Flutter vs. React Native

Android vs IOS

Cross-platform app development is always a tedious task for developers. To build an Android app or iOS app many cross-platforms are available. The main goal of cross-platform is to enable a developer to write single codebase for multiple platforms. Tools such as React native, Flutter, Xamarin, and Kotlin Native cross-platform solutions are available in the marketplace.

Facebook introduced React Native framework back in 2015. React native is a successful framework for building mobile apps. React native is basically Facebook’s mobile UI framework. React native supports the majority of Android & iOS native APIs. React native has paved the way for uniting both Android and iOS platform’s native APIs.

Flutter is a framework developed by Google in 2017. Google developed Flutter to create fast apps that can run on both Android and iOS platform. By introducing Flutter, Google tried to resolve an issue of cross-platform app development. Flutter works on a completely different programming language called Dart. Flutter allows developers to build apps for Android and iOS both while using the exact same code.

React native and Flutter both frameworks are having cut-throat competition as both platforms provide many similar benefits. To identify which platform is better for developers we have compared features of Flutter and React native platform:

Comparison between Flutter and React native platform

flutter vs. react native

1 Documentation

React native framework doesn’t offer specific and organized documentation. Where in Google provides a structured and organized documentation. With detailed information of flutter, developers can easily gain needed insight.

2 User interface

React native doesn’t have UI components library of its own. So developers have to use third-party libraries. While Flutter has its own built-in UI components for UI app development. Every component in Flutter is defined by their own properties. Flutter provides 100% customized widgets. Components and widgets both are similar words. In Flutter, users only have to use the right widgets and pass the right props. Moreover, widgets can also call upon the properties of its parent component. Flutter’s widgets are available in material design for Google and Cupertino for Apple.

3 Appearance

Both React native and Flutter provide an amazing look and feel of an app. Whether its React native based app or Flutter based app both provide an excellent experience to users. Although, Flutter has features to use device’s core functionalities without any third party component.

4 Plugins

React native is backed by huge community. React native has third-party libraries. People use many third party libraries such as - Calendar, Carousel, and Modal. You can integrate your flutter app with Firebase. Moreover, it is very easy to build new plugins for Flutter as per the developer’s need.

5 Community

Though not a long time ago Flutter was introduced, it is gaining an impressive traction in developers’ community. Still, Flutter’s community is not as strong as a community of React native. Developers can find solutions from Flutter’ well-developed documentation in case of any issue faced while developing an app with Flutter. Gradually Flutter’s community is increasing. React native was developed by engineers at Facebook and Instagram. Therefore, a bigger community is available in case if you face any issues while developing an app. If you also want to contribute in the community, go through contributor’s guide and be a part of it. You can also connect with other developers at Stack Overflow and Github.

6 Performance

When it comes to comparing the performance of React native and Flutter - Flutter wins. Flutter is faster in comparison to React native. Flutter also has an advantage of dart language. Apart from that, there is no JavaScript bridge for interaction with native components. Therefore, the speed of development increases. Flutter also supports animations at 60 fps which is a clear sign of flutter’s high performance.

7 JavaScript vs. Dart

Which programming language to choose is a very crucial decision while developing a mobile app. JavaScript is the most popular language for a server and mobile as well.  JavaScript is a widely accepted and adopted language for React native development. In contrast, Dart is the new programming language developed by Google. Dart is extremely easy to write codes in. Though dart is not a very popular language among developers. Dart is a type-safe and expressive language. Dart comes with a low learning curve so learning becomes much easier for React native app developers. Using Flutter will require learning dart. Though dart is somewhat similar to JavaScript language.

8 Configuration and setup

The setup process of Flutter is straightforward compared to React native. Flutter provides automated checkup of system problems. Wherein, React native does not provide automated checkup facility.

9 Tooling

Flutter is still new and in constant developing mode. Therefore, Flutter has not been able to cope up with React native. Because React native offers support in many IDEs & tools. But yes, Flutter has started providing compatibilities with Visual Studio Code, IntelliJ idea, and Android Studio. Moreover, the dart linter, auto format, code analyzer, and debugger have received positive feedback.

10 Industry adoption

React native is used in many mainstream applications such as Skype, Airbnb, Instagram, Walmart, and Tesla. React native is older and popular framework in comparison to Flutter. So Flutter can’t boast about having any mainstream apps in their dashboard. Hamilton app, Google Adwords, and Alibaba are the only brands that Flutter can mention so far. Gradually many businesses are adopting Flutter. Flutter still needs to add more successful apps in order to build an effective portfolio.

11 Lifecycle management

React native is much better at simplifying app lifecycle management & optimization. Well, in the case of Flutter, you can only work with widget inheritance allowing for changeable and non-changeable conditions.

12 Code Structure

In Flutter, dart language doesn’t consist of any separation between templates, styles, and data in the file. So styling becomes messier in dart language. React native considers JavaScript language. It doesn’t have disadvantages such as dart.


Flutter has started providing many benefits to beat React native. We should remember that Flutter is still new in the app development industry. That is why Flutter has not been able to provide anything new which is not achievable through React native. Developers who come from the JavaScript background will not be able to use Flutter due to dart language. Moreover, styling and animation become difficult in Flutter. In comparison to Flutter, React native is having a huge community to support developers.

Basically, both React native and Flutter have their own pros & cons. There is no doubt that both frameworks ensure smooth performance. Just because Flutter is new it doesn’t mean that it should be overlooked. Also, remember that there is no universal cross-platform available. The final decision of choosing a platform whether it’s React native or Flutter is based on developer’s requirement. Right now, React native has taken over the stage as a stable framework. Flutter is gradually moving forward towards gaining popularity in app development industry as it was introduced in 2017.
