* Support real fonts in 'flutter test' Change the order of font_managers to query in font_collection so that dynamic_font_manager fonts will be resolved. Tested with test case in `flutter/flutter` repo: `packages/flutter/test/rendering/localized_fonts_test.dart` Ensured: - A font loaded with FontLoader will be used - The default 'Ahem' font is still loaded by default The test above still cannot be fixed because FontLoader and the underlying mechanisms don't cover Locale-specific font loading and therefore a CJK font-family won't be able to be loaded as needed for that test. Fixes #17700 * Format fixup
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 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.
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.io. For specific information about Flutter's APIs, consider our API reference which can be found at the docs.flutter.io.
