title: Stop showing error from HTTP or DIO request
body: <p>I have a problem when I get an error request from API (when server response 500).
  I am using <strong>dio</strong> or <strong>http</strong> plugin for <strong>flutter</strong> plug in. </p>
  
  <p>The problem is that flutter does not show any error. </p>

  </code></pre>
