pump method
- @override
override
Triggers a frame after duration amount of time.
This makes the framework act as if the application had janked (missed
frames) for duration amount of time, and then received a v-sync signal
to paint the application.
This is a convenience function that just calls TestWidgetsFlutterBinding.pump.
See also LiveTestWidgetsFlutterBindingFramePolicy, which affects how
this method works when the test is run with flutter run.
Implementation
@override
Future<void> pump([
Duration duration,
EnginePhase phase = EnginePhase.sendSemanticsUpdate,
]) {
return TestAsyncUtils.guard<void>(() => binding.pump(duration, phase));
}
