09/09/2020, 10:43 AMHallo guys, wondering about the pros and cons of doing the following:
Copy code
class Activity(val delegate = ScreenDelegate()): AppCompatActivity(), Screen by delegate {
...methods
}the idea is to create a delegate that activities and fragments can use that encapsulates some general screen behaviour.

For fragments you can install a factory on fragment manager if I recall correctly
Unless you meant that it is always a default parameter and you don’t supply different arg at runtime

i just wanted a reference to the delegate within the class

Generally I’d be careful because most likely it should be responsibility of some other class like presenter or w/e
