is this how I would model the state for a list of results?

data class EventsState(
    val events: List<EventComponent> = listOf(),
    val isLoading: Boolean = true,
    val errors: Errors = Errors.None
)

back in my switch case, I have a case for isLoading, another case for events.isNotEmpty() , another for errors.throwable != null and the final else where I’m assuming the events list is empty

the issue is, when I first load up, and while the events list is coming back, I get the empty state

why is that? isLoading starts off as true and the only time it becomes false is when the events come back, I update the state along with the isLoading in 1 go, when is it getting the chance to fall into the else?

eventsState.value =
    eventsState.value.copy(events = it, isLoading = false, errors = Errors.None)

Did you tried if/else as it's a more explicit way to order conditions?

This is a great opportunity for sealed class, in my eye! A friend of mine wrote an article about this a while ago:

Thanks will check

[oday]

yea youre right this is the way to do it

[Ahaisting]

sealed class is probably my favorite kotlin feature… it allows you to write models in a way where invalid state is impossible 🙂

Shame that throughout the codebase there are such examples already but I thought I could do differently

[oday]

so I’ve started doing this, but there’s an issue with copying the state, I don’t get access to copy when it’s a sealed class

[oday]

into the rabbit hole we go

as long as the subclass is a data class, you can still use copy
