title: What does "< >" mean in Dart?
body: <p>Through an online Dart course, I've found some values bracketed with "less than" and "greater than" marks such as <a href="https://api.dartlang.org/stable/2.1.0/dart-core/List-class.html" rel="noreferrer">"List&lt; E >"</a>.</p>
  
  <p>e.g.</p>
  
  <pre><code>List&lt;int&gt; fixedLengthList = new List(5);
  </code></pre>
  
  <p>I couldn't find a direct answer online, probably because that question was too basic. Could someone explain what those marks exactly indicate? Or any links if possible.</p>
