Flutter vs React Native: Advantages and disadvantages


Advantages of Flutter


Pros of a Flutter

  • Hot-reloading: Its stateful Hot Reloading feature updates logic instantly without changing the application state.
  • Rich widgets: It offers feature-rich widgets that follow the rules of Material style (Android) and Cupertino (iOS).
  • Seamless integration: There is no need to Re-write code because it easily integrates with Swift or Objective C for iOS apps and Java for android.
  • Quick shipping: It provides fast iteration cycles and reduces build time as testing requires just one codebase.
  • Codesharing: Codes are written and shared by developers across platforms easily and faster, providing exceptional for MVP development.


Cons of a flutter

  • User interface: Animation support and vector graphics have problems in rendering on time.
  • Operating platform: It currently does not allow creating apps for android auto, tvOS, CarPlay, or watchOS.
  • Updates: Cannot push patches and updates immediately into applications.
  • Tools and Plugins: Third party libraries and tools ecosystem is not as vast as React Native though impressive.


Advantages of React Native


Pros of React Native

  • Native rendering (Platform-specific native components): Without HTML or CSS markup, it uses the host platform to render APIs natively.
  • On-par performance with natively-built apps: It renders the markup of an application to mimic reliable UI components and, so far, maintains high performance.
  • Reactive Components & Ecosystem: Third party UI libraries form a rich ecosystem. Moreover stateful components automatically re-render application appearance with each state change.
  • Debugging: It offers accessibility to intelligent debugging tools and error reporting.
  • Hot-reloading: Hot/Live reload allows developers to add new codes directly into a live application and see the changes without the project rebuild.


Cons of React Native

  • User Interface: specific native UI components might not be supported by Native rendering of APIs, making the user interface look a touch off.
  • Tools and Plugins: Third-party libraries that could be used for higher implementation may typically prove to be outdated.
  • Performance: multi-processing and  parallel threading is not supported, which leads to slow performance.
  • Debugging: Chrome debugger can be inconvenient to update and to examine codes and UI components accurately.


Flutter vs React Native

The information given in the table below lets you know the primary difference between Flutter and React Native.


Flutter vs React Native

React Native vs Flutter : Detailed Comparison



Flutter Performance

In a flutter vs react native performance comparison, an application developed using Flutter is a lot more performant in comparison to react Native. It runs faster as there is no need for any javaScript bridges for communication between the native modules of the app, and that saves development time.

The performance check showed that the flutter has set its animation standard at 60 FPS,  and therefore it gives proof to its quick running performance.

As stated, Flutter uses the SKia graphics library, which supports the UI to be redrawn anytime with every update within the application view. No doubt that Flutter will perform proficiently even at 60 FPS.

React Native Performance

React Native has slower performance in comparison to Flutter. It happens because of the JavaScript bridge used in communication between native modules of the application.

The number of frames reported in a simple React Native app for each interval is much higher than that developed using Flutter.

In some cases, the app took more than 16 milliseconds to render the program forming the application stammer. Some third-party libraries like Proguard can be used to improve your application performance that further optimizes bytecodes.

Similarly, components like SLowdog help set performance timers, which may help track performance issues and resolve them.

Learning curve of React Native for developers

Learning React Native is significantly straightforward for people who have designed applications using JavaScript.

But, web development is different from mobile app development, so mobile developers realize it is comparatively tough to learn and implement the framework.

Over time, React Native has free libraries, intensive documents, and tutorials that improve the learning curve over time.

User experience

Flutter’s capability to provide the best user experience

Flutter proposes an expensive user experience with basic tools, elements, and even custom-built widgets. The generational garbage collection feature is also a part of Dart programming language that helps make UI frames for object code that may be provisional.

This feature of Dart allocates objects inside one pointer bump which circumvents UI clutter, junk, and shutter of animation lag during the development process.

React Native’s ability to give the most effective user experience

Android’s Material Design and style design in iOS are being updated day by day, and it’s relevant for React Native to stay up with the constant modifications.

And also, in addition to that, ready-made React Native UI tools such as Shoutem, React Virgin, and ANT design, make it even tougher to create reliable NATIVE designs across platforms.

However, valuable elements like ScrollView fastened header, Modal parts, Activity indicators, Snap carousels, and pagination components significantly improve the UX across multiple platforms.


The community around Flutter

Since 2017, Flutter Launched, its community has gained a bit more traction than React Native.
