I've one variable (paging data stream) that gets data from view model based on some input id. This data should only arrived when user click on certain button, else data would be empty. How can i make sure that this data comes from view model when user click on button and provide that input id. code is in thread

Tried following, but not working, it change variable value, but not triggering data from view model

var postId by remember { mutableStateOf<Long?>(null) }

val comments =
    remember(commentViewModel) { commentViewModel.getPostComments(postId) }.collectAsLazyPagingItems()

MyFuncion(
    onClick { id ->
        postId = id
    }
)

I’m not sure, but could this be a use case for rememberUpdatedState?

Tried following but no luck

var id by remember { mutableStateOf<Long?>(null) }
var postId = rememberUpdatedState(newValue = id)

val comments =
    remember(commentViewModel) { commentViewModel.getPostComments(postId.value) }.collectAsLazyPagingItems()

MyFuncion(
    onClick { newId->
        id = newId
    }
)
