In my Flutter application, the PUSH notifications are working for Android but for IOS I'm not getting the notification alert but it prints the notification in the console from onMessage method.
Following is my command & output.
curl -X POST --header "Authorization: key=<API_KEY>" \
--Header "Content-Type: application/json" \
https://fcm.googleapis.com/fcm/send \
-d "{\"to\":\"<DEVICE_TOKEN>\",\"notification\":{\"body\":\"Testing\"},\"priority\":10}"
The output for IOS is:
{"multicast_id":9037043763539529381,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:158620223403259%62c34b3562c38b95"}]}
Following is the code block that gets executed when the notification received.
_firebaseMessaging.configure(
onBackgroundMessage: null,
onMessage: (Map<String, dynamic> message) async {
// app int he foreground
print('This works on IOS and Android both');
},
onResume: (Map<String, dynamic> message) async {
// App is in the background
print('This works on IOS and Android both');
// But no notification alert shown to the user to click (android everything works fine)
},
onLaunch: (Map<String, dynamic> message) async {
// app terminated
print('This works on IOS and Android both');
// But no notification alert shown to the user to click But no notification alert shown to the user to click (android everything works fine)
},
);
Following is my Xcode image that shows the Push Notification capabilities are added.
Any help will be appreciated...
You have to download the apn key from apple, follow this thread step by step.
I added This line in the "AppDelegate.swift" inside didFinishLaunchingWithOptions method and it solved my issue:
if #available(iOS 10.0, *) { UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate }
// I found this in the documentation of the plugin, hopefully, it solves your issue!

I am using awesome notifications in Flutter to show local notifications. My plan is to have an action button in a notification, which changes some values in the shared preferences in the background (without opening the app) when pressed. Is this even possible to do?
I tried using onActionReceivedMethod-listener and getInitialNotificationAction-method in my main function after initializing awesome notifications:
AwesomeNotifications().setListeners(onActionReceivedMethod: (action) async{
print(action.body);
});
// OR
ReceivedAction? receivedAction = await AwesomeNotifications().getInitialNotificationAction(
removeFromActionEvents: false
);
if (receivedAction?.body != null){
print(receivedAction.body);
}
Both of them worked (separetly used) only when the app had already started, but they also gave this error:
Awesome Notifications: A background message could not be handled in Dart because there is no dart background handler registered. (BackgroundService:58)
But how I could get it working when the app is not opened? Can I create a backgroung handler without Firebase, or is there some other way to achieve this?
Here is my code, how I create the notification:
static Future<void> createSimpleNotification() async {
await AwesomeNotifications().createNotification(
content: NotificationContent(
id: 1,
channelKey: 'important_channel',
title: 'Title',
body: 'Test',
largeIcon: 'asset://assets/iconPhoto.png'),
actionButtons: [
NotificationActionButton(
key:'key',
label: 'label',
actionType: ActionType.SilentBackgroundAction)]
);
}
I found the answer from here: Cannot find AwesomeNotifications().actionStream
I implemented it like this:
#pragma("vm:entry-point")
Future<void> _onActionReceivedMethod(ReceivedAction action) async {
print('It works');
}
And it worked both when the app was in the background or in the foreground.
i hope you're doing good. I'm trying to solve one problem: everything woks fine, the notifications works fine on iOS but when i try to execute a code ( showDialog ) for the notification it doesnt works. I'm using onSelectedNotification: function to execute something, in Android it works perfectly but in iOS it's just not opening. Follow the initState
FirebaseMessaging.onMessage.listen((RemoteMessage message) { RemoteNotification? notification=message.notification;
AndroidNotification? android=message.notification?.android;
if(notification!=null && android!=null){
fltNotification.show(
notification.hashCode, notification.title, notification.
body, generalNotificationDetails);
}
});
FirebaseMessaging.onMessageOpenedApp.listen((RemoteMessage message) {// I've tried to use the function here too but it not works
});
Follow the configs for HomePage:
var androiInit = AndroidInitializationSettings('#mipmap/ic_launcher');//for logo
var iosInit = IOSInitializationSettings();
IOSNotificationDetails(presentAlert: true, presentBadge: true, presentSound: true);
var initSetting=InitializationSettings(android: androiInit,iOS:
iosInit);
flutterLocalNotificationsPlugin.initialize(initSetting, onSelectNotification: onSelectNotification);
And i'm using this onSelectNotification on flutterlocalnotificationsplugin to run my function ( showDialog ) but in IOS it not works. What can i do? Am I missing something?
I use the Firebase Cloud Messaging (FCM) in my Flutter project. The following packages:
firebase_messaging: ^8.0.0-dev.15
flutter_local_notifications: ^4.0.1+2
I know that I can handle click on push-notification when app is in background in the following way:
FirebaseMessaging.onMessageOpenedApp.listen((RemoteMessage message) {
//TODO
});
and it works fine, but how to handle click on push-notification when application is in foreground? Can't find in the documentation as well. Could you please help me. Thanks in advance.
you can set the callback function on initializing
await flutterLocalNotificationsPlugin.initialize(
const InitializationSettings(
android: initializationSettingsAndroid,
iOS: initializationSettingsIOS,
),
onSelectNotification: handleClickNotification,
);
handleClickNotification(String? payload) {
//your code
}
Use this dependency when the app is in foreground- https://pub.dev/packages/flutter_local_notifications
Edit
FirebaseMessaging.onMessageOpenedApp.listen((RemoteMessage message) {
//TODO
});
You are already using this code for when the app is in background. See that you are using onMessageOpenedApp. For firing the message when in foreground you can use onMessage. Example-
FirebaseMessaging.onMessage.listen((message) {
LocalNotificationService.display(message);
});
I'm developing a delivery app, when the client orders something i want the supplier app to open up on screen with 2 buttons to accept or decline the order.
its easy to do when the supplier clicks the notification (onLaunch and onResume configuration), but i want it to happen without their interaction.
Something like when someone calls you on whatsapp or FB messanger.
is this achievable ? couldnt find such a thing in flutter.
https://pub.dev/packages/flutter_local_notifications
AndroidNotificationDetails(
'full screen channel id',
'full screen channel name',
'full screen channel description',
priority: Priority.high,
importance: Importance.high,
fullScreenIntent: true),
this will open app for android
Note: This old way for implementing the the FCM Notification,
As for the the Documentation, Notification come your app, either it is in foreground or background.
But in these case of Background: A notification is delivered to the device's system tray and the data payload is delivered in the extras of the intent of your launcher Activity.
Case of Foreground: You can navigate to any screen. with help of
final FirebaseMessaging fcmMessaging = FirebaseMessaging();
fcmMessaging.configure(
onMessage: (Map<String, dynamic> message) async {
print("onMessage: $message");
},
onLaunch: (Map<String, dynamic> message) async {
print("onLaunch: $message");
// your code
},
onResume: (Map<String, dynamic> message) async {
print("onResume: $message");
},
);
New way : https://stackoverflow.com/a/73221621/5197656
Take a look at the firebase_messaging docs where it explains how to setup background messages on Optionally handle background messages
I am developing a mobile app and I want to open a splash screen or open startup page when I receive a notification.
Currently, I am using the following code
static Future<dynamic> myBackgroundMessageHandler(
Map<String, dynamic> message) async {
print("_backgroundMessageHandler");
_callBgHandler = 1;
if (message.containsKey('data')) {
// Handle data message
final dynamic data = message['data'];
print("_backgroundMessageHandler: ${data}");
DeviceApps.openApp("com.example.my_flutter_app");
}
if (message.containsKey('notification')) {
// Handle notification message
final dynamic notification = message['notification'];
print("_backgroundMessageHandler notification: ${notification}");
}
return Future<void>.value();
}
and the following error displayed
Attempt to invoke virtual method 'android.content.pm.PackageManager
android.app.Activity.getPackageManager()' on a null object reference
The last one month tried but no luck. If anyone knows let me share the code from flutter dart language
But Button press event it will work.
RaisedButton(
onPressed: () {
DeviceApps.openApp("com.example.my_flutter_app");
},
child: Text("Open App")
)
Default applications like a map, chrome, play store, email app, etc... All are open with no issue but the external app does not open notification background function.
