| Flutter Engine |
| ============== |
| [](https://cirrus-ci.com/github/flutter/engine) |
| |
| 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. |
| |
| 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. |
| |
| If you are new to Flutter, then you will find more general information |
| on the Flutter project, including tutorials and samples, on our Web |
| site at [Flutter.dev](https://flutter.dev). For specific information |
| about Flutter's APIs, consider our API reference which can be found at |
| the [docs.flutter.dev](https://docs.flutter.dev/). |
