Has anyone here used the new Jetpack DataStore yet? I want to restore the checked state of a checkbox options menu item when a fragment is created.
1. I use `first()` because I only need to set the value from DataStore once, afterwards just clicking the checkbox will check/uncheck it. Does this make sense? Are there any situations where it will break?
2. Is the asynchronicity a problem? As far as I understand, you can't read from DataSore synchronously so this is the only option I can see.
```override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
    
    [...]
    
    viewLifecycleOwner.lifecycleScope.launch {
        menu.findItem(R.id.action_hide_completed_tasks).isChecked =
            viewModel.preferencesFlow.first().hideCompleted
    }
}```


You can also update the menu when the flow gives a new value.

Using collect, collectLatest or onEach + launchIn and update the menu with any changes
