Hey guys, I have a question regarding MutableStateFlow. I have a MutableStateFlow in my repo which is being observed in the ViewModel. However, the ViewModel is not receiving any updates. Here's the StateFlow that I have in my repository

private val _isCacheReady = MutableStateFlow(false)
val isCacheReady = _isCacheReady.asStateFlow()

After filling up the cache, I'm updating the value

_isCacheReady.value = true

And here's the observing code

init {
  lobstersRepository.isCacheReady.onEach {
    _savedPosts.value = lobstersRepository.getAllPostsFromCache()
  }.launchIn(viewModelScope)
}

Hmm, that looks fine. If you add `println`s in

onEach

, do they get printed?

Yeah, so I've tried debugging everything and the

onEach

is called the first time when ViewModel initialises. However,

onEach

is not called again when I set

_isCacheReady.value = true

.

You're sure

_isCacheReady.value

set to true already?

Yep, tried logging the value of

_isCacheReady.value

after updating it.

The first time

onEach

is called, is

it

true? (That's what I meant)

Oh sorry. Yeah it is false. I know MutableStateFlow won't re-emit the same state.

Ah, I've got no idea then.

I’m not sure either, but just to confirm the basics – is the scope getting cancelled early for some reason? Add a

.onCompletion { println("complete: $it") }

before your

launchIn

I don't think it should cancel because it is a viewmodel but I'll definitely check it.
