install

Added in your pubspec.yaml as dev dependency:

dev_dependencies:
  value_listenable_test: any

Examples

Listen the emits of ValueListenable:

 test('valueListenable Matcher', () {
     final counter = ValueNotifier(0);
     expect(counter, emitValues([2, 3, 5]));
     counter.value = 2;
     counter.value = 3;
     counter.value = 5;
   });

Also, you can use the test abstraction called valueListenableTest:

valueListenableTest(
  'Counter emits [1] when update method is called',
  build: () => Counter(),
  act: (notifier) => notifier.update(1),
  expect: () => [1],
);

That`s it!
