Flutter is a framework for mobile application development using the Dart programming language. It offers high performance and a wide range of customisable widgets, allowing developers to create attractive and high-quality user interfaces. It supports multiple platforms, including iOS, Android and the web. Another advantage of Flutter is that app development is faster and cheaper, as developers can create cross-platform apps using a single code.

React Native, on the other hand, is a mobile app development framework that uses JavaScript and is known for its ability to create high-performance and scalable mobile apps, also offers a wide range of customisable components and a large developer community that supports and contributes to the continuous improvement of the framework. it supports both iOS and Android platforms.

Some of the advantages of using Flutter instead of React Native are:

• High performance: Uses the Skia rendering engine to render high-quality graphics on the screen, resulting in fast and smooth performance.

• Customisable user interface: Offers a wide range of customisable widgets that allow developers to create attractive, high-quality user interfaces.

• Faster development: Allows developers to create cross-platform mobile applications using a single codebase, reducing development time and cost.

• Cross-platform support: Supports iOS, Android and the web, allowing developers to create apps for multiple platforms using a single code.

• Active documentation and support: Has a large developer community and comprehensive documentation, making it easy to learn and develop.

• Easier testing: Flutter has a built-in testing feature that allows developers to easily test their applications on different devices and platforms.
