.

2. Lazy-Loading Feature-

Faster loading time is one of the most important criteria for any quality app and Kotlin’s lazy loading feature takes care of this. While using Kotlin for android development, this feature will help you to minimize the startup time for the app. It loads the initial content faster to reduce startup to reduce startup time while slowly leading other less necessary elements and contents down the page. Because of this lazy loading feature, android developers who work with Kotlin can just give the priority to the primary resources and keep them in main memory to ensure faster loading while keeping others or secondary resources in secondary memories.

3. Standard Library Functions-

Developers can use standard library functions offered by Kotlin programming language. It eases implementation of higher-order functions with idiomatic patterns like apply, let, use and so on. Also, it has lost of utilities to work with char and string sequences. Its Extension functions provide query operations for sequences and collections. Kotlin’s JDK classes made working convenient with IO, files, and threading.

4. Data Classes In Kotlin-

The need of a class is always argued by programming language designers/makers. Generally, a data class in java contains huge boilerplate code that developers should skip so as to find out the real use of that class. However in Kotlin, Android developers can write the equivalent of the same Java code very simply with less code. So, data classes in Kotlin are known as one of the useful features.

5. String Interpolation-

String interpolation is done through string literals having placeholders that are assessed to achieve a result where placeholders are replaced with corresponding values. Mostly string handling in Java is difficult, that include the use of plus operators, String.format, and StringBuffer. The simple process of String interpolation in Kotlin becomes complex for Java developers.

6. Collections And Streams-

Java developers must have an idea of processing object collections that are important in the Java app development process. This happens because Java objects get translated to various presented elements through this process. Mostly this causes a parallel stream of translated objects which results in slowing down the application. As a modern programming language, Kotlin handles this with immutable collections. Here, rich functional APIs will consequently return as the collections are characterized by the unique functionality..

7. Extension Functions-

Extensions of Kotlin are very useful, this is so because they allow developers to add methods to classes without changing source code. Similar to Scala’s implicit methods, in Kotlin developer can add methods on a per-user basis to classes. For instance, have you tried activity has some methods such as Hidekeyboard()? With extensions, developers can do it like this-

fun Activity.hideKeyboard(): Boolean {
val view = currentFocus
view?.let {
val inputMethodManager = getSystemService(Context.INPUT_METHOD_SERVICE)
as InputMethodManager
return inputMethodManager.hideSoftInputFromWindow(view.windowToken,
InputMethodManager.HIDE_NOT_ALWAYS)
}
return false
}

Truth be told, with Kotlin extensions there is no need to have utility methods or classes, which can improve the readability of your code tremendously.

Features That Kotlin Has But Not Java-

There are some features that Kotlin has but not Java, and so Kotlin is an ideal choice for android app development over Java.

• Primary constructors
• Smart casts
• Data classes
• First-class delegation
• Operator overloading
• Type inference for variable and property types
• Coroutines
• Companion objects
• String templates
• Operator overloading
• Singletons
• Separate interfaces for read-only and mutable collections
• Declaration-site variance & Type projections
• Lambda expressions and inline functions (i.e., performant custom control structures)
• Range expressions
• Extension functions

React Native Android App Vs React Native iOS App

We all are using mobile apps for our day to day work. According to the survey, in 2017, users around the world downloaded almost 197 billion Android apps and over 25 billion ios apps. App development industry has gained momentum in the past few years and has been growing higher since. With the increasing craze for mobile apps, there’s one massive problem that has arisen for app development companies- Finding skilled developers who can develop for Android and iOS. 

If you are looking to develop an app from scratch, for both iOS and android platform, React native is the best solution. React native is a framework that can be used to develop cross platform apps. It is a javascript-based framework created by Facebook to develop apps supported by ios and android platforms. One of the best benefit of using React is reduced development time, reusable code and app components. But there are some differences between the use of React Native for both the platforms. So, here we’ll see the significant differences between React native app development for android and ios. But before digging to it, let’s see the reasons of why react native is gaining momentum.

Why React Native Is Gaining Momentum?

React native allows you to alter the user interface of an app for both android and iOS development. 

1. Open Source Framework-

The framework is open-source in nature. It’s structure is all set to become compatible with macOS and Windows. Rather than rewriting a code from scratch, you can reuse the already existing written code. You can it by using the React Native’s components in the code of the app you developed or reuse the same code. 

2. Quick Development-

Writing a code from scratch and learning to code in java and swift is tough and time-consuming. But react native solves this issue, rather than having expertise in both, you just need to know Javascript. This makes app development quick and easy. 

3. Focus On The UI – 

React native allows you to develop a smooth and simple to navigate user interface in both operating systems at the same time. UI is the reason of its popularity. Prior to this, developers were needed to focus on one type of operating system. React Native resolved this issue and made improvement more comfortable and balanced for the two platforms.

React Native Android App Vs React Native iOS App-

Android and iOS app development significantly differs from one other. These differences arise when you develop your app using React Native. Here are some of the main aspects where the development process differs.

Also know the most common mistakes to avoid in react development at- Most Common Mistakes To Avoid In React Development

1. Tools-

If you are building your React Native app with React Native CLI, you will use different tools for iOS and Android. 

iOS-

You will need an Xcode tool to build iOS apps with React Native. It installs the iOS simulators and all the required tools to build your iOS app. You need a Mac OS to work with Xcode. Meaning that you need a Mac OS if you want to build iOS apps with React Native, or iOS apps in general.

Android-

While building android apps with React Native, you will need a complete different toolset. First of all, you would need to install the Java development Kit (JDK). The tool that is comparable to Xcode for Android is, Android Studio.

Summary:

• Java Development Kit
• Android Studio
• Android SDK and related configuration

If you completely want to do away with them, you have an option of using Expo.

2. Native Elements-

React native has several elements to be used but the results differ according to the platform they are implemented on. For instance, picker component would display a different outcome on an iOS simulator and a different outcome on the android emulator.

3. Designs-

React native provides a cross-platform development due to the shared code and developers expect to build both versions of apps with less efforts. iOS apps are quite minimalist in design, while android is drawn towards the material design principle. When you use shared code in developing, you need to ensure that the app is suitable as per the natural look and feel for both platforms. Multitask panels in iOS have small tabs whereas interchangeable tabs of Android’s multitasking panel are almost of screen size. Hence, developers need to focus on these differences while developing on a shared platform.  

The android include icons with transparent background and shadows whereas, icons of iOS apps are round-cornered squares. Also, there is a difference in navigation patterns for both operating systems. Android’s native navigation-bar has back and refresh buttons whereas in iOS, back button on the top is screen-specific and also works right swipe gesture.

It is necessary to consider all these differences for developers while working on app development through React Native. 

4. Platform-Specific Styles Elements-

When you work on a cross-platform app, it is necessary to consider the difference in styles elements. Styles added using React Native look different in android and iOS because both operating systems might not support that styling. For instance, you’ve added shadow style in your app, it won’t be visible in the Android version because android does not support this styling. Thus, developers should keep in mind the style differences and use the styles that are supported by both operating systems.

5. Linking Libraries-

Do you want to add third-party libraries in the app using React Native? There is a difference between iOS and Android systems is that- you can’t just use the react-native link called “library name” to get the job done. Rather, you have to link third-party libraries manually. Now, this won’t be an easy using React Native. But why? Because you need distinct knowledge about the android and ios coding. To link libraries manually on these systems, you need to use Java and Objective C language. If the library you are using has the required documentation, you probably won’t be needed to do anything manually. But if it doesn’t, you should know this difference between android and iOS systems to develop apps. 

6. Release Process-

Release process is one of the biggest step after mobile app development. Web app’s release are generally a breeze as compared to mobile apps.

Android-

Android apps are released to Google Play store. This release process is easier than iOS. One can automate release activities such as code signing, creating snapshots and so on using tools like Fastlane. It helps to reduce the time spent on manual release.

iOS-

To release the iOS apps, you need to go through the App store. Basically the apple store guidelines to release and review process are contrasted compare to the Android release process. Thoroughly analyse it to get approved by App Store.

Wrap Up-

Starting from the in-app features to design elements to testing tools, development of android and ios mobile app development using React Native differs on various levels. Developers should know the above mentioned differences and accordingly work to avoid bugs during implementation. Lots of popular companies like Uber Eats, Instagram and Airbnb use the shared platform of React native.

These days, people are looking to develop apps more rapidly with less cost and so searching which framework best fits their app idea. Selecting a framework with best features and understandable architecture is not that much easy as it seems. In 2020,  Flutter is a popular framework among the developer community and it offers many pre-configured widgets and modules for native apps. Whereas, NativeScript is a JavaScript-Based framework which offers complete native-like functionality with multi-platform compatibility options. Despite the fact that NativeScript and Flutter are similar in some aspects, they are diverse in terms of system components, architecture, size, cost of development, and so on. You might wonder which framework to choose, so before choosing the best framework, you must know the comparison Flutter Vs NativeScript.

Before digging to the comparison, know the basics of flutter and NativeScript.

Flutter-

It is an open-source framework which functions with a language called Dart(created by google). Generally it is addressed as an enhanced UI toolkit used to build cross-platform applications with a single codebase. It provides accessibility to develop expressive and flexible UI with native performance. Also, it is supported and contributed by Google team and the entire flutter community. This framework is used to build Apps with material design, advanced OS plugins with simple logic, high performance apps with Skia rendering engine, flexible UI with high-level widgets, Reactive applications with vast data integration.

Google Ads, Alibaba, eBay, BMW, Reflectly are some of the popular apps built with Flutter framework.

NativeScript-

It is an open-source framework to build cross-platform apps for iOS and Android using JavaScript. It transpiles programming language to another another, building native apps using Angular, Vue JS and TypeScript. Dissimilar to other frameworks that makes use of Cordova for delivering a WebView-driven application UI, NativeScript has a rendering engine that provides native performance and user experience. It can be used to build real-time apps, music or video streaming apps, geolocation apps, apps with massive server connectivity.

Airbnb Design, MDBootstrap, Portable North Pole (PNP), SAP are some of the popular apps built with Flutter framework.

Flutter Vs NativeScript-

1. Architecture-

Flutter-

It has a layered architecture. Flutter app’s hierarchy starts with a top-level root function or platform-specific widgets. It is followed by basic widgets which interact with rendering layers and platforms. Beyond the rendering layer exists the animation gestures that transfer API calls to the app’s foundation. It is also called Scaffold that is run by a C/C++ engine and a platform-specific embedder. If you want to separate the presentation layer from business logic, you can consider implementing Flutter BLoC. This architecture eases the development of complex applications with small and simple components.

NativeScript-

It follows the MVC or MVVM architectural pattern. And it is widely functions on Modules, CLI, and plugins. It’s structure includes various modules and each of them is responsible to enable certain features. Root module and page module together form an application module comprising CSS style code, actual business logic and XML based UI codes. Because of MVC friendliness it manages module dialogs.

2. Learning Curve-

Flutter-

Flutter is easy to learn, it just needs basic knowledge of native android or iOS development. It’s documentation is easier to understand as compared to React Native. 

NativeScript-

It provides an extensive learning as developers can switch between TypeScript, JavaScript or angular according to the need, feasibility and comfortability. Declarative coding style eases the development for experts and beginners. A thorough understanding of native performance accompanies development experience in Core Modules and design patterns. 

3. Development-

Futter-

Frankly, Flutter is not good to handle complex projects. It is a good solution to build MVP and faster prototypes when you’re destined to experiment with it and cut costs to see your thoughts in reality. You can invest more and take your thought from simple to complex.

NativeScript-

Complex or advanced apps with high performance work smoothly with Nativescript. Full-packaged complex app development needs additional XML and UI support. This framework follows a bundle workflow process which develops optimized and complex apps with tree-shaking mechanisms, that improves the build time. Also, the Hot Module Replacement feature replaces, updates and upgrades modules without restart of existing apps.

4. UI-

Flutter-

It offers a great UI with elements, simplified tools and customized widgets. Generational garbage collection features help to create UI frames for object codes that may be temporary. Dart allocated objects within single pointer bump avoids UI clutter, junk and shutter of animation lag during development process.

NativeScript-

It is the best solution to build enterprise-level business apps. Also you can customize the free, professional-grade UI elements that native offers. It provides improved user experience due to its features that are supported by native functionality and native controls.  NativeScript tests its libraries, templates and UI elements before implementation to achieve the desired user-interface. You can improve user experience by using methods like getFrameByld, classes like Frame, and properties like navigationContext.

5. Size Of Application-

Flutter-

Simple hello world app size was 7.5 MB. With flutter the app size is influenced by Virtual Machine of Dart and C/C++ engine. To avoid size concerts, flutter can contain all codes and assets. Split-debug-info tag reduces the code size.

NativeScript-

Simple app built by using NativeScript is more than 12MB. Self containing multiple APKs in one package with single codebase targets different device configurations and reduces the app size. ABI mechanism of NativeScript allows device to automatically extract machine code and scan for shared library during development. 

6. Testing-

Flutter-

It offers extensive support for automated testing, a large number of testing features to test apps at unit, widget and integration level. Also flutter provides robust documentation to build and release Android and iOS apps on play store and app store resp. 

NativeScript-

Nativescript follows its own QA workflow which improves an app’s default testing capacities. It supports testing tools like Jasmine, Mocha and QUnit by integrating unit testing directly into default CLI. Also the Appium (external provider) can be used for functional testing.
