added in: 1.9.0

warning

🛠

Warns when an async callback is passed to FakeAsync.

FakeAsync implementation does not await an async callback and the test will pass even if it should not.

Example

❌ Bad:

void main() {
  // LINT
  FakeAsync().run((fakeAsync) async {
    ...
  });

  // LINT
  fakeAsync((fakeAsync) async {
    ...
  });
}

✅ Good:

void main() {
  FakeAsync().run((fakeAsync) {});

  fakeAsync((fakeAsync) {});
}
