Global mobile app revenues will rise by more than 365 billion dollars in 2023, predicts Statista. And that’s just the very beginning! Do you have a brilliant Mobile App Development concept for your company? However, you are unsure about which technology to pick. We’re going to contrast Flutter with React Native, two technologies that are extremely well-liked in the developer community. Find out which one best matches your company by reading on.

JavaScript vs. Dart as a programming language

The programming language Dart is used by Flutter to create mobile applications. Dart, created by Google, is regarded as a client-optimized language that ensures quick ARM and 64 Machine Code compilation.

Dart’s benefits for creating mobile apps are as follows:

  • User interfaces that are highly optimized and personalized for each platform (iOS and Android).
  • Rapid changes in code source and reloading.
  • In the development process, an efficient AOT (Ahead-of-Time) compilation approach.

JavaScript serves as the foundation for React Native technology. Nearly 67.8% of developers choose to create mobile apps using this programming language, according to Statista data. JavaScript programming offers a number of advantages, including:

  • A sizable development community exists, and there is a modest learning curve.
  • Since it functions on the client-server side, data validation may be done within the browser itself as opposed to sending it to the server.

Support for testing business mobile app development: Flutter vs. React Native

The well-written documentation that Flutter offers contains helpful details on automated testing procedures and the aforementioned testing categories. To evaluate the performance of your app, Flutter offers three primary testing areas, including:

  1. Multiple widgets, including text, screen layouts, and buttons, are tested using widget testing.
  2. Verifying the correctness of a single method, function, or class is done via unit testing.
  3. The goal of integration testing is to ensure that all widgets and services are compatible with one another.

Like Flutter, React Native provides automated unit and integration testing. The key distinction between them, however, is end-to-end testing (E2E). This method of testing aids developers in determining how an app will operate from a user’s point of view on a certain device. While Flutter’s iOS version hasn’t yet been launched, React Native allows E2E testing on both the Android and iOS platforms.

Development of UI Components and APIs in Flutter and React Native

In order to interact with UIs that need to be rendered, React Native employs JavaScript bridges. Additionally, components of the Objective-C API and Java API are required for rendering on iOS and Android, respectively.

As opposed to React Native, Flutter doesn’t rely on the platform’s APIs. It features a library of widgets that aid in the creation of interactive user interfaces, and all required plugins are gathered in a single toolkit. The canvas constructor that Flutter provides allows it to produce nearly similar user experiences for any mobile device. Your app’s user interfaces will seem different on iOS and Android devices if you use React Native.


In conclusion, both Flutter and React Native are excellent choices for business mobile app development. However, there are some important distinctions between them, such as accessibility and time. You can choose between the framework that suits you the best.
