Flutter vs React Native – What to Choose?

As mobile hardware is progressing, the demand for mobile apps has started increasing. Software developers were looking for a platform that could make mobile apps fast.

Today we are going to talk about React-Native and Flutter.

Flutter

Flutter is an open source UI (SDK) created by Google. The first version of Flutter was known as codename “Sky”. Flutter framework written in C, C++, and Dart Language. Flutter used to develop mobile app, desktop app and web app. flutter initial release was Alpha(v0.0.6)/May 2017 and now currently stable version of Flutter is (v1.17.0)/May 6 2020. Flutter uses single codebase for Android and iOS platforms.

Features of Flutter

  1. Flutter is for developers that want a faster way to build beautiful apps, or a way to reach more users with a single investment.
  2. Flutter is also for designers that want their original design visions delivered consistently, with high fidelity, to all users. In fact, CodePen now supports Flutter.
  3. Flutter is approachable to programmers familiar with object-oriented concepts (classes, methods, variables, etc) and imperative programming concepts (loops, conditionals, etc).

You can build full-featured apps with Flutter, including camera, geolocation, network, storage, 3rd-party SDKs, and more.

What makes Flutter unique

Flutter is different than most other options for building mobile apps because Flutter uses neither WebView nor the OEM widgets that shipped with the device. Instead, Flutter uses its own high-performance rendering engine to draw widgets.

Flutter is different because it only has a thin layer of C/C++ code. Flutter implements most of its system (compositing, gestures, animation, framework, widgets, etc.) in Dart (a modern, concise, object-oriented language) that developers can easily approach read, change, replace, or remove.

Flutter work with following editors or IDEs

Futter support plugins for Android StudioIntelliJ IDEA, and VS Code.

Flutter come with widgets

Flutter ships with a set of high quality Material Design and Cupertino (iOS-style) widgets, layouts, and themes. Of course, these widgets are only a starting point. Flutter is designed to make it easy to create your own widgets, or customize the existing widgets.

React Native

React Native is an open-source JavaScript framework developed by Facebook in 2015. It is used for developing a real, native mobile application for both Android and iOS platforms. It is a JavaScript framework that builds upon the React library to create mobile apps with a single codebase.

Community
Growing Very Fast
Huge Community
Development
Perfect UI because Flutter does not rely on Native design, Flutter controls every pixel on the screen
Depend on platform oem
Components
Huge list of predefine Widgets
Few
Architecture
Flutter’s components are built-in and compiles ahead of runtime. No Bridge! Means batter performance
React native Communicates the native component using a java Script Bridge
User Interface
Lots of built in widgets and libraries including Material Design and Cupertino widgets.
Does not have many UI Components. It on supports the basics, such as buttons and loading icons.
Best Framework Design
Flutter’s innovative and unique architecture really makes a big difference.
Feels more native-like
Performance
Many developers claim that Flutter has better performance. Does not need bridge draw every pixel on screen using Skia (GUI Enginne)
Using Java Script Bridge with native modules
Documentation
Flutter has nice great documentation
React has also good documentation
Development Speed
Since developing separate native apps for both iOS and Android takes a long time and costs a lot of money, either React Native or Flutter will significantly decrease your time to market.
Hot Reload
Both Framework Have Hot Reloading Feature which save lot of time. Hot reload on update the file that was edited. This mean UI updates but state does not.
Code Reusability
both React Native and Flutter support reusable code. However, not all code is reusable. Every app will have at least a little bit of code that needs to be platform-specific
Testing
Flutter has lots of testing features. You can test individual widget. Flutter provides lots of detailed testing documentation
React Native doesn’t have any official integration testing features, but since it’s a JavaScript Framework, it comes with a few unit test.
Release
Adding App to App Store or Google Play is already painful. Cross platform frameworks should not make it harder. React native’s release process is pretty standard, but it is entirely manual. Automatic deployment requires third-party tools. However, Flutter has official documentation for both Fast lane deployment and iOS/Android Release. Automated release is very nice–and Flutter does it better

Finally: – 

Flutter won the Framework Design and Performance Metrics categories, while React Native won the Developer Support category.

I personally use Flutter I like it. Overall, I think Flutter is easier to use.
