flutter#188352 worked on the
`3.45-candidate.0` branch:
https://flutter-dashboard.appspot.com/#/build?repo=flutter&branch=flutter-3.45-candidate.0
(so this should fix_ flutter#188075
and unblock the beta release).

This is the same patch but with a mutual exclusivity check.
