I got advised to use the SnackbarHost pattern rather than direct use of Toast for incidental error messages (think a download completed or maybe failed for a podcast app). But it doesn't look like using Toast is the way forward. From the Design Principles and Components it doesn't seem like a 1:1 replacement. But talking through there is obviously Alerts/Dialogs, maybe status in Curved Text, and when relevant inline in lists. Wondering if there is guidance of samples of dealing with short notices.
