The code itself looks good to me! However, I'm less familiar with the engine side of things and am unsure how testing works. @gaaclarke could you help out with this PR or redirect to someone who might be more appropriate? Thank you!

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 master. 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.
