title: Video inside Html content does not appear on flutter
body: <p>I have HTML content which includes texts, images, and videos. The text and images work fine without any problems, but the videos never show up. I have tried many plugins regarding HTML, for example: flutter_html and flutter_html_view, and they all do not show the video.</p>
  
  <p>Sample of the HTML content with video that I want to display:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;p&gt;Hello world 25-3-2019 :&lt;/p&gt;
  &lt;p&gt;&amp;nbsp;&lt;/p&gt;
  &lt;p&gt;
      &lt;iframe 
          src="https://www.youtube.com/embed/W8TrvLoPrfQ" 
          width="400" 
          height="300" 
          frameborder="0"&gt;&lt;/iframe&gt;
  &lt;/p&gt;
  </code></pre>
  
  <p>Does anyone have an idea about displaying this content inside a widget?</p>
