The Flutter project has a number of repositories, some important ones include:

• devtools: the DevTools tooling (performance tools, inspector, debugger).
• flutter: the Flutter framework, engine, and flutter command line tool. Start here.
• flutter-intellij: the IntelliJ plugin for Flutter.
• packages and core-packages: the Dart packages maintained by the Flutter team, such as animations, rfw, camera, and webview_flutter.
• samples: examples of Flutter applications for your enjoyment and edification.
• tests: a repository for you to submit your application's tests to ensure that breaking changes don't affect your application.
• website: the source for our documentation site, https://docs.flutter.dev/.

The Flutter engine was previously located at flutter/engine, but has since been merged into flutter/flutter at the engine/ directory. The engine is the rendering backend, which is ported to each platform we support.
