I want to add a Repeat button. Is it possible to restart flow like this? It seems to work, but Composable is not updated.

val user by viewModel.loadingUser.collectAsState(initial = null)
when {
    user.isSucceeded -> navController.navigate(NavScreen.Home.route)
    user.isError -> ErrorConnect { viewModel.repeat() }
    else -> Splash()
}

Is the

when

block in a composable? Also what is

ErrorConnect

? Can you show more of your code.

@Composable

Why would you annotate a launching function as worker thread?

There are multiple things 1. Your

repeat()

does not restart the

.collectAsState()

, instead it just starts collecting the flow independently. Is there a way you can get a flow of the latest

user

value from your

ServiceUser

? 2. Code with side effects (such as

NavController.navigate()

) should not be in composable function (see [1]). In your case you can simply switch between what is being displayed by the value of user

val user by viewModel.loadingUser.collectAsState(null)
when {
    user.isSuceeded -> TabsHome(...)
    user.isError -> Error()
    null -> Splash()
}

Although I don't see the case here, if you really need to have the different screens as destinations , use

LaunchedEffect()

val user by viewModel.loadingUser.collectAsState(null)
LaunchedEffect(user) {
  ... navigate depending on the value of user ...
}

1. This looks like right. It works.

Hmm. Without a buffer capacity, wouldn't that tryEmit only work when there is a collector?

Is emit better? I'm probably missing something. I did by analogy with LiveData.

Since

RepositoryUser.loadingUser()

finishes, I would probably do this

private val _loadingUser: MutableStateFlow<ResponseResult<ModelUser>> = MutableStateFlow(null)
val loadingUser = _loadingUser.asStateFlow()

init {
    reload()
}

fun reload() {
    repository.loadingUser()
        .onEach { loadingUser.value = it }
        .launchIn(viewModelScope)
}

I don't think MutableStateFlow needs to be made public

just fixed it

@knthmn it's working. THX

That makes no sense to me
