Flutter vs. React Native – which is the best choice for 2021?

There are various options for app development. For example, you can use the framework of React Native but also of Flutter. In this blog, we compare React Native vs. Flutter and explain why we choose React Native for App Development Company.

React Native was acquired by Facebook and has to continue open-source available since 2015. It is now an adult and stable tool. Google published the beta version of Flutter in February 2018. Since then, the community has been increasing but still limited. That is an institution, but what is required when comparing React Native vs. Flutter?

React Native and Flutter differ in terms of programming language, how native elements are accessible, the documentation, the testing opportunities, and how the export to IOS & Android. Let’s take a more intimate look at those elements.

Programming language

React Native utilizes JavaScript, a widely-used programming language. Furthermore, React Native uses, as the name suggests, the framework React. Because this is the various used web development framework, the step to React Native will be small for several developers. There are additionally plenty of tutorials, and it is comfortable to reuse code.

Flutter, on the other hand, operates with the Dart language launched by Google in 2011. This relatively new programming language is hardly utilized. Object-oriented theories make the language easy to learn for developers familiar with Java, PHP, or C #. However, as the complexity of the app’s improvements, it is necessary to know more regarding Dart. Also, Dart is supported by approximately a few IDEs & text editors.


React Native has a large community. Many developers have struggled with it, and several players in the market use React Native, such as Instagram, Facebook, and Skype. The association shares a lot of information via GitHub and meetings. This significant association has the benefit that as an app partner, you can quickly find a developer and that as a developer, you can quickly find information. Therefore, the framework is also fully battle-tested, and you can obtain a solution for virtually every bug on the internet.

Flutter’s community has been developing several times now, but not very big yet to solve everyday difficulties. That means that it is more challenging to find developers with a lot of experience with this framework, and it is also numerous challenging to find comfort in the population. There are, however, meatus and other effects. Another disadvantage of a small population is that there are comparatively few extensions and plugins available. After all, developers of extensions and plugins are more likely to work with generally used frameworks.

How do you get native components?

Those APIs allow React Native to reach native modules. Fortunately, Native App has been possible for quite some time, delivering most APIs stable. Also, running with the native components suggests that the apps designed with React Native conform to the standards of the various operating systems (iOS / Android).

Flutter is widget-based. Rather than native elements, Flutter works with a canvas-based rendering engine. Each widget is providing with a canvas on which the device can express itself. That is assembled into a scene which is then displaying as a pixel matrix. The generator is a complete Software Development Kit with UI rendering, APIs, navigation, testing abilities, and lots of buildings. There are also widgets for Material Design. For example, Flutter has everything it takes to get started with Flutter App Development Company in USA.


For questions regarding Native Application, you can often contact the community, for example, via GitHub. Flutter has this more minor, but on the other hand; Google does give excellent documentation in the form of a getting-started design. There is also good documentation of performing live and CI / CD support.

The CLI tool Flutter also guides you through the service and the CI / CD system Code Magic. Since 2019, however, React Native also has a Command that can help with troubleshooting and automatically fixing errors. Furthermore, extensive documentation is also possible for this framework.

To test

React Native uses third-party tools and APIs for measuring to make this potential, while Flutter has built-in measurement tools. JavaScript has few unit testing frameworks, so React Native needs third-party tools like Appium or Detox.

On the other hand, Flutter has built-in abilities for testing units and widgets, and integrations. Documentation is also available regarding the testing opportunities.

And how does it work?

After you have improved your app, it needs, of course, to be pushed to iOS and Android. React Native appropriates the JavaScript Bridge API for this. This ‘maps’ the JavaScript code to native code. The Bridge is called with a particular function and assures that it is delivered to the corresponding purposes on Android and iOS without a collection step. 

React Native vs. Flutter?

React Native Quick start is regularly quick to get excited and has a large population to fall back on. That is helpful if you are looking for a new developer and have problems as a developer. The framework is stable, for example, in terms of APIs. It is experienced and strong and is used by many major players.

Flutter has advantages in terms of documentation and the canvas rendering engine and testing capabilities, but that does not exceed the disadvantages of using Dart and the small community. For now, there are still too many restrictions to make flutter an excellent alternative to Native App Development.
