flutter: fcm ios push notifications doesn't work in release mode

Question

I have bound my flutter-iOS app to firebase and i'm also using firebase-messaging and cloud functions for sending notifications via subscribing to topics, i'm using the APNs push notifications key of apple developer account. when i use the option runner>flutter run main.dart in release mode to build my app on my phone, fcm notifications doesn't work anymore, while it works in development mode, anyone can help me fix this?

this is my index.json code:

const functions = require('firebase-functions');
const admin = require('firebase-admin');

admin.initializeApp(functions.config().firebase);
 
var newData;
 
exports.messageTrigger = functions.firestore.document('notifications/{notificationsId}').onCreate(async (snapshot, context) => {
newData = snapshot.data();
const payload = {
    notification: {
        title: newData.title,
        body: newData.body,
        sound: 'default'
    },
    
        data: {
      click_action: 'FLUTTER_NOTIFICATION_CLICK',
      message: newData.title,
    }

};

if (newData.language === 'english'){
    await admin.messaging().sendToTopic('english', payload);
}
else if (newData.language === 'arabic'){
    await admin.messaging().sendToTopic('arabic', payload);
}
else if (newData.language === 'kurdish'){
    await admin.messaging().sendToTopic('kurdish', payload);
}
});

hence package.json:

{
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "scripts": {
    "lint": "eslint .",
    "serve": "firebase emulators:start --only functions",
    "shell": "firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "engines": {
    "node": "10"
  },
  "dependencies": {
    "firebase-admin": "^8.10.0",
    "firebase-functions": "^3.6.1"
  },
  "devDependencies": {
    "eslint": "^5.12.0",
    "eslint-plugin-promise": "^4.0.1",
    "firebase-functions-test": "^0.2.0"
  },
  "private": true
}

Make sure Push Notification Certification you have created supports production. – Allogamy

hello, thankyou, Ihaven't distributed it in the appstore yet, just build released on my phone, does that need a certificate too? – Inkhorn

im not using push notifications certificate , im using APNS key – Inkhorn

please send me firebase cloud messaging settings page screenshot. where you added the apn – Allogamy

how do i send it? i have uploaded the apns key correctly to firebase, it works well on android debug and release as well as ios debug, the only problem is ios release mode – Inkhorn

Android doesn't need APN keys. please send a link of the screenshot – Allogamy

Are you using firebase functions? – Allogamy

yes cloud functions – Inkhorn

onedrive.live.com/… – Inkhorn

show me the package.json file of the cloud function – Allogamy

i used index.json, its int the same link – Inkhorn

The link is not working. Please edit the question and add the package.json code and index.json code. – Allogamy

added them, thankyou – Inkhorn

Answer 1

My project got the same issue. Combined two solutions I found, it finally works. (firebase_messaging 7.0.3)

As for debug mode, you don't need these.

Step 1: Edit AppDelegate.swift

import UIKit
import Flutter

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    if #available(iOS 10.0, *) {
      UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
    }
    
    GeneratedPluginRegistrant.register(with: self)

    application.registerForRemoteNotifications()

    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

Step 2: Edit ios/Runner/Info.plist. Add this:

<key>FirebaseAppDelegateProxyEnabled</key>
<string>NO</string>

I had similar issue and just adding this application.registerForRemoteNotifications() solved my problem – Jenks

Same problem application.registerForRemoteNotifications() solved my problem – Tranquillize

Answer 2

After update firebase_messaging to 7.0.0 I had the same problem. I added application.registerForRemoteNotifications() in my AppDelegate.swift and it worked!

Answer 3

I tried many ways. I did deep research, when i give up i checked my Xcode Settings and i saw under Signing&Capabilities -> Debug -> Notification added but Signing&Capabilities -> Release I didn't add. so i added capability and it worked look this

Answer 4

I have the same issue. Looks like iOS release require additional notification params

To check that notification works you could try to send message directly from the firebase console.

Cloud Messaging -> Send your first message -> Enter notification title and text -> Send test message -> Enter your device token -> Test

To obtain device token you can use print(await FirebaseMessaging().getToken());

To check release logs connect the device and open Xcode -> Window -> Devices and Simulators -> Open Console

If it works you could try to add this params:

const payload = {
 notification: {
    title: newData.title,
    body: newData.body,
    sound: 'default'
 },
 data: {
    click_action: 'FLUTTER_NOTIFICATION_CLICK',
    message: newData.title,
 },
 apns: {
    headers: { "apns-priority": "5" },
    payload: {
            aps: {
                contentAvailable: true,
                category: "NEW_MESSAGE_CATEGORY"
            }
        }
    },
};

But I'm not sure which param helps: "apns-priority" or contentAvailable.

Answer 5

You have to create appropriate certificates to enable Pushnotifcation in Release mode iOS

Note : Everything will run as expected in debug mode even if you don't have Provisional Profile Certificate. But It's mandatory in release mode

1. Apple SandBox Push service certificate
2. Provisional Profile Certificate
3. Apple Development, Distribution, Sigin Certificate all is mandatory

Follow the steps in the link : https://firebase.flutter.dev/docs/messaging/apple-integration/

Answer 6

I have same Issue, I add only one development APNs certificate to firebase and forget add product APNs certificate to firebase settings. this why ios debug work but not release

Answer 7

I faced same issue. I was using flutter_local_notifications: ^17.2.1+2 and firebase_messaging: ^14.6.8. I checked APNs key (.p8 file) was configured properly in firebase console and with debug mode push notification was working but for release mode it was not working through flutter run --release

What I found is I did directly drag and drop GoogleService-Info.plist file under Runner directory through Android studio and because of that, folder reference was not created. So I removed GoogleService-Info.plist and added through xCode with drag and drop file under Runner directory with selecting Create folder reference and it's worked!!!

Once we do this ios/Runner.xcodeproj/project.pbxproj will get changed.

This might be useful for someone who faces issue same like me.
