Methods

collectFromFrameTimings(VmService service, String isolateId, Duration window) → Future<List<FrameData>>

Primary method: collect FrameTiming events from flutter.frame extension stream. Flutter emits pre-computed build+raster+vsync breakdown per frame. Much more accurate than parsing raw timeline events.

debugEventNames(Timeline timeline) → List<String>

debugFrameCounts(Timeline timeline) → Map<String, int>

generateReport(List<FrameData> frames, {int targetFps = 60, bool fromFrameTimings = false}) → String

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

parseFrames(Timeline timeline) → List<FrameData>

Fallback: parse raw timeline — use async phase ('b'/'e') for Dart Frame and sync phase ('B'/'E') for Embedder raster events.

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
