OneTime <Value> call

Hi, i'm using arkivanov/Decompose for my desktop app, and i have a question, in android i can use MutableSharedFlow/LiveData instead of Value, and i can observe it, and when i observe i set the lifecyle cycle(create/destroy for example), if i set create/destroy it will as oneTimeLiveData/oneTimeFlow, if start/stop it will viewlifecycle owner, i see in decompose is similar but... lifecycle is access from component and not from compose function(content), so how i can't do it

[arkivanov]

Could you please share some code, how do you observe in Android with create/destroy and start/stop?

Ok, thank you arkivanov, and last sorry for question, how you will show the message wich came from server-backend, use in compose and your/Decompose, and thank you again

Sure no problem! With coroutines you can do it as follows:

interface Main {
    val events: Flow<Event>

    sealed interface Event {
        data class Error(val message: String) : Event
    }
}

@Composable
fun MainContent(main: Main) {
    val snackbarHostState = remember { SnackbarHostState() }

    Scaffold(
        modifier = Modifier.fillMaxSize(),
        scaffoldState = rememberScaffoldState(snackbarHostState = snackbarHostState),
    ) {
        Text(text = "Hello")
    }

    LaunchedEffect(main) {
        main.events.collect {
            when (it) {
                is Main.Event.Error -> snackbarHostState.showSnackbar(it.message)
            }
        }
    }
}
