Flutter 如何使用可膨胀带颤振？

我想在我的应用程序中有一个扩展行为。但在扩展时，它会抛出一个renderroverflow错误

这是我的密码

ExpandableNotifier(
      child: Container(
        height: 400.0,
        width: double.infinity,
        alignment: Alignment.bottomCenter,

        margin: EdgeInsets.all(8.0),

                     //removed bracktes to make ques cleaner

我尝试在SingleChildScrollView中包装我的文本，但没有任何帮助

我什么都试过了，但都没用。我试过阅读文档，但没用。我找不到任何有用的东西

请帮帮我，我被困在这两天了
