title: How to use RadioListTile inside of a ListView.builder?
body: <p>I'm trying to make a selectable listview.</p>
  
  <p>I chose <code>RadioListTile</code> ,but it doesn't need to be with <code>Radios</code>,I would be happy with the background color changing of a <code>ListTile</code> on tapping the item.
  So in my current code I have <code>RadioListTiles</code>,but it doesn't checks on tap,and I think it would let to check more than one,because its in a <code>ListView.builder</code>,but I don't know since I'm new to flutter,and it's not working.</p>
  
  <p>Here is the code:</p>
  
  <pre><code>ListView.builder(
    scrollDirection: Axis.vertical,
    itemCount: items.length,
    itemBuilder: (context, index) {
      return RadioListTile&lt;LoadList&gt;(
        selected: isSelected,
        groupValue: radiolist,
        value: items[index],
        onChanged: (LoadList value) {
          radiolist.GetHours(value.hours);
          print("CurrentSelected $index");
          setState(() {
            isSelected = true;
          });
        },
        title: new Text(index),
      );
    },
  ),
  </code></pre>
