Flutter is an open-source mobile application development framework created by Google. It is used to develop applications for Android and iOS, as well as being the primary method of creating applications for Google Fuchsia.
Flutter apps are written in the Dart language and make use of many of the language’s more advanced features.
On Android, and on Windows, macOS and Linux via the semi-official Flutter Desktop Embedding project, Flutter runs in the Dart virtual machine which features a just-in-time execution engine. Due to App Store restrictions on dynamic code execution, Flutter apps use ahead-of-time (AOT) compilation on iOS.
The Flutter framework contains two sets of widgets which conform to specific design languages. Material Design widgets implement Google’s design language of the same name, and Cupertino widgets imitate Apple’s iOS design.
