title: Dart : How to get second to last item in a List
body: <p>I would like to get the second to last item in a <code>List</code>, similarly than with getter <code>last</code>.</p>
  <p>I tried the following :</p>
  <pre class="lang-dart prettyprint-override"><code>final list = [1, 2, 3, 4, 5];
  
  final secondToLast = (list..removeLast()).last; // Mutates the List
  </code></pre>
  <p>However it mutates the <code>List</code>.</p>
