VM, package:vm_service_client and/or package:coverage fail to find source line/column

[yjbanov]

This is happening on Flutter commit flutter/flutter@3fbd140.

When we run tests with coverage, one of the tests fails with the following:

/b/build/slave/Linux/build/flutter/packages/flutter/test/widgets/binding_test.dart
Bad state: Couldn't find line and column for token 3230 in file:///b/build/slave/Linux/build/flutter/packages/flutter/lib/src/widgets/binding.dart.

Potentially relevant issue from when something similar came up last time: dart-lang/tools#437

I'd banged up dart-archive/coverage#216 at the time, but I didn't land it; I suspect because perhaps it didn't solve the issue.

That table is for this file: https://github.com/flutter/flutter/blob/master/packages/flutter/lib/src/widgets/binding.dart

Notice that the first line coincides with a mixin declaration, so it might be mixin-related. @kmillikin
