tester/binding_aware_pump library

Properties

isLiveBinding → bool: Whether the current test binding uses real async (e.g. LiveTestWidgetsFlutterBinding, PreviewTestBinding). When true, pump() without a duration should be used so frames render immediately and real async work progresses naturally. When false (AutomatedTestWidgetsFlutterBinding), pump(duration) should be used to advance the fake clock and fire pending timers.
no setter

bindingAwarePump(WidgetTester tester, {Duration interval = const Duration(milliseconds: 100)}) → Future<void>: Pumps the tester in a way that works correctly in both AutomatedTestWidgetsFlutterBinding (fake async) and live/preview bindings (real async).
drainAndRethrowException(WidgetTester tester) → void: Drains any pending exception from tester.takeException and rethrows it. This surfaces stray async errors (e.g. unhandled MissingPluginException) early, preventing them from silently corrupting test state — especially important in PreviewTestBinding where unhandled errors can prematurely complete the test.
pumpForDuration(WidgetTester tester, {required Duration duration, Duration step = const Duration(milliseconds: 100)}) → Future<void>: Pumps for a total duration, advancing time in steps of step.
pumpUntilNotFound(WidgetTester tester, Finder finder, {Duration timeout = const Duration(seconds: 10), Duration step = const Duration(milliseconds: 50)}) → Future<void>: Pumps in a loop until finder is no longer found.
