Both Flutter and React Native are smart choices for cross-platform mobile app development frameworks. Each has its unique features and functionalities. Keep reading to have a detailed comparison between Flutter vs. React Native in 2022.

1. Programming Language

React Native uses JavaScript for building cross-platform apps. This simplifies the developer’s job to start their mobile app development journey. Flutter allows developers to use the dart language introduced by Google in 2011. It is based on object-oriented concepts that developers might have less familiar with. However, they are easy to understand, learn and begin the app development process.

2. Configuration and Setup

As compared to React Native, Flutter support a much easier configuration and setup process. Flutter comes with the capability of automated checkups of system-triggered issues, something which React Native loses.

3. Performance

The Flutter-based apps deliver seamless performance as compared to React Native. Flutter allows compiling code faster than JavaScript. Also, it shows animations at 60 fps as a standard. This concludes that All the Flutter apps are by default high performant.

4. Architecture

In React Native, JavaScript acts as a bridge to establish communication between JavaScript and the native language. On the other hand, Flutter does not necessarily need a bridge for communicating with native modules. It is already wrapped with the required components, which include frameworks like Cupertino and Material Design. This makes the Flutter apps more flexible and stable on various platforms as compared to React Native app development.

5. User Interface

React Native taps into native iSO and Android components using custom components. The major benefit is that React Native has lots of ready-made elements to incorporate as building blocks. However, React Native elements can behave differently on individual platforms. Flutter has UI widgets packaged within itself that make it easy to develop native-like apps by eliminating the need for third-party libraries. Besides, Flutter mobile applications deliver consistent performance across all platforms.
