This CP lands PR https://github.com/flutter/flutter/pull/129856 into `stable`. The PR above was part of a engine+framework change that got split in half during the stable cut, so now users are seeing some warnings that they can't act on. (Those warnings were only intended for people who were using our methods manually, rather than using normal flutter tooling). ## Issues Fixes https://github.com/flutter/flutter/issues/133069
