The availability of choices in such a vast number is the reason that makes choosing the right mobile app framework difficult. Talking particularly about Flutter Vs React Native, the choice should be made depending on specific requirements.

The blog is going to discuss in detail about Flutter and React Native. We will try to make the selection easier for you by listing all the pointers of both frameworks.

Flutter vs. React Native: An Insight

The market size for cross-platform will reach $546.7 billion by 2033. Talking specifically about Flutter vs. React Native, both frameworks are expected to grow in popularity among companies looking for cross-platform mobile app development frameworks.

Choosing any platform between Flutter Vs. React seems tough owing to the benefits they offer. The Flutter Vs. React war is intense as both frameworks have great functions to offer. However, choosing anyone will seem easier when you have the knowledge about both of them. We will be defining both frameworks one by one to help you make an informed decision.

The framework you choose plays a crucial role in influencing various aspects of your application, including performance, scalability, maintenance, cost, and the speed of development and deployment. Selecting the right mobile app framework can optimise processes, guarantees a seamless user experience, and minimise overall expenses in the long run.

Conversely, making a poor choice can lead to various development challenges. Therefore, to help you save time, effort and a lot of confusion, let’s together explore the ins and outs of both frameworks for making an informed decision.

Flutter framework: origin architect

Flutter has been written using Dart programming language. As a result, it doesn’t depend upon JavaScript to interact with Native components. Dart, in comparison with other popular languages is easy to learn and has traits similar to Swift and Kotlin. Flutter was created by Google and thus got popularity in no time.

Both cross-platform frameworks for app development differ in their system architect. Flutter uses Skia its own rendering engine. Skia provides low-level APIs used for rendering, text layout and other functions as well.

Flutter has been designed to control every single pixel that users draw on the screen. Flutter is renowned for offering a set of rich UI components known as widgets that match the native user interface. Dart offers a native coding experience that is fast and runs smoothly across devices.

React framework: origin architect

In comparison to Flutter, React uses native Android and iOS UI controls to draw content on the screen. React Native realm can easily interact with native platform controls

As a developer, you create shared logic and UI code within the JavaScript domain, facilitating communication between the two realms through the JavaScript bridge. This open architecture offers great flexibility, enabling the targeting of multiple platforms beyond Android and iOS.

However, in applications requiring frequent UI updates, such as those involving animations, the JavaScript bridge can become a performance bottleneck

In practical terms, this makes Flutter more suitable between Flutter Vs. React Native war for constructing UI-intensive applications that demand smooth animations.

UI rendering

Both Flutter and React Native apps have a native look and feel. But they have diverse ways of appearing native. Flutter apps have widgets while React Native applications use components of Android and iOS to offer the native look and feel.

  • Flutter widgets

Flutter widgets replicate UI components found in Android and iOS. These widgets are developed following the Material Design guidelines on Android and Cupertino design patterns on iOS. As a result, Flutter apps offer the native look and feel without added development efforts.

Flutter offers the freedom to customise existing widgets to suit any preference that users want in high-performance apps. It helps to create apps with user-specific designs.

  • React Native components

React Native uses components already available in Android and iOS. Mobile app developers can directly use these components in their Java code to further customise applications.

Despite numerous differences between Flutter and React Native, both frameworks employ a declarative programming style for constructing user interfaces.

Community support

  • Flutter

Flutter enjoys support from a smaller community as compared to React Native. However, it is increasing in size and growing continually. Flutter packages are catalogued on pub.dev, which serves as the Dart equivalent of NPM.

  • React Native

React Native boasts a longer presence in the development scene and currently boasts a larger community compared to Flutter. The majority of typical challenges encountered in React Native app development have already found solutions on platforms like StackOverflow. Given its integration into the JavaScript ecosystem, assistance is easily accessible for React Native developers.

Given the excellent documentation and supportive communities of both ecosystems, you’ll find ample guidance and assistance when starting with either framework, ensuring you won’t feel lost in your development journey

App development support

  • Flutter

Flutter has well-designed animations to ensure cross-platform mobile app development. It also facilitates the easy implementation of complex animations. When developing large applications, it becomes important to include robust state management solutions. Well-known state management packages like Redux, MobX, and Hooks are accessible for both Flutter and React Native.

  • React Native

React Native comes remarkably close to providing a top-notch native user experience. However, in practical scenarios, performance issues can arise due to the JavaScript bridge, particularly in applications demanding extensive animations or frequent UI updates, unlike Flutter that can easily simplify the development of complex applications.


  • Flutter

Flutter is extraordinary when it comes to testing. There is widget testing when it comes to testing the UI. The test runs really fast providing an option to support integration test as well. With this facility, it gets easier to test the entire suite with the official Flutter tools.

  • React Native

React Native on the other hand, lacks the official support that Flutter enjoys as a cross-platform mobile app development platform. Therefore, for testing, React needs support from third-party tools to ensure error-free testing.

For both app development frameworks, writing test is important when it comes to building robust applications. Both these cross-platform mobile app development frameworks have strong capabilities to write unit tests.

Web Support

  • Flutter web

Flutter’s initial support was in beta but it faced serious challenges on this platform. When developing the Flutter application, Dart code undergoes compilation into HTML, CSS, and JavaScript to enable browser execution. However, the resultant app size often surpasses that of a typical web app. Additionally, Flutter also encounters scrolling performance issues. In order to resolve the issue, the Flutter team uses Web Assembly (WASM).

  • React Native for the web

React Native is inspired by React in different aspects. React Native developers have the option to use React Native for the web in order to port their web applications to the web by sharing the same codebase.

This is an impressive offering as a similar business logic can easily be shared across major platforms (including iOS, Android and web). While Web apps generally lack functions when compared to native SDKs. However, React Native for the web is an excellent option for many to start.
