Use case

Material 3 FAB button spec states additional color mappings. https://m3.material.io/components/floating-action-button/specs#4a69fc37-5201-4ebe-9ce4-3b6273691dfb

Proposal

It would be really nice if we had access to those additional mappings from the API. Currently, AFAIK, only primary FAB is mapped here https://github.com/flutter/flutter/blob/bfd92a86197a289fdccaad85c9179ea73f049734/dev/tools/gen_defaults/data/fab_primary.json
