Thanks! Just tested this out manually (running, debugging) on macOS with a few devices connected and it seems to work great (after patching the version in src/shared/capabilities/flutter.ts)! I filed an issue for expression evaluation (flutter/flutter#79439) but other than that are there any other edge cases that we should be concerned about?

Great! I'm not sure if there may be anything else, but perhaps I think I have integration tests here that do a bunch of things for flutter test (inc. expression eval etc.), so maybe I can get them to run over an integration test too to give some more coverage. I'll fix this branch up and work on the tests and let you know if I find any issues.

I've re-tested this and added a few tests, and all seems good to me. Based on flutter/flutter@9e3eadb, I'm setting the version number to enable this as 2.2.0-10 since that changeset appears to first exist in 2.2.0-10.0.pre.

Awesome!
