使用 CustomScrollView 时出现 Flutter RenderFlex 溢出错误

Question

即使我的所有小部件都在自定义滚动视图小部件中，我也会收到 renderfexlx 溢出错误。 我的脚手架主体有一列，该列有两个扩展小部件，我使用的所有其他小部件都在这些扩展小部件内。

我将第一列小部件包裹在 SliverFillRemaining 和 CustomScrollView 中，但仍然出现 renderflex 溢出错误

我尝试将 Column MainAxisSize 设置为 min 它不起作用。

我的代码

Scaffold(
          backgroundColor: Colors.transparent,
          body: CustomScrollView(
            reverse: true,
            slivers: [
              SliverFillRemaining(
                hasScrollBody: false,
                child: Column(
                  mainAxisSize: MainAxisSize.min,
                  children: [
                    Expanded(

                      child: Column(

将 customScrollView 包装在设备大小的容器中，或者可以是一个 safeArea 小部件
