delayed method Null safety

Future<void> delayed(
  1. Duration duration
)

Delay for duration of time.

In the automated test environment (AutomatedTestWidgetsFlutterBinding, typically used in flutter test), this advances the fake clock for the period and also increases timeout (see addTime).

In the live test environment (LiveTestWidgetsFlutterBinding, typically used for flutter run and for e2e), it is equivalent as Future.delayed.

Implementation

Future<void> delayed(Duration duration);
