Flutter Support for Runtime Compiled Shaders

The flutter team has yet to say that they are committed to ever shipping general runtime shader support. I would love for them to backtrack on that, and in 2023, I'd like for them to give us general compile-time shader support. The impeller engine is an experimental PR into 3D graphics; it's unclear why the team is prototyping this or what they intend to do with it. But there was some initial feedback from users who were excited about its potential.
