Comparison between Flutter and React Native

What is Flutter?

Flutter is Google’s UI toolkit for crafting beautiful, natively compiled applications for mobile, web, and desktop from a single codebase. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.

What is React Native?

React Native lets you create truly native apps and doesn’t compromise on your users’ experience. It provides a core set of platform agnostic native components like View, Text, and Image that map directly to the platform’s native UI building blocks.

Comparison on basis of some important parameters.

  1. Programming language:

The key benefit of using a cross-platform mobile app development technology is the ability to use a single programming language to develop apps for both iOS and Android.

React Native use JavaScript as a programming language

Flutter use Dart as a programming language

As JavaScript is widely used by most web developers, it’s easy to adopt the React Native framework. Dart also has a great feature set but it’s rarely used and less known in the developer community. Considering this, it’s clear that React Native wins the point in the programming language category.

2. Technical Architecture

When choosing a cross-platform mobile app development framework, it’s essential to consider its technical architecture. By knowing the internals of the framework, we can make an informed decision and choose the one that is better for our project.

React Native based on Flux

Flutter based on Skia

Flutter engine has most of the native components in the framework itself and it doesn’t always need a bridge to communicate with the native components. React Native, however, uses the JavaScript bridge to communicate with native modules, which results in poor performance.

3. Installation

React Native -NPM

Flutter - Binary Download from source

The installation method should be straightforward without having too many complicated steps so that it could be easily learned by developers that are just starting with it.

Winner: React Native

Score: Flutter 1 , React Native 2

4. Setup and Project Configuration

The process of setting up the developer machine to use the new framework takes time. It requires lots of configuration of software installations. The technology should have proper documentation to get users up and running.

From the comparison above, it's clear that Flutter offers better documentation and CLI support for setup and configuration.

Winner: Flutter

Score: Flutter 2 , React Native 2

5. UI Component and Development API

React Native have Less Components

Flutter have Rich in Components

Flutter is rich in development APIs and UI components while React Native is too much dependent on third-party libraries.

Winner: Flutter

Score: Flutter 3 , React Native 2

6. Developer Productivity

Developer Productivity Developer productivity is the key to building apps faster.

In this regard, it's very important to be able to focus on app development without any kind of wait or distraction.

Being a mature framework, React Native has great developer support in terms of IDEs and language features. Flutter is fairly new at this point but will catch up very soon as the community around Flutter grows.

Winner: React Native

Score: React Native 3 ,Flutter 3

7. Community Support

The React Native community and resources have grown in size since the framework was launched. Flutter is still fairly new, although community support is growing rapidly.

Winner: React Native

Score: React Native 4 , Flutter 3

8. Testing Support

The React Native community has no official support for integration and UI level testing, while Flutter has great documentation and a rich set of testing features.

Winner: Flutter

Score: React Native 4 , Flutter 4

9. Build & Release Automation

Support Flutter has a great build automation tooling and can be used to deploy apps from the command line. React Native apps lack support for the CLI tools that are officially supported for build automation.

Winner: Flutter

Score: React Native 4 , Flutter 5

10. DevOps and CI/CD Support

Flutter apps are easy and painless to set up on CI/CD services by using its strong CLI tools. React Native doesn’t provide any official instructions for CI/CD practices.

Winner: Flutter

Score: React Native 4 , Flutter 6


Both are Best as per requirement of developer and the company .It up to you which framework you want to learn as we all know android is owned by Google and Flutter a is a framework made by Google.

As per my opinion Learn Flutter
