Flutter:如何将AlertDialog的操作放在其主体的顶部？

AlertDialog(
  title: Text('提示'),
  content: Column(
    crossAxisAlignment: CrossAxisAlignment.start,
    mainAxisSize: MainAxisSize.min,
    children: [
      Text('这是一个AlertDialog的主体内容'),
      SizedBox(height: 10),
      Text('其他内容...'),
    ],
  ),
  actions: [
    FlatButton(
      onPressed: () {
        // 点击操作按钮的回调函数
      },
      child: Text('操作按钮'),
    ),
  ],
)
