当我尝试使用GridView.count()“技能”下构建身体时，如设计所示，它不起作用，即网格视图根本不可见。我知道这可能是因为我在 Column 中使用它，并且建议的解决方案是用Expanded小部件包装它，但它也不起作用。然后它给出了“不正确使用 ParentDataWidget”错误。那么任何人都可以帮我解决这个问题吗？
代码的相关部分：
Widget _buildAboutView() {
return SingleChildScrollView(
child: Column(
children: [
AboutTile(
title: 'Bio',
child: Text(
'I’ve always had a natural curiosity for machinery. As a child, I loved taking things apart and putting them back together. By the age of 12, I was building components for use in construction and even making a bit of pocket money for my troubles.',
softWrap: true,
),
),
AboutTile(
title: 'Skills',
child: Container(
height: 100,
child: Expanded(
child: GridView.count(
crossAxisCount: 4,
