如何在单击推送通知时在flutter应用程序中打开特定页面

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

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

class MyApp extends StatelessWidget {
  final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
      FlutterLocalNotificationsPlugin();

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Push Notification Demo',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter Push Notification Demo'),
        ),
        body: Center(
          child: Text('Welcome to the app!'),
        ),
      ),
    );
  }

  // 初始化推送通知插件
  Future<void> initializeNotifications() async {
    const AndroidInitializationSettings initializationSettingsAndroid =
        AndroidInitializationSettings('app_icon');
    final InitializationSettings initializationSettings =
        InitializationSettings(android: initializationSettingsAndroid);
    await flutterLocalNotificationsPlugin.initialize(initializationSettings);
  }

  // 处理推送通知回调
  Future<void> handleNotificationClick(Map<String, dynamic> message) async {
    // 解析推送通知中的数据
    final String pageId = message['data']['page_id'];

    // 根据页面标识符导航到相应页面
    if (pageId == 'home') {
      Navigator.push(
        context,
        MaterialPageRoute(builder: (context) => HomePage()),
      );
    } else if (pageId == 'profile') {
      Navigator.push(
        context,
        MaterialPageRoute(builder: (context) => ProfilePage()),
      );
    }
  }
}

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Home Page'),
      ),
      body: Center(
        child: Text('Welcome to the home page!'),
      ),
    );
  }
}

class ProfilePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Profile Page'),
      ),
      body: Center(
        child: Text('Welcome to the profile page!'),
      ),
    );
  }
}
