Flutter vs React Native for App Development

Programming Language

Flutter uses Dart, a relatively new programming language created by Google. React Native platform uses JavaScript, which has been around for decades.

User Interface

Flutter uses the Skia graphics engine to create UI elements, enabling highly custom designs. React Native uses native UI components, providing a more native look and feel for the app.

Performance

Flutter’s use of a customizable rendering engine, Skia, allows for more control over the app’s performance. React Native supports native code integration to optimize performance by writing platform-specific code in Java or Objective-C.

Architecture

Flutter uses a reactive architecture called Flutter Widgets. React Native, on the other hand, uses a component-based architecture.

Development Time

Flutter’s hot reload feature allows developers to change the code and see the results in real time. React Native’s use of JavaScript makes it easier for developers to build user interfaces quickly.

Flutter or React Native is the most well-known cross-platform for mobile app development in 2023, and their popularity has steadily increased. Regarding cross-platform mobile frameworks, Flutter is preferred by 42% of developers, while React Native is preferred by 38% of developers, according to Statista.
