not compatible with analyzer 10.0.0

Create a new project and try to mock a class with @GenerateNiceMocks(...)

After downgrading analyzer to 9.0.0 it works.

Are you able to provide a minimal reproduction case?

I suspect that this is the same issue with the bug in Flutter dart:ui: it references a not existing setup_hooks.dart, see. flutter/flutter#181008 for the pending fix.

Thanks much!
