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
-
添加依赖
在
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。 -
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(); });
-
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; } }
-
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 onLaunch
、onResume
和 onMessage
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"
}
}
