如何在初始化ChangeNotifierProvider前加载数据库？

import 'package:flutter/material.dart';
import 'package:provider/provider.dart';
import 'package:mysql1/mysql1.dart';

// 创建数据库连接
final conn = await MySqlConnection.connect(ConnectionSettings(
  host: 'localhost',
  port: 3306,
  user: 'username',
  password: 'password',
  db: 'database',
));

// 初始化数据库
await conn.query('CREATE TABLE IF NOT EXISTS users (id INT, name VARCHAR(255))');

// 创建数据访问对象
class UserDao {
  Future<List<Map<String, dynamic>>> getUsers() async {
    final results = await conn.query('SELECT * FROM users');
    return results.toList();
  }
}

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ChangeNotifierProvider(
      create: (context) {
        // 加载数据库中的数据
        final userDao = UserDao();
        final users = userDao.getUsers();
        
        return MyChangeNotifier(users);
      },
      child: MaterialApp(
        title: 'My App',
        home: MyHomePage(),
      ),
    );
  }
}

class MyChangeNotifier with ChangeNotifier {
  final List<Map<String, dynamic>> users;
  
  MyChangeNotifier(this.users);
  
  // ...
}

class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final myChangeNotifier = Provider.of<MyChangeNotifier>(context);
    
    // 使用加载的数据
    final users = myChangeNotifier.users;
    
    // ...
  }
}
