Description

Fixes #24703.
Fixes #30641
Fixes #30641

Flutter driver has problems when flutter apps use more than a single isolate. The other isolates don't start, so apps malfunction. This PR fixes the problem by listening for new isolates to become runnable, and automatically starting them.

Related Issues

#24703

Tests

  • Manually tested against an app that requires isolates.
  • Added checks in flutter_driver_test.dart to verify that all isolates have resume() invoked.

@speaking-in-code Can you rebase this to the latest master to fix the analyzer problems?

@dnfield Would you be up for reviewing this one since you're looking at e2e testing?

I suspect you've tried to do a rebase that has gotten git a bit confused.

Can you either open a new PR with just your changes, or fix up the history on this one?

nit: prefer not shadowing parameter names in the enclosing class, which can get confusing. I don't have a great idea for a name here.

This does make me wonder if there are other cases we should be explicitly passing the isolate reference around though.

Is there a reason we're not just setting the outter isoalte to isolateRef.load() here?

Should we be asserting isolate == isolateRef.load() somehow?

Ahh I see, this could be other isolates the application uses that also started paused, right?

Analyzer wants a type annotation on this array.

It looks like the checks are failing here due to a version solving error. Can you try to update your branch with the latest on master?

So upstream linux is actually broken with this version solving problem: #62146. That will have to be fixed first, then this PR rebased to make CI green.

Looks like this is ready to go except for the flutter-build check. Anything I can do to help resolve that?
