Flutter vs React Native: A Developer’s Perspective

Google’s Flutter and Facebook’s React Native are the two powerful contenders in the dynamic field of cross-platform mobile app development, competing to prove their worth. React Native was said to be the ‘Future of Hybrid Apps’ when Flutter appeared in the market as a newbie. React Native is already a mature tool and has a huge community, but Flutter also started seeing huge adoption rates since 2017. In this post, we will compare each of them from a developer’s perspective.

  1. Programming Language

React Native uses JavaScript while Flutter uses Dart. Web developers using React can build mobile apps with little training since JavaScript is a dynamically typed language. Those using Flutter for app development, can get started with Dart as programming language by following an easy-to-follow documentation.

  • API components and smart features

When compared to Flutter, React Native provides less features and API components.  This framework offers UI rendering as well as different modules. React Native is also useful, but it is completely dependent on third-party modules as well as libraries. Flutter is considered as the winner while comparing react-native Features as well as API.

  • Architecture

React Native architecture relies on the JS runtime environment, it can also be considered as the JavaScript Bridge, and this framework utilizes Flux architecture from Facebook. Flutter comes with Dart framework, so it is always more prominent in size. The Dart framework utilizes the Skia C++ engine. It contains all the essential protocols, channels as well as compositions. Overall, Flutter provides everything needed for hassle-free application development.

  • Development

The number of widgets provided by React Native are less than Flutter’s yet it’s quite inclusive. In the comparison between Flutter vs React Native, Flutter takes more time in development. The ready to use components of React Native makes the development process simple and quick. React Native uses component and a virtual DOM to communicate with native UI elements. Flutter enables you to rerun your application with the adjustments you make while development and speeds up development.

  • Performance

React Native isn’t compiled to C/C++ or a native language, instead, the UI components are compiled to their native equivalents, and the JS runs in a separate thread and communicates with native modules for any action needed through a bridge. So, when it comes to performance, Flutter’s approach is quite different than that of React Native, or even Native Script. Flutter’s application is compiled using arm C/C++ library so that it’s closer to machine language and gives a better native performance.

  • Documentation

React Native’s documentation is good and is user-friendly. It explains what the props are, what they stand for and how to use them. Flutter’s documentation on the other hand is quite helpful and very thorough. It might be a little difficult to read if you have no programming experience, but once you get used to it, you’d find everything you need, written in the documentation.

Both React Native, as well as Flutter comes with their advantages as well as disadvantages.  Flutter is the feature-rich framework. It supports unit testing and widget testing, but Reacts Native is a few units testing as well as functionalities.
