Which is better React Native VS Flutter? There is a larger no of mobile phone users in the world. People use their smartphones for a lot of things like conducting business transactions. A lot of companies know the importance of having a mobile application for their customers and they are also looking to hire mobile developers. For big companies, it might be easy for them to hire development teams for both the iOS and Android platform but it is difficult for many small businesses to hire the whole development team.

React Native:

React Native is a cross-platform mobile development framework, which was developed by a software engineer at Facebook (Jordan Walke ). React Native use popular Javascript library. React Native use React.js and Javascript to build apps for both the Android and iOS platforms.

React Native architecture depends on JS runtime environment architecture which is also known as JavaScript bridge. The JavaScript code is compiled into native code during runtime. React Native uses the flux architecture. React Native uses the JavaScript Bridge in order to communicate with the native modules.


Flutter is an open-source cross-platform, it is a mobile development framework developed by Google. Flutter was announced in 2017 at one of the Google conferences. Flutter helps developers in creating native applications and cross-platform apps with ease.

Flutter uses the Dart framework which has most of the inbuilt components so it is big in size and it does not require the bridge to communicate with the native modules. Dart has many frameworks, like Material Design and Cupertino, etc. which provide all the technologies which are required to develop mobile apps. The Dart framework uses the Skia C++ engine, it has all the protocols, compositions and channels.

React Native VS Flutter :

We can compare React native and Flutterby these points.

  •  Programming language:

React Native Mobile app development is done with Javascript and React. This provides an advantage for web developers because they do not need to learn a new language. It makes things easier for companies as they can easily change some of them to the development with React Native.

On the other hand, Flutter Mobile app development is done with Dart which is a new programming language and not so popular. Dart was created by Google in 2011 in order to fix some of the issues of Javascript then It was then used by Google to develop the Flutter framework.

If you want to develop the app with Flutter it means that you would have to learn Dart, the language which is quite easy to pick up. It is like a mixture of Java and JavaScript.

  • Installation and setup:

In order to set up the development environment for both platforms, the developer requires several steps to complete. The React Native framework can be installed by the use of the npm package manager with a simple one-line statement.

This requires Node.js and the npm package manager previously installed. There are some other device-specific tools that are needed for development, such as the Android SDK and the JDK.

To install the Flutter framework, the developer needs to visit the website to download the zipped folder. This can be extracted into the desired location. Then the developer has to manually add the folder to the PATH variable.

There are also other components, which would need to install just like with React Native. the amount of work required is the same for setting up both platforms. But it is an easier option to set up React Native with Node.js and npm previously installed.

  • Development Time:

React native is preferred by the developers because of its efficiency and it reduced the time frame for the development, it adds to the user interface and takes less time in developing the project.

If we compare between Flutter vs. React Native, Flutter takes more time in development. React Native has ready to use components that make the development process simple and quick, hence it enhances the scope of mobile application development without being bothered.

  • Stability:

Stability is one of the important aspects of many companies that expect a good mobile app. When we compare React Native vs Flutter it is very difficult to differentiate.

Flutter2 offers some impressive features for the developers and react native is a framework that is already established and appreciated for its features and where Flutter is still struggling to make its mark.

  • Customer Base:

React Native is among the most promising mobile app development framework for the developers. The react native framework can carry out the project of any size. Like Facebook, Instagram, Airbnb, Skype, Walmart, etc.

Flutter was launched a few years ago because the framework is new to the market so it will take some time to create a base and be recognized in the market.

  • Documentation & Toolkit:

Documentation processing is very complex and time-consuming for many organizations. Flutter is very good at the process of documentation. Hence as far as documentation and Toolkit is considered Flutter is considered as the best option when compared to the react-native. The documentation which is processed through the react-native is not so organized.

  •  UI components:

React Native has a large amount of UI components which is more than Flutter.

If we reduce the number of third-party libraries of React Native then they would have less than Flutter. React Native depends on third-party libraries which can be problematic in some situations because they sometimes contain bugs and glitches or UI inconsistencies with a specific platform.

Flutter has a lot of useful widgets that come along with the framework and it makes you less dependent on third-party UI libraries.

  • Performance:

Flutter takes an entirely different approach to display apps on the screen. Flutter does not use native components from either platform; Flutter creates its widgets and makes the use of the GPU to render it on the screen. Flutter compiles all Dart code to native ARM code which is run directly by the CPU.

React Native makes use of a Javascript bridge to interpret the UI components to be displayed, which then call Objective-C APIs or Java APIs to display the appropriate iOS or Android component on the screen. This extra layer might make React to Native apps slower.

  • Community support:

Community support is essential for new technologies, It helps new developers learn and provide a solution to problems they might face.

React Native has been adopted by many developers with developers around the world. Big companies like Tesla, Walmart, Bloomberg, and Instagram, etc. have also begun making use of it.

Flutter does not have a large community like React Native because of its recent creation, but it is also adopted by many developers globally. Companies like Alibaba, Tencent, etc. have already begun to use it for app development.

Conclusion: React Native VS Flutter

It is very difficult to determine which the winner is because both have their own pros and cons. But we can say that Flutter will take some more time to get stable in the industry compared to React Native because it is new in the market. Choosing a platform as a developer or a company depends on many things such as your previous stack, company budget, current development team, etc. A company that has a web development team would find it much easier to change some of its developers to React Native. Flutter would be chosen by those companies which are more familiar with languages like Java and C#.
