title: flutter force set a property value to all objects from a list
body: <p>I have a list with custom objects and would like to iterate it and set the value to true/false. </p>
  
  <p>Seen the <code>setAll</code> method but would be something like I don't change only a property of each object in the list.</p>
  
  <p>My object looks something like:</p>
  
  <pre class="lang-dart prettyprint-override"><code>class Feature {
    String id;
    String title;
    String subtitle;
    IconData leftIcon;
    IconData topRightIcon;
    IconData bottomRightIcon;
    bool isEnable;
    Feature({this.title, this.subtitle, this.leftIcon, this.topRightIcon, this.bottomRightIcon, this.isEnable,this.id});
  }
  </code></pre>
  
  <p>So the object that would like to iterate would be: <code>List&lt;Feature&gt; features;</code></p>
  
  <p>How that's possible in flutter?</p>
