Flutter | A cross-platform mobile app UI framework launched by Google

Flutter is a cross-platform mobile application UI framework launched by Google, designed to quickly build high-quality native user interfaces on iOS and Android. Flutter uses Dart as the development language, creates UI in the form of components (Widgets) based on a modern responsive framework, and uses the same hardware-accelerated Skia 2D graphics engine as Chrome and Android to provide high-performance native running speed.

The features of Flutter are mainly reflected in the following aspects:

Efficient development: Flutter provides a wealth of controls and integrated development tools, supports hot reload, and a new responsive framework, allowing developers to develop quickly. At the same time, Flutter also supports a composable control set, a rich animation library, and a layered and extensible architecture, allowing developers to achieve infectious and flexible interface design.

Cross-platform compatibility: Flutter's goal is to enable developers to deliver high-performance applications that feel natural and smooth on different platforms. It is compatible with differences in scrolling behavior, typography, icons, etc., ensuring a consistent user experience on both iOS and Android platforms.

High-performance operation: Flutter uses a portable GPU-accelerated rendering engine and a high-performance native ARM code runtime to achieve a high-quality user experience across devices and platforms.

Free and open source: Flutter is completely free and open source, and is released in a BSD-style protocol, which means that anyone can freely use, modify and share Flutter. This helps attract a global developer community to contribute to the development of Flutter.

Overall, Flutter is a powerful and flexible cross-platform mobile application development framework designed to help developers quickly build applications with excellent performance, beautiful appearance and consistent user experience.
