The dart revision 1ad11facec401ed51a8bdf79dafd77e955b23082 (rolled in https://github.com/flutter/engine/pull/8459) is causing engine-to-framework roll failure for the following two reasons: 1. analyze error: marked @mustCallSuper but does not invoke the overridden method 2. `flutter build aot` failure for examples/hello_world in build_tests-macos The 1. is likely due to1ad11facecand it easy to fix in the framework. However, the 2. is likely due todbfd00f44dwhich I'm not sure how to fix. TBR: bkonyi
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.
