如何在Flutter中创建这种类型的对话框？

AlertDialog(
  title: Text('Dialog Title'),
  content: Text('Dialog Content'),
  actions: [
    FlatButton(
      child: Text('Cancel'),
      onPressed: () {
        // 取消按钮的回调函数
      },
    ),
    FlatButton(
      child: Text('OK'),
      onPressed: () {
        // 确定按钮的回调函数
      },
    ),
  ],
)

SimpleDialog(
  title: Text('Dialog Title'),
  children: [
    SimpleDialogOption(
      child: Text('Option 1'),
      onPressed: () {
        // 选项1的回调函数
      },
    ),
    SimpleDialogOption(
      child: Text('Option 2'),
      onPressed: () {
        // 选项2的回调函数
      },
    ),
  ],
)

showModalBottomSheet(
  context: context,
  builder: (BuildContext context) {
    return Container(
      child: Column(
        children: [
          ListTile(
            title: Text('Option 1'),
            onTap: () {
              // 选项1的回调函数
            },
          ),
          ListTile(
            title: Text('Option 2'),
            onTap: () {
              // 选项2的回调函数
            },
          ),
        ],
      ),
    );
  },
)

class CustomDialog extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Dialog(
      child: Container(
        padding: EdgeInsets.all(16.0),
        child: Column(
          mainAxisSize: MainAxisSize.min,
          children: [
            Text('Dialog Title'),
            SizedBox(height: 16.0),
            Text('Dialog Content'),
            SizedBox(height: 16.0),
            Row(
              mainAxisAlignment: MainAxisAlignment.end,
              children: [
                FlatButton(
                  child: Text('Cancel'),
                  onPressed: () {
                    // 取消按钮的回调函数
                  },
                ),
                FlatButton(
                  child: Text('OK'),
                  onPressed: () {
                    // 确定按钮的回调函数
                  },
                ),
              ],
            ),
          ],
        ),
      ),
    );
  }
}

showDialog(
  context: context,
  builder: (BuildContext context) {
    return CustomDialog();
  },
);
