Solvedflutterfire 🐛 [firebase_messaging][firebase_auth] Data-only messages not received in iOS. Never fires anything in onMessage

1917

Bug report

Describe the bug
On iOS, it appears that sending a data-only message to FCM is not received at the device, even though the message is successfully sent according to FCM rest API.

This is on a real iOS device and not a simulator. Push notifications are otherwise working great - it's just data-only messages that are not doing anything in iOS. I have full functionality with onLaunch, onMessage, and onResume on iOS and Android, as long as it's a notification. Data-only is only being received on Android though.

Steps to reproduce

Note: in the following examples I've redacted the token.

This message is not received in iOS:

{
    "message": {
        "token": "---",
        "data": {
            "foo": "bar"
        }
    }
}

This one does work as expected:

{
    "message": {
        "token": "---",
        "notification": {
            "title": "test"
            "body": "test"
        },
        "data": {
            "foo": "bar"
        }
    }
}

It appears there's no way to receive data-only messages in iOS. It doesn't matter if the app is foregrounded or backgrounded- onMessage is never fired.

Expected behavior

iOS should work with data messages exactly as it does in Android.

Disabling method swizzling and using the below in my AppDelegate.swift, fingers crossed but this seems to fix it so that both auth and messaging are functioning as expected. It would be nice to use swizzling but this isn't the end of the world if this is required to make the two work.

pubspec.yaml:

  firebase_auth: ^0.18.0+1
  firebase_core: ^0.5.0
  firebase_messaging: ^7.0.0

ios/Runner/Info.plist:

<key>FirebaseAppDelegateProxyEnabled</key>
<false/>

AppDelegate.swift:

import UIKit
import Flutter
import FirebaseAuth
import FirebaseMessaging

@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
        }
        
        GeneratedPluginRegistrant.register(with: self)
        return super.application(application, didFinishLaunchingWithOptions: launchOptions)

        Auth.auth().setAPNSToken(deviceToken, type: .unknown)
        
        // Pass device token to messaging

        if ((notification["gcm.message_id"]) != nil) {
            Messaging.messaging().appDidReceiveMessage(notification)
        }
        
        return super.application(application, didReceiveRemoteNotification: notification, fetchCompletionHandler: completionHandler)
    }
    
    // https://firebase.google.com/docs/auth/ios/phone-auth#appendix:-using-phone-sign-in-without-swizzling
    override func application(_ application: UIApplication, open url: URL,
                              options: [UIApplication.OpenURLOptionsKey : Any]) -> Bool {
        // Handle auth reCAPTCHA when silent push notifications aren't available

        }
