I have a list used in a `LazyColumn` and a corresponding add

Question

I have a list used in a `LazyColumn` and a corresponding add function in the viewmodel but no matter what I try the list does not refresh itself basically the same code is used for a search feature which works fine only difference it s not called from a `onClick` but from `onValueChanged`

S. · Answer

Screen ```val decks by viewModel decks collectAsState ``` ViewModel ```private val decks = MutableStateFlow Client userDecks value val decks StateFlow lt List lt Deck gt gt = decks suspend fun addDeck deck NewDeck Client addDeck deck decks value = Client userDecks value suspend fun filterDecks input String decks value = Client userDecks value filter bla bla ```

S. · Answer

also checked with printing ` decks value` and it does contain the added value forcing the list to recompose by switching screens etc also shows the new value

S. · Answer

I m using the StateFlow inside Client for a superordinate side menu that s supposed to always show hence my rather scuffed code there we ll see

Michael Paus · Answer

Probably not directly related to your problem but this line in your ViewModel ```val decks StateFlow lt List lt Deck gt gt = decks``` should more correctly be ```val decks StateFlow lt List lt Deck gt gt = decks asStateFlow ```

S. · Answer

So the issue was indeed the mutable ty again also makes totally sense but shouldn t `asStateFlow ` be the same as writing the type explicitly

Mitchell Syer · Answer

asStateFlow blocks even casts from working If you just write the type explicitly then it can be casted to a MutableStateFlow again
