嗨，我正在尝试在前台收到通知时实现自定义铃声，铃声播放正常，停止正常，但是当应用程序在后台时，铃声正在响起，但无法停止，我发现handleBackgroundMessage正在创建新实例，并且在MyApp中具有对象的不同实例和
FirebaseMessaging.onMessageOpenedApp.listen((RemoteMessage message) {
NotificationHandler().onSelectNotification(json.encode(message.data));
});
这个方法是从 Myapp 调用的，所以它有不同的实例，任何人都可以建议我在这里做错了什么，我的代码如下
Future<void> handleBackgroundMessage(RemoteMessage message) async {
if (Platform.isAndroid) {
await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform);
} else if (Platform.isIOS) {
await Firebase.initializeApp();
}
final liveAstrologerController = Get.put(LiveAstrologerController());
final walletController = Get.put(WalletController());
final chatController = Get.put(ChatController);
final callController = Get.put(CallController());
final reportController = Get.put(ReportController());
if (message.notification!.title == "For Live Streaming Chat") {
Future.delayed(const Duration(milliseconds: 500)).then((value) async {
await localNotifications.cancelAll();
});
String sessionType = message.data["sessionType"];
if (sessionType == "start") {
String? liveChatUserName2 = message.data['liveChatSUserName'];
if (liveChatUserName2 != null) {
liveAstrologerController.liveChatUserName = liveChatUserName2;
liveAstrologerController.update();
}
String chatId = message.data["chatId"];
liveAstrologerController.isUserJoinAsChat = true;
liveAstrologerController.update();
liveAstrologerController.chatId = chatId;
int waitListId = int.parse(message.data["waitListId"].toString());
String time = liveAstrologerController.waitList
.where((element) => element.id == waitListId)
.first
.time;
liveAstrologerController.endTime = DateTime.now().millisecondsSinceEpoch +
1000 * int.parse(time.toString());
liveAstrologerController.update();
} else {}
} else if (message.notification!.title ==
"For timer and session start for live") {
liveAstrologerController.update();
} else if (message.notification!.title == "Start simple chat timer") {
} else {
try {
if (message.data.isNotEmpty) {
var messageData = json.decode((message.data['body']));
if (messageData['notificationType'] != null) {
if (messageData['notificationType'] == 7) {
// get wallet api call
await walletController.getAmountList();
} else if (messageData['notificationType'] == 8) {
chatController.startRingTone();
//AlarmHandler.scheduleAlarm();
chatController.chatList.clear();
chatController.update();
await chatController.getChatList(false);
debugPrint('chat resp-> $messageData');
} else if (messageData['notificationType'] == 2) {
//in background
callController.startRingTone();
await callController.getCallList(false);
} else if (messageData['notificationType'] == 9) {
reportController.reportList.clear();
reportController.update();
await reportController.getReportList(false);
} else if (messageData['notificationType'] == 12 ||
messageData['notificationType'] == 11 ||
messageData['notificationType'] == 10) {
liveAstrologerController.isUserJoinWaitList = true;
liveAstrologerController.update();

} } 我在我的应用程序中收到两个不同的聊天控制器实例的 hascode，并且 onselected 通知有
[log] chat hascode MyApp 445182886
[log] chat hascode bghandler 668612596
[log] chat hascode NotificationHandler 445182886
好吧，第一件事是我的方法是完全错误的，我正在使用自己的音频播放器来响铃并停止，这不是个好主意，因为 firebase 消息处理程序已经是一个单独运行的隔离，因此在其中创建的实例具有与 myapp 中创建的不同的引用，因此我发现的解决方案是直接使用 firebase 消息传递和 flutter_notification 的内置功能，我在这里做了什么 第一个 api 端你必须通过
[
'title' => 'Hey User you received a chat request from John Doe',
'body' => [
'description' => 'Hey you received a chat request from User' . $user[0]->name,
'notificationType' => 8,
'icon' => 'public/notification-icon/chat.png',
],
'android' => [
'notification' => [
'channel_id' => 'channel_id_13',
'sound' =>'app_sound' // don't use app_sound.mp3 or .wav only name
]
],
'apns' =>[
'payload' => [
'aps' => [
'sound' => 'app_sound.wav'
]
]
]
];
请记下您必须设置声音和channel_id
'android' => [
'notification' => [
'channel_id' => 'channel_id_13',
'sound' =>'app_sound'
]
],
并在 Android 清单和代码中的应用程序端使用它们，就像我在下面所做的那样
<meta-data
android:name="flutterEmbedding"
android:value="2" />
<meta-data android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@mipmap/ic_launcher" />
<meta-data
android:name="com.google.firebase.messaging.default_notification_channel_id"
android:value="channel_id_13"/>
在你的清单应用程序标签中记住添加相同的频道 ID
android:value="channel_id_13"
现在在我们的代码中，我们可以创建支持后台和前台的通知是
Future<void> foregroundNotificatioCustomAuddio(RemoteMessage payload) async {
final initializationSettingsDarwin = DarwinInitializationSettings(
defaultPresentBadge: true,
requestSoundPermission: true,
requestBadgePermission: true,
defaultPresentSound: false,
onDidReceiveLocalNotification: (id, title, body, payload) async {
return;
},
);
final android = const AndroidInitializationSettings('@mipmap/ic_launcher');
final initialSetting = InitializationSettings(
android: android, iOS: initializationSettingsDarwin);
localNotifications.initialize(initialSetting,
onDidReceiveNotificationResponse: (_) {
onSelectNotification(json.encode(payload.data));
});
final customSound = 'app_sound.wav';
AndroidNotificationDetails androidDetails =
const AndroidNotificationDetails(
'channel_id_14',
'channel.name',
importance: Importance.max,
icon: "@mipmap/ic_launcher",
playSound: true,
enableVibration: true,
timeoutAfter: 10000,
sound: RawResourceAndroidNotificationSound('app_sound'),
);
DarwinNotificationDetails iOSDetails = DarwinNotificationDetails(
sound: customSound,
);
final platformChannelSpecifics =
NotificationDetails(android: androidDetails, iOS: iOSDetails);
global.sp = await SharedPreferences.getInstance();
if (global.sp!.getString("currentUser") != null) {
await localNotifications.show(
10,
payload.notification!.title,
payload.notification!.body,
platformChannelSpecifics,
payload: json.encode(payload.data.toString()),
);
}
}
final localNotifications = FlutterLocalNotificationsPlugin();
现在从
打电话 FirebaseMessaging.onMessage.listen((RemoteMessage message) async {
NotificationHandler()
.foregroundNotificatioCustomAuddio(message);
await FirebaseMessaging.instance
.setForegroundNotificationPresentationOptions(
alert: true, badge: true, sound: true);
}
对于背景，现在 firebase 自动处理通知，现在请记住在您的 android/app/src/main/res/raw/app_sound.wav 中添加 app_sound.wav 格式铃声，这样它就可以工作了，我已经在 android 9 和 android 10 中测试了这些
