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
Functions
-
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.
