body: <p>I am just doing some practice in flutter and don't know how to get URI of all the images and videos present in my storage in flutter.</p>
  
  <p>Here is my code,</p>
  
  <pre><code>class Gallery extends StatefulWidget {
  @override
  _GalleryState createState() =&gt; new _GalleryState();
  }
  
  class _GalleryState extends State&lt;Gallery&gt; {
  List&lt;String&gt; _uriList = new List&lt;String&gt;();
  
  
  @override
  void initState() {
  super.initState();
  setState((){
    _uriList.add("WHat to enter here??");
  });
  }
  
  @override
  Widget build(BuildContext context) {
  return new MaterialApp(
    title: "Gallery",
    home: new Scaffold(
      appBar: new AppBar(
        title: new Text("Gallery"),
      ),
      body: new ListView.builder(
        itemCount: _uriList.length,
        itemBuilder: (BuildContext context, int index){
  
        },
      ),
    ),
  );
  }
  }
  </code></pre>
