Flutter vs React Native: A Comparison

The current lifestyle of people worldwide enjoying the comfort of access to everything from their phones has given a competitive edge to the mobile apps industry. But the question of what to use to create these apps has been around for a while. Developers often find it difficult to choose between Flutter vs React Native. Both have been created by the current tech giants of the world, Facebook and Google. 

  • As per Statista, 32% of developers used React Native in 2022, whereas 46% used Flutter for development.
  • The high usage of React Native and Flutter is because of their ability to develop cross-platform apps with the same code. This saves cost and time and gets the same convenience as native development. Moreover, it is easier to maintain and update hybrid apps than native applications. 

In this guide, let us learn about the differences between Flutter vs React Native and will also understand what makes them so special. 


is an open-source UI framework developed by Google in 2017 that aims to design cross-platform apps to run on mobile, Windows, macOS, and Linux and on the web. Flutter’s framework is built upon Dart. Many big companies like Alibaba, Philips Hue, Hamilton, etc., choose Flutter for development. Moreover, Google frequently provides updates for Flutter, improving its performance with each update. 

Advantages of using Flutter

  1. Great UI
  2. Has several widgets
  3. Apps are faster
  4. Helps build web apps (Flutter 2)
  5. Well-structured documentation and community
  6. It helps replicate and create the same UI for different devices 

Disadvantages of Flutter

  1. Not native
  2. Apps are larger
  3. Has a limited set of tools

React Native

Facebook developed React Native in 2015. It is an open-source framework that is based on JavaScript. It also provides a similar feature, using the same codebase to create cross-platform apps, thus eliminating the need to compile other technologies for creating mobile apps. Skype, Instagram, Uber Eats, etc., depends upon React Native for development. 

Advantages of using React Native

  1. Uses JavaScript
  2. Can create apps for multiple platforms using a single codebase
  3. Understands the importance of code reusability and promotes it
  4. Growing and active community
  5. Helps in accelerating coding time

Disadvantages of using React Native

  1. Not native
  2. Does not provide innovative, out-of-the-box components
  3. Limited choices
  4. Abandoned libraries and packages
  5. UI can be hampered easily and needs to undergo vigorous UI testing
  6. Larger apps

Differences between Flutter and React Native

React Native and Flutter are amazing choices for developing a cross-platform application. However, when we take on the angle of Flutter vs React Native, they share several differences which make them unique from each other. 

  • One major difference is the programming languages both frameworks use. React Native is based on JavaScript and uses JSX. However, Flutter uses Dart programming language. 
  • The architecture for both frameworks differs. Flutter uses a 2D graphic rendering library, Skia, whereas, React Native uses the Flux architecture, which also requires JavaScript bridging. Here, JavaScript bridging is necessary for React Native to allow JavaScript and Native code to interact with each other. However, there is no programming bridge in Flutter. 
  • Flutter and React Native documentation guides are excellent. However, Flutter shares more organized and structured documentation. React Native documentation is poorly maintained because it depends heavily on third-party libraries. 
  • Installing Flutter requires you to download the binary from GitHub and set up your system’s environment variables. On the other hand, React Native is installed using node package manager (NPM) with one command on your terminal. 
  • Flutter utilizes its developed widgets, whereas React Native incorporates third-party customization components. Therefore, flutter offers more compatibility. Moreover, Flutter development is solely constructed upon Widgets, whereas React Native uses JSX.
  • React Native has better support for 3D, whereas, Flutter does not support 3D.
  • Flutter offers excellent support for Android devices and robust support for iOS devices, including iPhones and iPads, allowing developers to build native-like apps for the iOS ecosystem.
  • React Native also has strong support for Android devices. Since React Native originated from Facebook’s need for iOS development, it supports for iOS devices, including iPhones and iPads.

Flutter vs React Native – Which one to choose?

Which is better, Flutter or React Native? There’s no one-line answer to this question. Either of them could be better, it depends upon the developer’s preferences and the requirements of the project. 

  • Since Flutter uses Dart, it has a higher compiling rate than JavaScript and thus delivers high performance by default. However, Dart is only used by 6.54% of people, according to Statista, which states fewer developers can learn Dart. Moreover, since it is not widely used, it is restricted by several IDEs, providing no support for the language. 
  • Since React Native architecture uses JavaScript bridging, it is one reason which makes it slower than Flutter. Although Flutter is faster, it turns into a huge file size, which is another problem for Flutter developers. 
  • React Native has higher community support because of the ease it provides by incorporating JavaScript. It saved a lot of time for developers’ saving them from learning a whole new language. 
  • If you want to test a React Native app, you use a third-party testing framework such as Detox. However, Flutter is enriched with integrated testing features.
