Google Flutter offers developers a UI toolkit that has some similarities to React Native. Flutter also has a native component and compiles web, mobile, and desktop applications from a single collection of source codes. Relying on existing code, Flutter is also a free and open-source framework for developers. Until this point, the two frameworks might sound similar. However, React Native is based on and only uses JavaScript, while Flutter only has a loose connection to the language. Google Flutter primarily uses a new language called Dart. Other differences between the two involve sourcing the tool itself and the installation process, setup and configuration, UI component and development, and community support.
