reset method

void reset({ bool notifyChange = true, })

Resets the value to the originalValue.

If T is a class with properties, changing the properties directly on the object instead of updating this ActiveType with a new instance of T with the updated values will prevent reset from performing as expected. Tracking the original value is done by reference internally.

Usage

final age = ActiveType<int>(10); //age.value is 10

age(20); //age.value is 20
age(25); //age.value is 25

age.reset(); //age.value is back to 10. Triggers UI rebuild or...

age.reset(notifyChange: false); //age.value is back to 10 but UI does not rebuild

Implementation

void reset({bool notifyChange = true}) {
  final currentValue = _value;
  _value = _originalValue;

  if (notifyChange) {
    activeController.notifyActivities([
      ActiveStateChanged(
        _originalValue,
        currentValue,
        typeName: typeName,
      )
    ]);
  }
}
