Do you want to develop apps faster? And you want to cut costs by using cross-platform development, but you’re not sure which technology to use? In this article, we compare the leading market players – Flutter and React Native – from the standpoint of app owners to assist you in determining which framework is best suited to your startup web development idea.

Let us first know what are these two?

React Native: A React-based framework for developing native applications. It was developed by Facebook and first made available in March 2015. It uses JavaScript as its programming language, which has excellent native performance.

Flutter: A portable user interface toolkit for creating natively-compiled apps for mobile, web, and desktop* platforms from a single codebase. Google created it, and it was first made available in December 2018. Dart is its programming language, and it has excellent native performance.

React Native vs. Flutter

Points of Comparison:

User Interface (UI)

Flutter apps look just as good on modern operating systems as they do on older ones. Because they share a single codebase, the apps look and behave similarly on iOS and Android – but thanks to Material Design and Cupertino widgets, they can also imitate the platform design. How is that even possible?

Flutter includes two sets of widgets that adhere to specific design languages: Material Design widgets are based on Google’s design language of the same name, while Cupertino widgets are based on Apple’s iOS design. This means that your Flutter app will appear and behave naturally on each platform, mimicking its native components.

Application components have the same appearance as native components (e.g. a button on an iOS device looks just like a native iOS button, and the same on Android). Because React Native uses native components under the hood, you can be confident that your app’s components will be instantly upgraded after any OS UI update.

Having said that, this can cause the app’s UI to break, but it happens very rarely.

Consider using third-party libraries if you want your app to look nearly identical across platforms – as well as on older versions of an operating system (as Flutter does) (like this one). They will allow you to use Material Design components rather than native ones.

Code sharing

With Flutter 2 (announced in March 2021), we can ship native apps to five operating systems: iOS, Android, Windows, macOS, and Linux, as well as web experiences for browsers like Firefox, Chrome, Safari, or Edge. Flutter can even be embedded in automobiles, televisions, and smart home appliances. The most significant announcement in Flutter 2 is production-quality web support. It can be used for the following purposes:

Progressive Web Apps (PWAs), which combine the reach of the web with the capabilities of a desktop app, and Single Page Apps (SPAs), which load once and transmit data to and from internet services.

Existing mobile apps – Flutter apps can now be run on a desktop.

iOS and Android – but there are a few libraries that allow you to write the same code for iOS, Android, web, and Windows10 apps.

You can also extract shared code from mobile, desktop, and web apps to a separate repository, treat it as a separate project and inject it like any other dependency.

This allows a developer to concentrate on writing code for a single platform without having to worry about compatibility with others.

The advantage in the marketplace

For Flutter: >>Rich widgets provide a great look and feel.

>>Popularity and community are rapidly growing;

>>Excellent documentation with strong support from the Flutter team (making it simple to                                begin developing with Flutter);

>>Improving Flutter for Web, allowing for a single codebase to be used across mobile and web platforms

>>Time-to-market length is difficult to beat.


For React Native:   >>Stability (5+ years on the market); React Native is used by many successful and prominent market players;

>>A mature, large community;

>>Technology that is simple to grasp;

>>There are numerous tutorials and libraries available, allowing for quick and easy development.

>>The code can be easily repurposed for both web and desktop app development.

Flutter is attracting an increasing number of businesses. After all, as Google refines its tool, we see monthly improvements in the Flutter SDK. Furthermore, the community is always friendly and enthusiastic. Furthermore, Flutter allows us to create not only mobile apps but also web and desktop apps.

React Native, on the other hand, is currently undergoing a large-scale re-architecture at Facebook. The team is working hard to improve support for both React Native users and the larger community. As a result, the community can now easily suggest changes to the framework’s core functionalities via an RFC process that utilises a dedicated GitHub repo.
