VSCode Extension fails to re-analyze when changing branches

When switching between branches where files are moved between directories, VSCode Dart extension fails to recognize the change and shows errors, necessitating reloading VSCode.

Steps to reproduce

1. Create a new git repository
2. Add foo.dart

class Foo {}

1. Add bar.dart

import 'foo.dart';
class Bar {
  Foo foo;
}

1. Commit changes to master
2. Create develop branch off of master
3. Move ./foo.dart to ./foo/foo.dart and update import path in bar.dart
4. Commit changes to develop
5. Checkout master branch

A fix has been made in https://github.com/dart-lang/watcher/issues/83 that fixes some file watcher events being lost when a modified folder is a prefix of a file. I’ll ping you once the fix is available in an SDK so you can test if it solves this for you (I’m not having much look reproducing it now, even without the fix).

If I’m reading the hashes correctly, I think this change is in the Flutter master channel now, so if you’re using that (and have pulled latest) I think you’ll have the fix.

If you’re still able to produce these sorts of errors with that code, do post back (or file a new issue with repro). Thanks!
