I guess the flutter_driver style will remain for a while to achieve E2E style automation, but it could be more flaky than integration tests with hermetic environment, unfortunately. I understand to keep maintain might be hard, but hopefully they also develop (full) e2e automation as well.
(But could it only achieve via accessibility feature on the device under test?)
