title: Can't build angular-dart to js
body: <p>By following Angular-Dart tutorial <a href="https://github.com/angular/angular.dart.tutorial/tree/master/Chapter_07" rel="nofollow">Chapter 07</a> I get:</p>
  
  <pre><code> 'Scope' doesn't implement 'containsValue'.
  </code></pre>
  
  <p>It dosin't build...</p>
  
  <p>For the record I did :</p>
  
  <pre><code>dart -c bin/generator.dart
  </code></pre>
  
  <p>It may have to do with Dart update, but I am not sure. 
  I am using a Windows 7 x64, Dart 1.1.1, Angular-Dart 0.9.4.</p>
