Flutter vs React Native: A Developer’s Perspective

As more and more people are adapting new technology, the demand for developing and using mobile app also highly increases. But having multiple platforms for developing these apps is such a complex thing to decide on which platform should we use for app development. Nowadays, more competing platforms are Flutter and React Native. React Native is developed by Facebook whereas Flutter is introduced by Google. Flutter and React native are the two main development frameworks which are contending to prove themselves best and that they are the host of the cross-platform mobile app development. Performance mapping is the best way to identify which framework is ideal for mobile app development. Let us see Flutter vs React Native.

Flutter vs React Native-

Flutter VS React Native

1. Programming Language-

Flutter uses Dart. It uses modern features of several languages to code beautiful native apps. There is no separation of templates, style, and data files. Dart is easy-to-use for people who have experience developing an app in OOP languages such as C++ and Java.

React Native uses JavaScript as its programming language.

2. Reusable code-

Flutter allows overwriting the code. If you want to use reusable code then Flutter is the best option for you.

React native allows to reuse the code but it is restricted to some basic components. React Native takes more time to style the platform.

3. Stability and Flexibility-

On account of flexibility, there isn’t any significant difference as both are managed by well – established tech communities. Flutter offers more customized widgets to build attractive experiences.

On the other side, React Native gives uninterrupted user experience via direct communication with the native platforms.

Flutter is still trying to make its position in the market due to the recent release in the market, and React Native is enjoying the first position in the list of cross- platform app development tools in the market.

4. Development time –

Both, React Native and Flutter committed to provide faster time to market of an app. In comparison between React Native and Flutter, Flutter takes more time for development than React Native.

React Native as ready to use components so its development is simple and quick. And hence it gets high priority for mobile app development without bothering the developers. According to developers point of view React Natiev is more efficient.

5. Community-

As Flutter is new in industry there are plentiful tutorials and guidelines available online available.

React Native is popular and old in industry hence gets lot of community and online support. The skilled developers in javascript are came up with the solution to a problem regarding development.

6. Possibility of validating changes-

One of the most important responsibility of developers nowadays is to make changes specifically if developing cross platform app. However it has a sigh of relief that both React Native and Flutter supports ‘Hot Reload’ feature which allows developers to check and validate changes effectively.

7. Documentation and Tooling-

Flutter provides more organized and efficient documentation  than React Native. So flutter eases the job of app developers. So undoubtedly flutter is better than React Native.

Documentation of React Native is disorganized and bulky. It has missed out many things.

Now focusing on the tooling, we can see a tough competition between these two frameworks. Flutter contains a wide range of IDEs and tools that support React Native. It is compatible with Visual Studio Code, Android Studio etc.

8. Performance-

When comparing React native and Flutter on the basis of the performance, Flutter has benefit over the other. Flutter has advantage due to bridging between Dart and JavaScript to connect with native components.

But,the problem with React native is visible distinguishable when app developers are developing hybrid app.

9. Customer Base-

Flutter is launched just a few years ago, it is struggling to go ahead in market race. Presently only few apps are there which are developed by flutter.

No doubt that, React Native is  most promising mobile app development framework for the developers. This framework can carry any size of project,  examples are Facebook, Instagram, Airbnb, Skype, Walmart.

10. Architecture-

Flutter is very new as compared to React Native, and this makes everyone unsure about the best design to execute for your application. There are some architecture that are popular among Flutter community. You can use BLoC architecture which stands Business Logic Component. This architecture is characterized by Google in DartConf2018, and it states that business logic should be present out of the presentation layer and placed in business logic components.

There are two examples for building React Native applications, Flux and Redux. These frameworks are about unidirectional data flow by making your app components as stateless as possible.

11. Unit Testing-

Flutter uses Dart which gives an excellent unit testing framework which can be used and Flutter gives you a good option for testing  the widgets on runtime at unit test speeds.

In case of  React Native, Developers have all JavaScript frameworks for testing at a unit level. But at the point of UI and automation testing, the situation is not as bright. whether, a number of third-party libraries are available, there is no clear picture there.

12. Configuration and Setup-

Setup process of Flutter is more simple and Straightforward. Flutter has a provision of automated checking of system problem. In such cases using flutter command tells you whether Android toolchain has set up correctly, whether the necessary Flutter plugins have been installed and configured correctly or not and which gives the list of connected devices etc., which sometimes react native miss.

React Native installation is annoying and it requires a lot of attention to moving pieces.


You couldn’t conclude between Flutter vs React Native. Both the frameworks have their own plus points in terms of stability,  performance, documentation and other technical conditions as mentioned above.

From this, you can choose Flutter when you want cross-platform, app that requires highly attractive UI, excellent native performance, quicker development.

You can choose React Native, when you need support from native app performance and have to use JavaScript as a developing language.
