totalSpan property

Duration totalSpan

The timespan between vsync start and raster finish.

To achieve the lowest latency on an X fps display, this should not exceed 1000/X milliseconds. That's about 16ms for 60fps, and 8ms for 120fps.

See also vsyncOverhead, buildDuration and rasterDuration.

Implementation

Duration get totalSpan => _rawDuration(FramePhase.rasterFinish) - _rawDuration(FramePhase.vsyncStart);
