title: Why my flutter app's listview scroll not as smooth as the flutter gallery app?
body: <p>I created a release build of my scroll demo app using Flutter. I wonder why the listview scrolling of my app is NOT as smooth as the flutter gallery app. I used LG G5 for this test. </p>
  
  <p>Here's <a href="https://drive.google.com/open?id=0Bzt71EiA6gYLNG9DNFV1OVJJMDA" rel="noreferrer">a link to my app's demo</a></p>
  
  <p><strong>Edit:</strong>
  here is the code.</p>
  
  <pre><code>class ListViewSample extends StatelessWidget {
  @override
  Widget build(BuildContext buidContext) {
   return new Container(
    child: new Center(
      child: new ListView(
        children: createListTiles(),
      ),
     )
   );
  }
  
  List&lt;Widget&gt; createListTiles() {
   List&lt;Widget&gt; tiles = &lt;Widget&gt;[];
    for(int i = 0; i &lt; 40; i++) {
     int count = i + 1;
     tiles.add(
      new ListTile(
        leading: new CircleAvatar(
          child: new Text("$count"),
          backgroundColor: Colors.lightGreen[700],
        ),
        title: new Text("Title number $count"),
        subtitle: new Text("This is the subtitle number $count"),
      )
    );
   }
   return tiles;
  }
  </code></pre>
  
  <p>Do someone experience the same too?</p>
  
  <p>Thanks!</p>
