title: ListView in an ExpansionPanel/ExpansionTile
body: <p>I have a few long lists and want to display everything on screen. Because it isn't organised I want to create an <code>ExpansionTile</code> so the user can open and close the desired list. I'm only not able to create this the way I want to. I can open my <code>ExpansionTile</code> but I can't scroll down to view the numbers on the bottom. Can I use <code>ExpansionTile</code> in this case or does an other Widget do the job better?</p>
  <p>Following is a simplified version of my code:</p>
  <pre><code>void main() async {
    runApp(ExpansionTileDemo());
  }
  
  
  class ExpansionTileDemo extends StatefulWidget {
    @override
    _ExpansionTileDemoState createState() =&gt; _ExpansionTileDemoState();
  }
  
  class _ExpansionTileDemoState extends State&lt;ExpansionTileDemo&gt; {
    List&lt;int&gt; numbers = [];
  
    @override
    void initState() {
      for (int i = 0; i &lt; 100; i++) {
        numbers.add(i);
      }
      super.initState();
    }
  
    @override
    Widget build(BuildContext context) {
      return MaterialApp(
        home: Scaffold(
          appBar: AppBar(
            title: Text(&quot;ExpansionTile demo&quot;),
          ),
          body: ListView(
            children: [
              ExpansionTile(
                title: Text('List 1'),
                children: [
                  ListView.builder(
                    shrinkWrap: true,
                    itemCount: numbers.length,
                    itemBuilder: (context, index) =&gt; ListTile(
                      title: Text(
                        &quot;${numbers[index]}&quot;,
                      ),
                    ),
                  )
                ],
              ),
              ExpansionTile(
                title: Text('List 2'),
                children: [
                  ListView.builder(
                      shrinkWrap: true,
                      itemCount: numbers.length,
                      itemBuilder: (context, index) {
                        print(numbers[index]);
                        return ListTile(
                          title: Text(
                            &quot;${numbers[index]}&quot;,
                          ),
                        );
                      })
                ],
              ),
            ],
          ),
        ),
      );
    }
  }
