在flutter应用程序中有两个水平列表视图。当放置第二个列表视图时出现错误。 我使用nestedscrollview来滚动页面，但是这个问题没有解决。如何管理小部件的高度，以便不会发生此错误？我尝试为第二个listview设置高度，但仍然出错 看我的代码：

  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
        theme: ThemeData(
          fontFamily: "Vazir",primaryColor: Colors.red,accentColor: Colors.green,),debugShowCheckedmodeBanner: false,home: Directionality(
          textDirection: TextDirection.rtl,child: Scaffold(
              drawer: myDrawerLayout(context),body: nestedScrollView(
                headerSliverBuilder: (context,bool innerScroll) {
                  return <Widget>[
                    SliverAppBar(
                        title: Text(
                      "فروشگاه",style: TextStyle(fontFamily: "Vazir"),))
                  ];
                },body: Column(
                  children: <Widget>[
                    _imageSlider(),_explanationTextForAmazingProduct(),//text for listview explanation
                    _SizedBox(
                      height: 190,child: ListView.builder(
                          scrollDirection: Axis.horizontal,padding: EdgeInsets.all(8),shrinkWrap: true,itemCount: productList.length,itemBuilder: (BuildContext context,int index) {
                            return productList.isEmpty || productList == null
                                ? wiatingView()
                                : Card(
                                    child: Container(
                                      width: 200,height: 70,child: Column(
                                        children: <Widget>[
                                          Padding(
                                            padding:
                                                const EdgeInsets.only(top: 8),child: Container(
                                              width: 80,height: 80,decoration: BoxDecoration(
                                                  image: DecorationImage(
                                                      image: NetworkImage(
                                                          productList[index]
                                                              .getImage()))),Padding(
                                            padding: const EdgeInsets.only(
                                                right: 8,left: 8,top: 8),child: Center(
                                              child: Text(productList[index]
                                                  .getTitle()),Center(
                                            child: Text(
                                              productList[index].getPrice(),style: TextStyle(
                                                  color: Colors.green),],);
                          }),explanationTextForMostSellProduct(),//text for second listview explanation
                    Expanded(
                      child: ListView.builder(
                          scrollDirection: Axis.horizontal,height: 150,)
                  ],)),));
  }
