我已经完成了this发布
对于嵌套滚动，但它不是正确的方式，根据我的解释，在this视频从官方flutter频道
我想实现下面的布局

列表标题，如索赔要求的凭据，索赔收到的凭据，待定的请求等是动态的，将来自后端。此外，这些列表标题中的每一项，如模块1：设计金融服务也是动态的
所以我需要列表中的列表
我正在使用CustomScroll，但无法实现内部列表视图
我正在寻找一个惰性列表选项，而不仅仅是将内部列表Map到列或列表上，因为内部列表可能包含100个项目
以下是我取得的成果

下面是示例代码

class MyHomePage extends StatelessWidget {
  const MyHomePage({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Stack(
        children: [
          HeaderGradient(),
          Positioned(
            top: 110,
            left: 0,
            right: 0,
            bottom: 0,
            child: Container(
              padding: const EdgeInsets.all(8.0),
              decoration: const BoxDecoration(
                color: grayColor,
                borderRadius: BorderRadius.only(
                  topLeft: Radius.circular(20),
                  topRight: Radius.circular(20),
                ),
              ),
              child: CustomScrollView(
                slivers: [
                  const SliverToBoxAdapter(
                    child: ManageCredentialHeader(),
                  ),
                  SliverList(
                      delegate: SliverChildBuilderDelegate((context, index) {
                    return ManageCredentialCard();
                  }, childCount: 10))
                ],
              ),
            ),
          )
        ],
      ),
    );
  }
}

以及

class ManageCredentialCard extends StatelessWidget {
  const ManageCredentialCard({super.key});

  @override
  Widget build(BuildContext context) {
    return Card(
      color: Theme.of(context).colorScheme.background,
      child: Padding(
        padding: const EdgeInsets.symmetric(horizontal: 8, vertical: 4),
        child: Column(
          children: [
            const ManageCredentialCardHeader(),

            const ManageCredentialCardItem()
          ],
        ),
      ),
    );
  }
}

ManageCredentialCardItem是内部列表
当我将ManageCredentialCardItem Package 到ListView.builder中时，我收到错误消息

RenderFlex children have non-zero flex but incoming height constraints are
unbounded.
When a column is in a parent that does not provide a finite height constraint,
for example if it is
in a vertical scrollable, it will try to shrink-wrap its children along the
vertical axis. Setting a
flex on a child (e.g. using Expanded) indicates that the child is to expand to
fill the remaining
space in the vertical direction.
