Without this, developers have to override `onReportTimings` to listen for `FrameTiming`. That can potentially break previous `onReportTimings` listeners if they forget to call the old listener in their new callback. This PR replaces the similar RP in the framework: https://github.com/flutter/flutter/pull/38574 Once this PR landed, we'll have to create another framework PR to use the stream to replace `onReportTimings` usages. Once that's done, we can then propose the breaking change of removing the deprecated `onReportTimings`.
Flutter Engine
Flutter is Google's mobile app SDK for crafting high-quality native interfaces on iOS and Android in record time. 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.
