Analyzer doesn't notice when (path) dependencies change

[Hixie]

STEPS TO REPRODUCE

1. mkdir foo
2. cd foo
3. dart create -t package the_library
4. dart create the_program
5. Add this to the_program/pubspec.yaml in the dependencies section:

  the_library:
    path: ../the_library/

6. (cd the_program; dart pub get)
7. (cd the_program; flutter analyze --watch); leave this running in the background
8. Add this to the_library/lib/src/the_library_base.dart in class Awesome:

  bool get isAmazing => true;

9. Replace the_program/lib/the_program.dart with:

import 'package:the_library/the_library.dart';
var x = Awesome().isAmazing;

10. Check the analysis.

EXPECTED RESULTS

There should be one issue:

warning • Publishable packages can't have 'path' dependencies • pubspec.yaml:13:5 • invalid_dependency

ACTUAL RESULTS

  error • The getter 'isAmazing' isn't defined for the type 'Awesome' • lib/the_program.dart:3:19 • undefined_getter
warning • Publishable packages can't have 'path' dependencies • pubspec.yaml:13:5 • invalid_dependency

The error is bogus, because the library being depended on does define isAmazing.

If you restart the analyzer, the bogus error goes away.

IMPACT

This is problematic when developing a package, because any example that relies on the package, which you're probably developing in conjunction with the package, will have to have its analyzer continually restarted.
