Flutter widget test - wait Future completion - flutter

Question

I have a widget test in flutter that pumps the widget under test,
and when it opens, performs a background operation (staticWrapper.requestPermission()) which returns a Future and, based on its result, set a state.
The problem is that the test is not waiting this future to complete, test code:
/// When micro permission denied, should show error message.
testWidgets('When micro permission denied, should show error message.',
(WidgetTester tester) async {
when(staticWrapper.requestPermission(Permission.RecordAudio))
.thenAnswer((_) => Future.value(PermissionStatus.denied));
await tester.pumpWidget(widget);
final loginText = find.text(callScreen_microPermissionDenied);
expect(loginText, findsOneWidget);
});
Affected widget code:
void _requestMicroPermission() async {
final result =
await staticWrapper.requestPermission(Permission.RecordAudio);
debugPrint("Microphone permission status: $result");
if (result == PermissionStatus.authorized) {
native.init();
} else {
setState(() {
_loginText = tnsManager.getText(TranslationsManager.callScreen_microPermissionDenied);
});
}
}
The expect() method is called before the setState() call.
Any help?

Finally I solved the issue using WidgetTester#pumpAndSettle():
testWidgets('When micro permission denied, should show error message.',
(WidgetTester tester) async {
when(staticWrapper.requestPermission(Permission.RecordAudio))
.thenAnswer((_) => Future.value(PermissionStatus.denied));
await tester.pumpWidget(widget);
await tester.pump();
final loginText = find.text(callScreen_microPermissionDenied);
expect(loginText, findsOneWidget);
});
