Flutter vs React Native: Insights & Features Comparison


Keval Padia

Developing mobile applications has always been an important part of the tech industry. Having multiple platforms at your disposal for developing different apps has been a constant issue for a while now.

There is always a gap between the applications developed as they are made by completely different teams for completely different platforms. This where the idea of creating cross-platform mobile applications came from.

There are several solutions but the most popular one right now is to create compiled apps that offer the closest performance to that of actual native applications. The most powerful options in this field are Google’s Flutter and Facebook’s React Native. Let’s take a look at the strengths and weaknesses of both Flutter app development and React Native app development. Let us do an objective React Native vs Flutter comparison in this article.

About Flutter:

Flutter is a reactive cross-platform mobile development framework. It makes use of the Dart language. Dart and Flutter have been created by Google. Google is using the framework for some of its biggest application. It is constantly pushing the framework towards being the ultimate solution for creating cross-platform apps.

Reactive Programming with Flutter -

If you belong to the Android and Java world, you will know that one of the major motives behind Kotlin is to actually eliminate the null reference. When the data is coming asynchronously, things would go out of control. There is a stream of user clicks. There are many parts of your program that need to respond to the incoming data. This issue will give birth to a paradigm in programming which is known as reactive programming.

Development -

The building block of a Flutter application is a widget, that are actually analogous to components in React Native. Flutter offers a large number of ready-to-use widgets. Most of these implement the material design concepts. There are basically two types of widgets: stateless widgets and stateful widgets. These are similar to class and functional components in React. But Flutter’s widgets are not adaptive. So the platform-specific adaptation has to be done manually.

Flutter also supports the Hot Reload feature. It will allow you to rerun your application with the adjustments that are made while development. This also speeds up development. Flutter is supported on Android Studio and Visual Studio Code.

Ecosystem -

Flutter is catching up with a really good speed. Many core packages for mobile development are available for public use. Currently, there are over 1450 packages available for Flutter.

Performance -

Flutter’s application is compiled using arm C/C++ library. It is similar to machine language and gives a better native performance. App development companies believe that Flutter is superior. But it is hard to judge as there are many factors involved in the performance.

Documentation -

The documentation of Flutter is pretty helpful and very thorough.

About React Native:

React Native is perhaps the renowned world champion of cross-platform mobile development. React Native is a javascript framework built upon the React library, both created by Facebook, and it allows you to ship IOS and Android apps with a single code base. It’s used primarily by Facebook, Instagram, Airbnb, and many others. React Native started out as an internal hackathon project at Facebook back in 2013, and in 2015 it was released to the public.

Development -

React Native makes use of the set of components provided by the react-native library for mobile development. React Native also uses a virtual DOM. But it is not to manipulate a DOM since there isn’t one. it is actually used to communicate with native UI elements.

You can get started with React Native by installing the create-react-native-app package with npm. Then install create-react-native-package and use it to create a new React Native application.

Ecosystem -

React Native also supports hot reload. When it comes to packages, React Native is the best option. It has over 5 times the number of packages available for Flutter. It’s a pretty mature framework now and has much more stability than Flutter.

Documentation -

React Native’s documentation is more user-friendly. The official documentation features guides and popular topics in cross-platform development with React Native.

Performance -

The UI components in React Native are compiled to their native equivalents. The JS runs in a separate thread. It communicates with native modules for any action using a bridge. React Native is much faster and more performant than hybrid alternatives. React Native has outperformed Flutter here. But in several cases Flutter should have the upper hand.


It quite difficult to decide who is the winner here. Both React Native app development and Flutter app development come with their own pros and cons. Flutter is comparatively new in the mobile app development area, while React Native is a more mature platform. Thought React Native is the best, Flutter seems to have a better future.
