如何用sliver实现横向网格滚动

Question

如何使用sliver:[]获得类似于此示例的水平网格视图。 我尝试使用此处给出的示例，但它在子项中使用多个容器来获得所需的结果。 还尝试将其提供给 list.generate，但这似乎不起作用，或者我真的不知道如何使用它。

注意：我在 [ ] 里面还有其他多个滚动列表

这是我正在做的工作，但它以列表形式出现：

  body: CustomScrollView(
    slivers: [
      SliverPadding(
        padding: EdgeInsets.symmetric(horizontal: 16.0),
        sliver: SliverGrid(
          gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
            childAspectRatio: 2,
            crossAxisSpacing: 16,
            mainAxisSpacing: 16,
            crossAxisCount: 2,
          ),
          delegate: SliverChildBuilderDelegate(
            (BuildContext context, int i) {
              return InkWell(
                onTap: () {},
                child: ClipRRect(
                  clipBehavior: Clip.antiAlias,
                  borderRadius: BorderRadius.circular(8),
                  child: Container(
                    height: 200,
                    width: double.infinity,
                    decoration: BoxDecoration(
                        image: DecorationImage(
                          image:
                              CachedNetworkImageProvider('categoryImage'),
                          fit: BoxFit.cover,
                          onError: (exception, stackTrace) =>
                              LoadingImage(),
                        ),
                        gradient: const LinearGradient(
                          begin: Alignment.topLeft,
                          end: Alignment.bottomRight,
                          colors: [
                            Color(0x1FFFFFFF),
                            Color(0x463B3B3B),
                          ],
                        ),
                        borderRadius: BorderRadius.circular(8),
                        boxShadow: [
                          BoxShadow(
                              color: Colors.grey.shade900,
                              offset: const Offset(1, 1),
                              spreadRadius: 1,
                              blurRadius: 50,
                              blurStyle: BlurStyle.outer),
                        ]),
                    child: Container(
                      padding: const EdgeInsets.all(10),
                      height: 100,
                      color: Colors.transparent,
                      alignment: Alignment.bottomLeft,
                      width: double.infinity,
                      child: Text(
                        "title",
                        overflow: TextOverflow.ellipsis,
                        style: Theme.of(context).textTheme.bodyText1!,
                      ),
                    ),
                  ),
                ),
              );
            },
            childCount: count.length,
          ),
        ),
      ),
    ],

只需在CustomScrollView中添加scrollDirection: Axis.horizontal, ，只需更改我的图像，希望对您有所帮助

完整的小部件：

CustomScrollView(
    scrollDirection: Axis.horizontal,
    slivers: [
      SliverPadding(
        padding: EdgeInsets.symmetric(horizontal: 16.0),
        sliver: SliverGrid(
          gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
            childAspectRatio: 2,
            crossAxisSpacing: 16,
            mainAxisSpacing: 16,
            crossAxisCount: 2,
          ),
          delegate: SliverChildBuilderDelegate(
            (BuildContext context, int i) {
              return InkWell(
                onTap: () {},
                child: ClipRRect(
                  clipBehavior: Clip.antiAlias,
                  borderRadius: BorderRadius.circular(8),
                  child: Container(
                    height: 200,
                    width: double.infinity,
                    decoration: BoxDecoration(

                        gradient: const LinearGradient(

                          end: Alignment.bottomRight,

                              offset: const Offset(1, 1),
                              spreadRadius: 1,
