I use Koin with Jetpack Compose. I have to create a custom scope for one of my ViewModels as it should stay alive as long as the user is logged in.
I tried to do that in my composable, wrapping it in rememberSaveable and creating a custom Saver for that scope, but on every configuration change a new instance of my Scope was created. So I used one of my ViewModels as a holder for that scope. That ViewModel is single, so there is nothing to worry about.

The module:

val MY_MODULE = module {
    scope(named(LOGGED_IN_SCOPE)) {
        scopedOf(::MyViewModel)
    }
}

In the ViewModel, where I handle the scope creation, I have these methods:

private val _loggedInScope: MutableStateFlow<Scope?> = MutableStateFlow(null)
val loggedInScope: StateFlow<Scope?> = _loggedInScope.asStateFlow()

fun createLoggedInScope() {
    if (_loggedInScope.value != null) return

    val koin = KoinPlatformTools.defaultContext().getOrNull() ?: return

    _loggedInScope.update {
        koin.getOrCreateScope(LOGGED_IN_SCOPE_ID, named(LOGGED_IN_SCOPE))
    }
}

fun closeLoggedInScope() {
    _loggedInScope.value?.close()
    _loggedInScope.value = null
}

I collect that flow in one of my composables and when the user logs in, I pass that scope to another composable, where I inject my ViewModel like this:

val myViewModel by loggedInScope.inject<MyViewModel>()

When the user logs out, I call closeLoggedInScope, but the onCleared in MyViewModel is not being triggered. Does it have something to do with Koin’s scopes? Thank you.
