I have a singleLiveEvent that emits from A class based on a result
private val exampleSingleLiveEvent = SingleLiveEvent<Boolean>()
open val show: SingleLiveEvent<Boolean>
get() = exampleSingleLiveEvent
In my viewModel, I have it as following
open val show: SingleLiveEvent<Boolean> get() = A.show
In my composable, I read it as
val show by viewModel.show.observeAsState()
The issue is that the state of the single live event remains true after it is emitted. So every time I enter the compose, I see the value as true. I, however, want it to be true only when the
SingleLiveEvent is emitted, and not always.
What am I missing here?
I tried using SideEffect, LaunchedEffect and DisposableEffect but it did not help.
Unfortunately google doesn’t find better solution then propose to create some function like consumeEvent:
fun consumeSomeSingleEvent() {
exampleSingleLiveEvent = exampleSingleLiveEvent.value = false
}
You should call this function after your single event is emited and perform the logic.
Here is an official documentation from google on how to work with events for now…
