Hello everyone, I've a problem with my flow getting stuck in viewmodel init block. The flow is declared inside dataStoreRepository class, which actually successfully emit's desired value. But after collecting flow, it doesn't proceed inside the coroutineScope. Shared the code in thread:

here is to logcat after process death:

Here is the code:

val suIdKeyFlow = dataStore.data.map { // this is dataStoreRepository class member
    it[PreferenceKeys.suIdKey] ?: 0
}

ViewModel member function:

private suspend fun readSuId(){
    storeRepository.suIdKeyFlow.collect {
        currentUserSuId.value = it
        Log.d("main", "current user su id flow: ${currentUserSuId.value}") // log is printed to logcat
    }
}

ViewModel init block:

init {
    Log.d("main","Main View Model created")// this gets printed to logcat

    viewModelScope.launch(<http://Dispatchers.IO|Dispatchers.IO>){
        Log.d("main","inside viewmodel coroutine scope 1")// this also gets printed to logcat
        readSuId()
        Log.d("main","inside viewmodel coroutine scope 2: --> ${currentUserSuId.value}}")// can't observe this log at logcat

        if(currentUserSuId.value != 0){
            getCurrentUser(currentUserSuId.value)
        }
    }
 isUserLoggedIn()// this sets isLoggedIn mutableState<Boolean> in viewmodel, and observed at composable for automatic login, not necessarily related to problem
        Log.d("main", "  user logged in : ${userLoggedIn.value}")

Collect blocks until the flow closes

@Tim Oltjenbruns Thanks. Seems like I need to practice flows again.

I’ve made the same mistake before. 🙂
