BenchmarkMetric enum - metrics library

Values

prerollFrame → const BenchmarkMetric

The name for the benchmark metric that includes frame-related computations prior to submitting layer and picture operations to the underlying renderer, such as HTML and CanvasKit.

During this phase we compute transforms, clips, and other information needed for rendering.

const BenchmarkMetric('preroll_frame')

applyFrame → const BenchmarkMetric

The name for the benchmark metric that includes submitting layer and picture information to the renderer.

const BenchmarkMetric('apply_frame')

drawFrame → const BenchmarkMetric

The name for the benchmark metric that measures the time spent in PlatformDispatcher's onDrawFrame callback.

const BenchmarkMetric('draw_frame')

flutterFrameTotalTime → const BenchmarkMetric

The name for the benchmark metric that tracks the timespan between vsync start and raster finish for a Flutter frame.

This value corresponds to FrameTiming.totalSpan from the Flutter Engine.

const BenchmarkMetric('flutter_frame.total_time')

flutterFrameBuildTime → const BenchmarkMetric

The name for the benchmark metric that tracks the duration to build the Flutter frame on the Dart UI thread.

This value corresponds to FrameTiming.buildDuration from the Flutter Engine.

const BenchmarkMetric('flutter_frame.build_time')

flutterFrameRasterTime → const BenchmarkMetric

The name for the benchmark metric that tracks the duration to rasterize the Flutter frame on the Dart raster thread.

This value corresponds to FrameTiming.rasterDuration from the Flutter Engine.

const BenchmarkMetric('flutter_frame.raster_time')
