Code Review:
```fun onRefreshTrackCollection() {
    val job = scope.launch {
        refreshTrackCollection()
    }
    when(job.isCompleted) {
        // show snackbar message
    }
}```
How do I better execute a UI change when a coroutine job is complete?

I would have a StateFlow for isShowingSnackbar (or add it to a data class that holds UI state that is exposed via StateFlow), and have
`if(isShowingSnackbar)`
in my compose code.

I would also set the variable after `refreshTaskCollection()` inside the `launch`  block.

```fun onRefreshTrackCollection() {
    scope.launch {
        refreshTrackCollection()
        isShowingSnackbarFlow.update { true }
    }
}```
