颤振涡旋在滑块中不起作用

Question

我有一个按钮，当点击它退出显示对话框，其中有一个滑块(slider_pro -包)。我是通过json得到照片的。照片出来的很好，但水平滚动不起作用。如何将其放入显示对话框- slider_pro中，并将导航放在那里。提前谢谢你。您可以在我的代码中看到更多细节，请按照链接进行操作。https://github.com/akbarsulaymonov/Slider_ShowDialog/blob/master/1

您可以复制粘贴，运行下面的完整代码

您可以使用List<Widget>.generate和InkWell

代码段

images: List<Widget>.generate(
          data.length,
          (index) => InkWell(
            onTap: () {
              Navigator.push(
                context,
                MaterialPageRoute(
                    builder: (context) => SecondRoute(
                        url: data[index]["url"])),
              );
            },
            child: CachedNetworkImage(
                imageUrl: data[index]["url"],
