列表视图在 ExpansionTile 中不起作用

我试图在 ExpansionTile 中显示一个 listview.builder 但它抛出了一些异常

Card(
       child: ExpansionTile(
           leading: Icon(
              Icons.stars,
              color: Colors.pinkAccent,
           ),
           title: Text('Reviews',
                  style: Theme.of(context).textTheme.title,
                          ),
                children: [
                    ListView.builder(
                        itemCount: 5,
                        itemBuilder: (_, i) {
                          return (Text('item $i'));
                     })
                   ],
             ),
     ),
