Flutter vs. React Native


Flutter is a UI toolkit used for crafting beautiful, natively compiled applications for mobile, web, and desktop from a single codebase. Flutter is not a programming language but it’s a software development kit (SDK) with prewritten code, consisting of ready-to-use and customizable widgets, as well as libraries, tools, and documentation that together serve to build cross-platform apps.

React Native:

React Native is a framework that enables developers to create exciting mobile applications using their existing JavaScript knowledge. You can use React Native in your existing Android and iOS projects or you can create a whole new app from scratch. React Native lets developer to create truly native apps and doesn’t compromise on users’ experiences.

Release Date:


Was officially released by Google in December 2018. Flutter was first released with a beta version in February 2018.

React Native:

Was introduced by Facebook. React Native started as an internal Facebook project in 2013. React Native was officially released in March 2015.

Programming Language:

Flutter uses Dart programming language which was introduced by Google in 2011 and is rarely used by developers. The syntax of Dart is easy to understand as there is easy and great documentation available for Dart. React Native uses JavaScript. JavaScript is a very popular language in the web community at the moment. So it is widely used.

User Interface (UI):

The Flutter components look a bit different from Native components. Since they only have one codebase, the apps look and behave similarly across iOS and Android, but Material Design and Cupertino widgets provide good support.
React Native components look like pure Native components. For example a button on an iOS device looks just like a native iOS button, and the same on Android devices.

Popularity and Community:

As of May 2021 Flutter is more popular on GitHub with 120k+ stars whereas React Native is not far behind flutter it also has 95k+ stars on GitHub. According to Google Trends on an average 61% of developers are interested in Flutter whereas 81% of developers still preferred React Native for the app development. In addition, React Native was launched in 2015 and flutter in 2018, therefore React Native has a comparatively bigger community and users.


Hot Reload:

Hot reloading is the feature that allows the developer to make instant changes in the backend and reflect the changes in the code right away without even saving the file. Both Flutter and React Native support hot reload feature. It increases the efficiency of Developer.

Coding example of adding button:

React Native:






  accessibilityLabel=”Learn more about this login button”



In Flutter:



           margin: EdgeInsets.all(25), 

              child: FlatButton( 

                child: Text(‘LogIn’, style: TextStyle(fontSize: 20.0),), 

                color: Colors.blueAccent, 

                textColor: Colors.white, 

                onPressed: () {}, 



Top Apps:


  • Xianyu app by Alibaba
  • Hamilton app for Hamilton Musical
  • Google Ads app
  • My BMW
  • Makani


React Native:

  • Instagram
  • Facebook
  • Tesla
  • Skype
  • Facebook ads


From the above discussion I can say Flutter is better in terms of performance, engineering cost, compatibility & app features and further market trends. However Flutter components do not look similar to native components but Flutter provides more customization. If you want your app components to look like native components then Flutter is not recommended.

React Native is also not behind the Flutter in terms of performance. If you want your app components to look like native components then you should go with React Native.
