What are the advantages of Flutter over React Native?

Flutter and React Native are the two frameworks available in the market that can be used to build applications for Android and IOS. They both are cross-platform. Flutter uses dart language as its programming language, whereas React native uses Javascript.

Flutter targets six platforms—Android, iOS, web, desktop, macOS, and Linux Ubuntu. However, React Native only targets three platforms—Android, iOS, and web.

This Answer discusses and briefly explains why Flutter has more considerable advantages over React Native.

Flutter is better than React Native in the following ways:

Better documentation

Documentation is one of the first go-to thoughts when a developer faces a problem. Flutter’s documentation is considered one of the best-structured documentation. Flutter's team of Google spends much time organizing official Flutter docs so that developers do not feel the hassle of visiting it every time they face a problem. It has details about built-in widgets and packages. In contrast, React native documentation does not provide brief answers to the questions. Its documentation is not as impressive as Flutter's.

Easy to set up

It's easy to set up the Flutter environment for development since it supports native platformsPlatforms that allow us to write code for only one platform i.e. android or IOS. These are callled native platform.. To set it up, the developer needs to download Flutter SDK from Flutter’s official website and add it to the operating system path. It downloads all the dependencies and required packages. But on React native, you need to download third-party packages such as npm to complete the set-up, which many developers find bothersome.

Better performance

Nowadays, performance doesn't matter as many powerful devices are available in the market. But not all users have these powerful devices, so developers need to have this in mind while choosing and developing applications cross-platform or native platforms.

Flutter has a Dart language, developed by Google, especially for this framework. Therefore, it compiles a lot quicker than JavaScript, and communicates with native platform in binary and. Dart’s ahead of time Compiles your application at build time. (AOT), allowing it to improve the performance of the applications. In contrast, React Native communicates its programming language with native through bridges, making it a little compromised in performance.

Secondly, Flutter has its UI toolkit in its framework. Therefore, it draws every pixel on the screen, allowing consistent user experiences across all the platforms, whereas React native only renders native elements that are platform specific. So, developers must check UI elements in all platforms before launching it.

Rich built-in library

Everything in Flutter is a widget. The Google team provides Flutter developers with built-in widgets that are more than enough to build and launch a good application. Flutter also has a rich library of packages that helps developers. On the other hand, React native depends on third-party packages and javascript libraries, which take time to download or load their features in the applications.

However, Flutter is comparatively new and still getting monthly updates compared to React Native, which has matured over time. And Google is serious about making it a general framework for building applications for multiple platforms.
