Flutter vs. React Native | Choose the Best Mobile Framework in 2022

Businesses developing native applications are often torn between Flutter and React Native. These hybrid apps have many positive implications for developers and both these mobile development frameworks have competent tools and features. Yet the question remains, which is the best mobile framework for the new mobile development requirements in 2022? 

In this article, we will learn the answers to this question by looking at the popularity of these frameworks, and the ease at which a user can learn to use them. 

Flutter and React Native are both modern, popular cross-platform mobile app frameworks. React Native was developed by Metaverse (Facebook) in 2015, and Flutter was set up by Google in 2017.. Let’s compare some essential factors and the background of these frameworks to get a better idea as to which framework will work best for you. 

  1. Programming Languages 
  2. Platform Compatibility 
  3. Documentation 
  4. Architecture 
  5. UI Design 
  6. Performance 
  7. Popularity and Community Support 

Programming Languages 

FlutterReact Native
Flutter uses Dart language, which Google developed for client-side development. Dart is a new language in the market. Learning Dart is easy due to its straightforward syntax which is similar to JavaScript, Java, and C. You can also learn more about dart on https://dart.dev/ React Native uses JavaScript, the most popular language globally, developed by Netscape in 1995. JavaScript is a quite old and commonly used language as compared to Dart

Flutter Documentation is better structured and maintained than the React Native documentation. Flutter’s official YouTube channel also launched some video series which are helpful for beginners, like Widget of the Week, Flutter Decode. Even though React Native is not as developed as Flutter, it is considered more user-friendly.


FlutterReact Native
Flutter does not need to connect with a bridge to convert Dart UI elements into native UI elements. Flutter uses Flutter Skia Engine, which renders UI elements instead of converting. Hence, the Flutter performance engine gives a smooth app experience like a native. React Native uses JS-Bridge for converting components into native UI elements, as shown in the architecture.


React Native Architecture
