FramePhase enum Null safety

Various important time points in the lifetime of a frame.

FrameTiming records a timestamp of each phase for performance analysis.

Constants

buildFinish → const FramePhase

When the UI thread finishes building a frame.

See also FrameTiming.buildDuration.

const FramePhase(2)
buildStart → const FramePhase

When the UI thread starts building a frame.

See also FrameTiming.buildDuration.

const FramePhase(1)
rasterFinish → const FramePhase

When the raster thread finishes rasterizing a frame.

See also FrameTiming.rasterDuration.

const FramePhase(4)
rasterFinishWallTime → const FramePhase

When the raster thread finished rasterizing a frame in wall-time.

This is useful for correlating time raster finish time with the system clock to integrate with other profiling tools.

const FramePhase(5)
rasterStart → const FramePhase

When the raster thread starts rasterizing a frame.

See also FrameTiming.rasterDuration.

const FramePhase(3)
values → const List<FramePhase>

A constant List of the values in this enum, in order of their declaration.

const List<FramePhase>
vsyncStart → const FramePhase

The timestamp of the vsync signal given by the operating system.

See also FrameTiming.vsyncOverhead.

const FramePhase(0)
