title: Polymer-dart: http://www.xxx/index.bootstrap.initialize.dart Failed to load resource - where is it?
body: <p>I have a Dart (1_16_0_dev_2) Polymer web app. I see <a href="https://stackoverflow.com/questions/34954862/dart-app-cannot-find-index-bootstrap-initialize-dart">>the problem here&lt;</a> , but I still have it. My yaml is :</p>
  
  <pre><code>dependencies:
    browser: ^0.10.0
    polymer: ^1.0.0-rc.16
    polymer_elements: ^1.0.0-rc.8
  
  transformers:
  - polymer:
      entry_points:
        - web/index.html
  - $dart2js:
      $include: '**/*.bootstrap.initialize.dart' (I've tried with and without this line)
      minify: true
      commandLineOptions:
      - --trust-type-annotations
      - --trust-primitives
  </code></pre>
  
  <p>I've tried without the dart2js too. I can view my website in (some!?) Chromes on different devices, but Dartium gives this complaint </p>
  
  <pre><code>http://www.xxx/index.bootstrap.initialize.dart Failed to load resource: the server responded with a status of 404 (Not Found)
  </code></pre>
  
  <p>(and I assume it's why FireFox and Edge show a blank page).</p>
  
  <p>What am I doing wrong please?
  Thanks,
  cheers,
  s</p>
