Flutter is a new way to build high-performance, cross-platform mobile apps. Flutter is optimized for today's, and tomorrow's, mobile devices. We are focused on low-latency input and high frame rates on Android and iOS.
See the getting started guide for information about using Flutter.
Dart Core
- dart:async
-
Support for asynchronous programming, with classes such as Future and Stream.
