- Flutter is Google's SDK for crafting beautiful, fast user
- experience 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 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,
- which provides a modern, reactive framework, and a rich
- set of platform, layout and foundation widgets.

- help
- Some debugging ability is maintained—enough to profile your
- apps performance. Profile mode is disabled on the emulator
- and simulator, because their behavior is not representative
- of real performance. Profile mode is similar to release mode,
- with the following differences:
- - Some service extensions, such as the one that enables the
- performance overlay, are enabled.
- - Tracing is enabled, and tools supporting source-level
- debugging (such as DevTools) can connect to the process.
- If this option is left unselected, the global option
- BR2_ENABLE_RUNTIME_DEBUG determines whether to build Flutter
- in release or debug mode.
