title: Transform data when parsing a JSON string using Dart
body: <p>I'm using the <code>parse()</code> function provided in <code>dart:json</code>. Is there a way to transform the parsed data using <code>parse()</code>? I'm thinking of something similar to the <code>reviver</code> argument when parsing JSON using JavaScript:</p>
  
  <pre class="lang-dart prettyprint-override"><code>JSON.parse(text[, reviver])
  </code></pre>
