I have an abstract class where I want two fields two have a default
-value. But you should also be able to override them. Currently I have this:
abstract class Dummy {
// ...
Duration get progressBarAnimationDuration;
Curve get progressBarAnimationCurve;
}
How can I give a default
to these fields and also have the option to override
them if needed?
nothing special about it being an abstract class -
abstract class SuperClass {
Duration get progressBarAnimationDuration => const Duration(seconds: 1);
Curve get progressBarAnimationCurve => Curves.easeInOut;
}
class SubClass implements SuperClass {
@override
Duration get progressBarAnimationDuration => const Duration(seconds: 2);
@override
Curve get progressBarAnimationCurve => Curves.easeIn;
}
