Flutter推送通知操作插件apn_actions的使用

Flutter推送通知操作插件apn_actions的使用

apn_actions 是一个用于管理 Riverpod 状态的工具库。它可以帮助开发者更方便地处理推送通知相关的逻辑。

使用步骤

  1. 添加依赖

    pubspec.yaml 文件中添加 apn_actions 依赖:

    dependencies:
      apn_actions: ^1.0.0
    

    然后运行 flutter pub get 来安装依赖。

  2. 初始化 Riverpod Provider

    创建一个 Riverpod provider 来管理推送通知的状态:

    import 'package:flutter_riverpod/flutter_riverpod.dart';
    import 'package:apn_actions/apn_actions.dart';
    
    final notificationProvider = StateNotifierProvider<NotificationController, String>((ref) {
      return NotificationController();
    });
    
  3. 创建 NotificationController

    创建一个 NotificationController 来处理推送通知的逻辑:

    class NotificationController extends StateNotifier<String> {
      NotificationController() : super('');
    
      void handleNotification(String message) {
        state = message;
      }
    }
    
  4. 监听推送通知

    使用 ApnActionHandler 来监听推送通知,并将消息传递给 Riverpod provider:

    import 'package:flutter/material.dart';
    import 'package:flutter_riverpod/flutter_riverpod.dart';
    import 'package:apn_actions/apn_actions.dart';
    
    void main() {
      runApp(ProviderScope(child: MyApp()));
    }
    
    class MyApp extends StatelessWidget {
      @override
      Widget build(BuildContext context) {
        return MaterialApp(
          home: HomeScreen(),
        );
      }
    }
    
    class HomeScreen extends ConsumerWidget {
      @override
      Widget build(BuildContext context, ScopedReader watch) {
        final notificationState = watch(notificationProvider);
    
        return Scaffold(
          appBar: AppBar(title: Text('Push Notification Example')),
          body: Center(
            child: Column(
              mainAxisAlignment: MainAxisAlignment.center,
              children: [
                Text('Notification Message:'),
                Text(notificationState),
              ],
            ),
          ),
        );
      }
    }
    
    // 初始化 ApnActionHandler
    void initializeApnActions() {
      ApnActionHandler().initialize((message) {
        context.read(notificationProvider.notifier).handleNotification(message);
      });
    }

apn_actions 是一个 Flutter 插件,用于处理 Apple 推送通知 (APNs) 中的自定义操作。它允许你在接收到推送通知时执行特定的操作,例如打开一个特定的页面、执行某个函数等。

以下是如何使用 apn_actions 插件的基本步骤:

1. 添加依赖

首先,在你的 pubspec.yaml 文件中添加 apn_actions 插件的依赖:

dependencies:
  flutter:
    sdk: flutter
  apn_actions: ^1.0.0  # 请使用最新版本

然后运行 flutter pub get 以安装依赖。

2. 配置 iOS 项目

确保你的 iOS 项目已经正确配置了推送通知功能。你需要在 AppDelegate.swift 文件中添加以下代码来注册推送通知:

import UIKit
import Flutter

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate, UNUserNotificationCenterDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    UNUserNotificationCenter.current().delegate = self
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }

  override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let token = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
    print("APNs token: \(token)")
  }

  override func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
    print("Failed to register for remote notifications: \(error.localizedDescription)")
  }

  func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    let userInfo = response.notification.request.content.userInfo
    // Handle the notification action here
    completionHandler()
  }
}

3. 在 Flutter 中使用 apn_actions

在你的 Flutter 代码中,你可以使用 apn_actions 插件来处理推送通知中的自定义操作。

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

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

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  late ApnActions _apnActions;

  @override
  void initState() {
    super.initState();
    _apnActions = ApnActions();

    // 监听推送通知的操作
    _apnActions.configure(
      onLaunch: (Map<String, dynamic> message) async {
        print("App launched from notification: $message");
        // 处理从通知启动应用时的操作
      },
      onResume: (Map<String, dynamic> message) async {
        print("App resumed from notification: $message");
        // 处理应用从后台恢复到前台时的操作
      },
      onMessage: (Map<String, dynamic> message) async {
        print("Message received: $message");
        // 处理在前台接收到的通知
      },
    );
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('APN Actions Example'),
        ),
        body: Center(
          child: Text('APN Actions Example'),
        ),
      ),
    );
  }
}

4. 处理自定义操作

你可以在 onLaunchonResumeonMessage 回调中处理推送通知中的自定义操作。例如,如果你希望在用户点击通知时打开一个特定的页面,可以在 onResume 回调中实现:

onResume: (Map<String, dynamic> message) async {
  print("App resumed from notification: $message");
  if (message['action'] == 'open_page') {
    Navigator.push(
      context,
      MaterialPageRoute(builder: (context) => MyCustomPage()),
    );
  }
},

5. 发送带有自定义操作的推送通知

在服务器端发送推送通知时,你可以在通知的 payload 中添加自定义操作。例如:

{
  "aps": {
    "alert": {
      "title": "New Message",
      "body": "You have a new message"
    },
    "action": "open_page"
  }
}
