Code Review
This pull request addresses a bug in RadioGroup where the single selection check could fail due to timing issues with client registration. The fix defers this check to a post-frame callback, ensuring all client registrations and unregistrations for the frame are processed. This approach aligns with existing patterns in the Flutter framework. The changes are well-tested with new unit tests that cover both the fix and potential regressions. My only suggestion is to add documentation to the new private method to improve maintainability, as per the Flutter style guide.
