body: <p>I am using  <code>photo_manager</code> plugin, but I am stuck on how to filter only the following files</p>
  <p>images png , jpg</p>
  <p>videos mp4</p>
  <p>they don't mention on their docs of how to implement it</p>
  <p>I have the following code but I can't find the method for my need</p>
  <pre><code>List&lt;AssetPathEntity&gt; albums = await 
  
  PhotoManager.getAssetPathList(onlyAll: true,filterOption: FilterOptionGroup(???? );    
  
  List&lt;AssetEntity&gt; photos = await albums[0].getAssetListPaged(  page: 0, size: 50, );
  </code></pre>
