title: How to extract Dart/Flutter video metadata
body: <p>I am developing a flutter demo app. I want to use metadata about a video in my phone storage. I am able to extract the path of that video, but don't know how to extract its metadata in dart/flutter.</p>
  
  <p>I need the following metadata:</p>
  
  <ol>
  <li>Duration of video</li>
  <li>Name of video</li>
  <li>Size of video</li>
  <li>When video was taken</li>
  </ol>
