Flutter Firebase Messaging Not working on IOS when app running in background or closed

Question

I have configured firebase Cloud Messaging with flutter Notification are working in foreground. but not working when running in background or app is killed.

Following steps are done.

Generated app ID and push Key in https://developer.apple.com/account/resources/certificates/
Added info.plist to ios/Runner folder
Turned on Push capabilities
Uploaded APNS certificate to Firebase console
Added lines in AppDelegate.swift

Also tried to remove following line as suggested on Flutter Firebase Cloud Messaging - Notification when app in background but it is still not working.

if (@available(iOS 10.0, *)) { [UNUserNotificationCenter currentNotificationCenter].delegate = (id) self; }

Flutter Doctor

[✓] Flutter (Channel beta, v1.12.13+hotfix.6, on Mac OS X 10.14.5 18F132, locale en-IN)

[✗] Android toolchain - develop for Android devices

    ✗ Unable to locate Android SDK.

      Install Android Studio from: https://developer.android.com/studio/index.html

      On first launch it will assist you in installing the Android SDK components.

      (or visit https://flutter.dev/setup/#android-setup for detailed instructions).

      If the Android SDK has been installed to a custom location, set ANDROID_HOME to that location.

      You may also want to add it to your PATH environment variable.



[✓] Xcode - develop for iOS and macOS (Xcode 11.3)

[✓] Chrome - develop for the web

[!] Android Studio (not installed)

[✓] Connected device (3 available)

One thing I noticed that , when app is installed first time it is not asking me to check if the I allow the app to send push notification.

My code is having following lines on page after login page.

_firebaseMessaging.requestNotificationPermissions(
        const IosNotificationSettings(sound: true, badge: true, alert: true));
    _firebaseMessaging.onIosSettingsRegistered
        .listen((IosNotificationSettings settings) {
      print("Settings registered: $settings");
    });

Also cross checked that all following setting are ticked.

I guessing you are using the local_notification with this package, it's a common issue conflict between local_notification and this package — Mahmoud Niypoo, Apr 23 '20 at 01:39

After a long time searching for a fix, this solved the problem for me:

In your info.plist:

 FirebaseAppDelegateProxyEnabled: false

Add this to your AppDelegate:

override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

   Messaging.messaging().apnsToken = deviceToken
   super.application(application, didRegisterForRemoteNotificationsWithDeviceToken: deviceToken)
 }

what you have added inside AppDelegate can you share your code? – Krunal Darji Jul 20 '20 at 19:04

Only this method, you just need to place it inside the AppDelegate class and import Firebase – dcg Jul 20 '20 at 21:01
Thank you @dcg your solution worked for me. This should been in the firebase_messaging documentation. – dileep Aug 28 '20 at 03:24
What are the imports for the `AppDelegate` changes? – yardstick17 Mar 03 '21 at 13:50

don't forget to add "import FirebaseMessaging" in AppDelegate – Muhammad Adil Mar 03 '21 at 19:22
hello After add the code to appdelegate i cant run it on simulator.. is given error – Gbenga B Ayannuga Aug 06 '21 at 14:28
There's already a function called application, should I copy the 2 lines inside the function body? – Ahmed Nabil Jun 09 '22 at 13:52
Exactly, just use it inside this function. – dcg Jun 09 '22 at 17:57
This must be marked as the right answer, thans so much. I spend hours trying to solve this, and is missing the AppDelegate.swift edition in the Google´s official documentation – isaacfi Dec 01 '22 at 16:21

My Solution is as follows and it works.

publspec.yaml

firebase_messaging: ^6.0.9

Remove following line from ios/runner/AppDelegate.m or ios/runner/AppDelegate.swift if used.

if (@available(iOS 10.0, *)) {
  [UNUserNotificationCenter currentNotificationCenter].delegate = (id<UNUserNotificationCenterDelegate>) self;
 }

in Dart code use provisional false, Should get pop up to confirm on notification.

myFirebaseMessagingService.requestNotificationPermissions(
        const IosNotificationSettings(
            sound: true, badge: true, alert: true, provisional: false));

In Xcode Following Push notification along with background Fetch and remote notification.

Make sure that Push Notifications & Background Mods Capabilities were enabled in the All tab under Signing & Capabilities, not only in Profile like what I was doing.

There is nothing to change or add in AppDelegate and Info.plist, just provide the correct notification payload and it will trigger:

sample valid payload

{
  "to" : "my_fcm_token",
  "notification" : {
 "body" : "sample body",
 "OrganizationId":"2",
 "content_available" : true,
 "mutable_content": true,
 "priority" : "high",
 "subtitle":"sample sub-title",
 "Title":"hello"
 },
  "data" : {
    "msgBody" : "Body of your Notification",
    "msgTitle": "Title of your Notification",
    "msgId": "000001",
    "data" : "This is sample payloadData"
  }
}

I have similar issue, I need to revoke the old key, create a new authentication key and upload again to make it works:

I managed to get my app working and listening to onBackgroundMessage on Android (I just removed the notification object from my payload, leaving only the data object).

    final data = {
  "registration_ids": userToken,
  "click_action": "FLUTTER_NOTIFICATION_CLICK",
  "priority": "high",
  "collapse_key": "type_a",
  "data": {
    "click_action": "FLUTTER_NOTIFICATION_CLICK",
    "other_data": "any message",
    "title": 'NewTextTitle',
    "body": 'NewTextBody',
    "priority": "high",
    "click_action": "FLUTTER_NOTIFICATION_CLICK",
  },
};

The question is to make it work on IOS. not android, therefore this answer is invalid — Gino, Jan 13 '21 at 14:12

In my case, I solved it as below.

Complete the tutorial guide and try the following:

Edit : iOS/Flutter/AppFrameworkInfo.plist
- <key>CFBundleIdentifier</key> <string>{bundleIdentifier}.flutter</string>
- {bundleIdentifier} is: Enter the Bundle name set at https://developer.apple.com.
Example
- Developer.apple: com.example.app
- xcode BundleIdentifier : com.example.app
- iOS/Flutter/AppFrameworkInfo.plist : com.example.app.flutter
Test environment :
- Firebase_core: ^0.4.5
- Firebase_messaging: ^6.0.16
(Additional) When sending from your server or page
- Please set the "notification" item.

which tutorial? Can you please complete it ? – M. A. Dec 12 '20 at 19:23 — M. A., Dec 12 '20 at 19:23

After spending couple of days, finally i found a solution. Please follow the below steps carefully

Add this line to your info.plist FirebaseAppDelegateProxyEnabled : NO

Add following code to the AppDelegate

 func application(application: UIApplication,
                 didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    Messaging.messaging().apnsToken = deviceToken
}

In order to activate background handling in iOS, the following fields need to be included to the notification request:

"content_available": true

As a result, testing this functionality through the Firebase console is not possible. To achieve this, notifications must be sent using Postman.

Add the following parameters to the headers of the request

Content-Type : application/json

Authorization: key = your_server_key

Send notification though the Postman

request url :

https://fcm.googleapis.com/fcm/send

request body :

{
  "to" : "your_fcm_token",
  "notification" : {
 "body" : "sample body",
 "content_available" : true,
 "priority" : "high",
 "Title":"hello"
 }
}

This works for me !
