title: The best way to parse a JSON in Dart
body: <p>I'm trying to load a json file from a URL and parse it within Dart. So I had tried the following code as suggested from some links when I google for it:</p>
  
  <pre><code>   HttpRequest.getString("hellknight2.js").then((response)
     {
       var model = new JSON.parse(response);
     });
  </code></pre>
  
  <p>However, it seems to not work anymore on Dart SDK version 0.4.3.5_r20602. What is the current best way to get a Json file mapped to an object in Dart?</p>
