In general, I would expect that getting plugins to compile cleanly in strict mode is going to be pretty messy until the engine is fixed to annotate its protocols. The engine contract has always been to call method on the main thread, and plugins assume (and often need) that, but the annotations aren't in place.

Doing it in the other order in all plugins will probably require a bunch of workarounds.

Code Review

This pull request updates the local_auth_darwin package to version 2.0.5. It removes the @MainActor attribute from the sceneDidBecomeActive and applicationDidBecomeActive methods in LocalAuthPlugin.swift, and updates the CHANGELOG.md and pubspec.yaml files. There are no review comments, and I have no feedback to provide.

I'm sure there's a lot more to do here, I'm currently wack-a-moleing the errors from flutter/flutter#194594 so we can get that fixed asap.

There really weren't that many swift 6 errors though.
