Use track-widget-creation transformer included in the sdk. (#9085)

This improves performance as the version in the SDK is able to work more
incrementally and avoids creating an expensive ClassHierarchy.
There is now no measureable performance difference with the option so the
kernel transformer can be enabled by default.

Flutter Engine

Build Status

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.dev. For specific information about Flutter's APIs, consider our API reference which can be found at the docs.flutter.dev.

If you intend to contribute to Flutter, welcome! You are encouraged to start with our contributor guide, which helps onboard new team members.
