Material<->Cupertino switching for clear 1:1 widgets #33830
Description
Breaking this out of #8410.
Based on http://bit.ly/flutter-adaptive-widget-problem, there isn't clear feedback on how we can auto-adapt widgets in a generic sense.
Branching off type 4, simple 1:1 matchings off to this bug for tracking.
