FrameTiming class

Time-related performance metrics of a frame.

See Window.onReportTimings for how to get this.

The metrics in debug mode (flutter run without any flags) may be very different from those in profile and release modes due to the debug overhead. Therefore it's recommended to only monitor and analyze performance metrics in profile and release modes.
