我得到了那个臭名昭著的错误，我无法解决。

RenderBox was not laid out: RenderRepaintBoundary#03a24 relayoutBoundary=up14 NEEDS-PAINT
'package:flutter/src/rendering/box.dart':
Failed assertion: line 2001 pos 12: 'hasSize

我尝试了各种各样的小部件 Package 。错误在Container（）上。在那个容器中，我试图显示10个最新的产品，水平滚动，并从firestore数据库中获取。下面，我显示了商店列表，垂直滚动，他们没有引起任何问题，也没有水平滚动小部件，显示类别。
我有一个选项卡屏幕，在TabView中我有这个类：

UserHomeMerch({Key? key}) : super(key: key);

UserHomeMerchState createState() => UserHomeMerchState();

我的productItem小部件是一张卡片，点击显示bottomModal，如下所示：

class ProductItem extends StatelessWidget {
final String productId;
final String productName;
final String productDescription;
final num productPrice;
final num count;
final List<dynamic> images;
final String outletID, merchId;

ProductItem(
  {required this.productId,
  required this.productName,
  required this.productDescription,
  required this.productPrice,
  required this.count,
  required this.images,
  required this.outletID,
  required this.merchId});

@override

          height: 250,
          //width: 100,
        ),
        ListTile(

          ),
          subtitle: Text(

          ),

            ),
            label: Text(
              Languages.of(context)!.seeProf,
            ),
            style: ButtonStyle(
              shape: MaterialStateProperty.all<RoundedRectangleBorder>(
                RoundedRectangleBorder(
                  borderRadius: BorderRadius.circular(10),
                  side: BorderSide(

              ),
            ),
          ),
        ),
        Divider(thickness: 2),
      ],
    ),
  ),
);
}
}

请，帮我解决这个问题。非常感谢你提前！
