"Extract"/reuse common code of presenter

[cwsiteplan]

Hi,

I'm having a presenter that does a calculation of some properties on multiple Events like:

@Composable
fun MyPresenter(
    events: Flow<Event>,
): Model {
    var property1 by remember { mutableStateOf<Float>(...) }
    var property2 by remember { mutableStateOf<Float>(...) }
    var property3 by remember { mutableStateOf<Float>(...) }

    LaunchedEffect(Unit) {
        events.collect { event ->
            when (event) {
                is SomeEvent -> { 
                    //calculate properties1,2,3
                }

                is SomeOtherEvent -> {
                    //doSomething
                    //calculate  properties1,2,3
                }
            }
        }
    }
    
    return Model(property1, property2, property3)
}

How do you deal with re-using code within a presenter?
Is there any alternative than extracting the calculation to a function that wraps the property results in a result class and update properties with the result?

ok, seems a bit of a silly question actually. 🙄

i figured that the calculation return value could be a state property rather than being split up in the individual properties.
