# Flutter Engine

[![Flutter CI Status](https://flutter-dashboard.appspot.com/api/public/build-status-badge?repo=engine)](https://flutter-dashboard.appspot.com/#/build?repo=engine)

Flutter is Google's SDK for crafting beautiful, fast user experiences for
mobile, web, and desktop from a single codebase. Flutter works with existing
code, is used by developers and organizations around the world, and is free
and open source.

The Flutter Engine is a portable runtime for hosting
[Flutter](https://flutter.dev) applications. It implements Flutter's core
libraries, including animation and graphics, file and network I/O,
accessibility support, plugin architecture, and a Dart runtime and compile
toolchain. Most developers will interact with Flutter via the [Flutter
Framework](https://github.com/flutter/flutter), which provides a modern,
reactive framework, and a rich set of platform, layout and foundation widgets.
