TestDriverDefaultFutureValue<T> class

Use this annotation on properties/methods which return Futures in your Driver to generate the hardcoded default test values which will be used by the TestDriver. Your DrivableWidget will then use these values from the TestDriver when it is created during testing.

Here is an example of how to use these:

@GenerateTestDriver()
class RandomNumberWidgetDriver extends WidgetDriver {
    RandomNumberService _randomNumberService = ...;

    @TestDriverDefaultFutureValue(123)
    Future<int> get randomNumber => _randomNumberService.theRandomNumberFuture;

    @TestDriverDefaultFutureValue(false)
    Future<bool> updateRandomNumber() {
        ...
    }
}

This will generate the following TestDriver

class _$RandomNumberWidgetDriver extends TestDriver implements CoffeeLibraryPageDriver {
    @override
    Future<int> get randomNumber => Future.value(123);

    @override
    Future<bool> updateRandomNumber() {
        return Future.value(false);
    }
}
