ListView внутри ExpansionTile не работает

Question

просмотр списка не работает внутри ExpansionTile

Я пытался показать listview.builder внутри ExpansionTile, но он выдает некоторые исключения

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'));
                     })
                   ],
             ),
     ),

Answer 1

Добавить как термоусадочную пленку, так и контроллер в ListView.builder

final ScrollController _scrollController = ScrollController();


    ListView.builder(
          controller: _scrollController,
           shrinkWrap: true,
    ...

Answer 2

Размер вашего ListView по вертикали неограничен, что делает невозможным его рендеринг. Установите shrinkWrap свойство ListView на true, чтобы обойти это.
