This pull request was opened against a branch other than main. Since Flutter pull requests should not normally be opened against branches other than main, I have changed the base to main. If this was intended, you may modify the base back to flutter-3.2-candidate.5. See the Release Process for information about how other branches get updated.

Reviewers: Use caution before merging pull requests to branches other than main, unless this is an intentional hotfix/cherrypick.

Once http://go/engine-build?branch=flutter-3.2-candidate.5 goes green, you'll need to manually roll this SHA into the flutter/flutter flutter-3.2-candidate.5 branch
