onGpuTimings method

@override void onGpuTimings(void listener(GpuFrameTimings timings)?)

Sets where each frame's GPU timings go, a frame or two after it was encoded; null stops them. The engine does not call it on a device whose features lack DeviceFeature.gpuTimestamps; a backend without the feature may still answer a caller that asks, with what it can measure and its doc saying what that is (Impeller times each labelled pass from submission to completion, and puts it on the Dart timeline).

Implementation

@override
void onGpuTimings(void Function(GpuFrameTimings timings)? listener) {}
