title: Dart: mapping a list (list.map)
body: <p>I have a list of <code>String</code>s, e.g., </p>
  
  <pre><code>var moviesTitles = ['Inception', 'Heat', 'Spider Man'];
  </code></pre>
  
  <p>and wanted to use <code>moviesTitles.map</code> to convert them to a list of <code>Tab</code> <code>Widget</code>s in Flutter.</p>
