在paint期间抛出：'package:flutter/src/rendering/sliver_multi_box_adaptor.dart'：失败的断言：第544行位置12：'child.hasSize'：不是真的

如何解决在paint期间抛出：'package:flutter/src/rendering/sliver_multi_box_adaptor.dart'：失败的断言：第544行位置12：'child.hasSize'：不是真的

我想构建一个旋转木马滑块，显示我之前制作的列表的产品图像，带有一个 onpressed 功能，可以导航到另一个显示点击产品详细信息的路线，我的产品列表名称为 List.

当我在 Home_Page Route 中调用 Carousel Slider 方法时，我需要“itemBuilder: (context,index)”，所以我将它包装在 ListView.builder 中并将其包装到一个具有定义高度和宽度的容器中以避免错误上面，但在运行应用程序时，在 Carousel Slider 应该在的地方没有任何显示......我这样做对吗？

我的轮播滑块代码：

    class CustomCarouselHomePage extends StatefulWidget {
  final List<String> Productzz;
  final Function press;
  final Productz productz;

  CustomCarouselHomePage(
      {required this.Productzz,required this.press,required this.productz});

  @override
  _CustomCarouselHomePageState createState() => _CustomCarouselHomePageState();
}

class _CustomCarouselHomePageState extends State<CustomCarouselHomePage> {
  int activeIndex = 0;
   late final Function press;
   late final Productz productz;

  setActiveDot(index) {
    setState(() {
      activeIndex = index;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Stack(
      clipBehavior: Clip.none,children: <Widget>[
        Container(
          width: MediaQuery.of(context).size.width,child: CarouselSlider(
            options: CarouselOptions(
              autoplayInterval: Duration(seconds: 4),autoplayCurve: Curves.fastLinearToslowEaseIn,autoplayAnimationDuration: Duration(seconds: 2),viewportFraction: 1.0,onPageChanged: (index,reason) {
                setActiveDot(index);
              },),items: widget.Productzz.map((productzz) {
              return Builder(
                builder: (BuildContext context) {
                  return GestureDetector(
                    onTap: () => press (),child: Stack(
                     // crossAxisAlignment: CrossAxisAlignment.start,children: <Widget>[
                      Container(
                        width: MediaQuery.of(context).size.width,child: Hero(
                          tag: "${productz.id}",child: Image.asset(productz.item_image),Container(
                        width: MediaQuery.of(context).size.width,color: Colors.black.withOpacity(0.2),],);
                },);
            }).toList(),Positioned(
          left: 0,right: 0,bottom: 10,child: Row(
              mainAxisAlignment: MainAxisAlignment.end,children: List.generate(widget.Productzz.length,(idx) {
                return activeIndex == idx ? ActiveDot() : InactiveDot();
              })),)
      ],);
  }
}

class ActiveDot extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.only(right: 8.0),child: Container(
        width: 25,height: 8,decoration: Boxdecoration(
          color: white,borderRadius: BorderRadius.circular(5),);
  }
}

class InactiveDot extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.only(right: 8.0),child: Container(
        width: 8,decoration: Boxdecoration(
          color: grey,);
  }
}

当我在 Home_Page Route 中调用 Carousel Slider 方法时的代码：

Container(
  height:MediaQuery.of(context).size.height,child: ListView.builder(
  itemBuilder: (context,index) => CustomCarouselHomePage(
    Productzz: [],productz: productz[index],press: () => Navigator.push(
        context,MaterialPageRoute(
          builder: (context) => DetailsScreen(
            productz: productz[index],)),
