有没有办法为flutter中的警示对话创建一个通用的类？

import 'package:flutter/material.dart';

class AlertDialogUtils {
  static void showAlertDialog(BuildContext context, String title, String message) {
    showDialog(
      context: context,
      builder: (BuildContext context) {
        return AlertDialog(
          title: Text(title),
          content: Text(message),
          actions: <Widget>[
            FlatButton(
              child: Text('确定'),
              onPressed: () {
                Navigator.of(context).pop();
              },
            ),
          ],
        );
      },
    );
  }
}

import 'package:flutter/material.dart';
import 'alert_dialog_utils.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('警示对话框示例'),
        ),
        body: Center(
          child: RaisedButton(
            child: Text('显示警示对话框'),
            onPressed: () {
              AlertDialogUtils.showAlertDialog(
                context,
                '警示',
                '这是一个警示对话框示例。',
              );
            },
          ),
        ),
      ),
    );
  }
}
