Flutter:如何弹出多个参数

class MyDialog extends StatelessWidget {
  final String param1;
  final String param2;

  MyDialog({this.param1, this.param2});

  @override
  Widget build(BuildContext context) {
    return AlertDialog(
      title: Text('多个参数弹窗'),
      content: Column(
        children: [
          Text('参数1: $param1'),
          Text('参数2: $param2'),
        ],
      ),
      actions: [
        FlatButton(
          child: Text('关闭'),
          onPressed: () {
            Navigator.of(context).pop();
          },
        ),
      ],
    );
  }
}

void showMyDialog(BuildContext context) {
  showDialog(
    context: context,
    builder: (BuildContext context) {
      return MyDialog(param1: '参数1值', param2: '参数2值');
    },
  );
}
