title: What is a Future and how do I use it?
body: <p>I get the following error:</p>
  <pre class="lang-none prettyprint-override"><code>A value of type 'Future&lt;int&gt;' can't be assigned to a variable of type 'int'
  </code></pre>
  <p>It might be another type instead of <code>int</code>, but basically the pattern is</p>
  <pre class="lang-none prettyprint-override"><code>A value of type 'Future&lt;T&gt;' can't be assigned to a variable of type 'T'
  </code></pre>
  <p>So...</p>
  <ul>
  <li>What exactly is a <code>Future</code>?</li>
  <li>How do I get the actual value I want to get?</li>
  <li>What widget do I use to display my value when all I have is a <code>Future&lt;T&gt;</code>?</li>
  </ul>
