尝试在颤振中创建嵌套列表视图

Question

我尝试制作嵌套 ListView ，父列表视图垂直滚动，子列表水平滚动但抛出此错误：

[错误：flutter/lib/ui/ui_dart_state.cc(177)] 未处理的异常： 'package:flutter/src/rendering/mouse_tracking.dart'：断言失败： 第 301 行 pos 12: '!_debugDuringDeviceUpdate': 不正确。

我还尝试将 column 与一个 ListView 和其他小部件垂直使用，并引发相同的错误

我可以通过使用 CustomScrollView Widget 及其委托 SliverChildListDelegate() 来解决这个问题，这是我的代码解决方案的这一部分

CustomScrollView(
      slivers: [
        SliverList(
          delegate: SliverChildListDelegate([
            Center(
              child: Column(
                children: [
                  Stack(
                    children: [
                      SingleChildScrollView(
                        scrollDirection: Axis.horizontal,
                        child: Row(
                          children: [
                            // height: MediaQuery.of(context).size.width,
                            Column(
                              children: [
                                InkWell(
                                  onTap: () {},
                                  onHover: (value) {
                                    if (value) {
                                      setState(() {
                                        assetImage =
                                            "assets/DentalChart/1.png";
                                        showHoverImage = true;
                                        hoverText = "Frontal Tooth";
                                        hoverWidth = 100;
                                        hoverHeight = 130;
                                        hoverOffset = Offset(100, 50);
                                      });
                                    } else {
