In the screens where we show snackbars, going forward is not possible. The snackbar is shown when there’s an error in the stuff needed in order to go forward.
But again, maybe I shouldn’t be speaking here since we really only use them in a handful of places. If it’s a core part of the app maybe you can’t get away with per-screen implementation
If you do have a global one, I assume what you do is dispatch events into it, and it will internally have to queue them properly so that they don’t hide one another. But then if you send too many, you’ll end up waiting an odd number of time for all of them to come and show one by one.
