Hello,
I am trying to send Push Notification to our Flutter App using FCM. While it is working fine with Android, it does not work with iOS. I believe the problem is that Sendbird does not send “content\_available” parameter in the notification payload. Due to this the onBackgroundMessage callback does not run, which in turn does not show the notification in the App. Please be informed that I am using flutter\_local\_notifications along with firebase\_messaging plugins.
I want to know if someone else is also facing the same problem. Also, let me know if there is a better way to implement this feature.
Thank You.

Hey @Arslan, Could you please send your app ID to me via DM (Direct Message)?

I am facing the same problem. I can get it to work with flutter\_apns, but would rather use firebase\_messaging as the flutter\_apns package is not updated. Did you manage to resolve this? Would be great if you could share your tips

Hello @Arslan you need to upload apple certificate on sendbird dashboard and use APNS token to register in order to make push notification works on iOS device.

I think latest firebase messaging supports a feature for APNS token. You are no longer need to use flutter\_apns to register APNS token

We are also having issues with push notifications to Flutter+iOS in the same way that @Arslan describes. [This issue on github](https://github.com/firebase/flutterfire/issues/4300) goes into this, and [one commenter suggests patching the library](https://github.com/firebase/flutterfire/issues/4300#issuecomment-916883580) by removing two checks for gcm.message\_id. @Arslan, did you ultimately solve the issue, and if so, was it by patching the library in this way? @Woo, is there more insight you can provide on firebase messaging’s support for APNS tokens? Thank you, everyone!

@Woo
Having same issue for this.
Push notification does come in as APNs but I need the push to come as FCM not APNs.
so FCM’s onBackgroundMessage/onMessage.listen/onMessageOpenedApp.listen method’s cannot catch Sendbird’s push.
How do I have to solve this?

Hello guys, we are facing same problem. IS there any solution available from Sendbird side or not?

We disabled Sendbird Push Notifications feature and used Sendbird Webhooks feature and send the notifications from our own backend.

Hello,
We have the same issue.
On iOS`FirebaseMessaging.onMessage` is not triggered.
Because of this, we cannot push the app to open the chat screen route.
This works on Android, but not iOS.
**EDIT:**
Okay so I fixed it manually.
What I did was update `AppDelegate.swift` to manually trigger the `onMessage` and `onMessageOpenedApp` events in Flutter.
This is my updated `AppDelegate.swift`:
```auto
import UIKit
import Flutter
import Firebase
import GoogleMaps
import flutter_local_notifications
@main
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
FirebaseApp.configure() // This must be done before GeneratedPluginRegistrant
FlutterLocalNotificationsPlugin.setPluginRegistrantCallback { (registry) in
GeneratedPluginRegistrant.register(with: registry)
}
GeneratedPluginRegistrant.register(with: self)
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
}
// Handle notification tap when app was closed
if let remoteNotification = launchOptions?[.remoteNotification] as? [AnyHashable: Any] {
handleNotificationTap(remoteNotification)
}
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
override func application(
_ application: UIApplication,
didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void
) {
#if DEBUG
print("APNs Push Notification Received: \(userInfo)")
#endif
if let controller = window?.rootViewController as? FlutterViewController {
let channel = FlutterMethodChannel(
name: "plugins.flutter.io/firebase_messaging",
binaryMessenger: controller.binaryMessenger
)
let dictionary = convertToDictionary(userInfo)
// If app is in foreground, show `onMessage`
if application.applicationState == .active {
channel.invokeMethod("Messaging#onMessage", arguments: dictionary)
} else {
// App is in background or inactive, handle with userNotificationCenter
}
}
completionHandler(.newData)
}
// Detect when user taps notification in the foreground
override func userNotificationCenter(
_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: @escaping () -> Void
) {
let userInfo = response.notification.request.content.userInfo
#if DEBUG
print("Notification Tapped (Foreground): \(userInfo)")
#endif
handleNotificationTap(userInfo)
completionHandler()
}
// Handle Notification Taps (Works for Background & Foreground)
private func handleNotificationTap(_ userInfo: [AnyHashable: Any]) {
let convertedData = convertToDictionary(userInfo)
#if DEBUG
print("Converted Notification Data (Before Sending to Flutter): \(convertedData)")
#endif
if let controller = window?.rootViewController as? FlutterViewController {
let channel = FlutterMethodChannel(
name: "plugins.flutter.io/firebase_messaging",
binaryMessenger: controller.binaryMessenger
)
let finalPayload: [String: Any] = ["data": convertedData]
channel.invokeMethod("Messaging#onMessageOpenedApp", arguments: finalPayload)
}
}
// Convert userInfo (NSDictionary) to Flutter-readable dictionary
private func convertToDictionary(_ userInfo: [AnyHashable: Any]) -> [String: Any] {
var dictionary = [String: Any]()
for (key, value) in userInfo {
if let keyString = key as? String {
dictionary[keyString] = unwrapValue(value)
}
}
return dictionary
}
// Recursively unwrap nested dictionaries and arrays
private func unwrapValue(_ value: Any) -> Any {
if let dict = value as? [AnyHashable: Any] {
return convertToDictionary(dict) // Recursively convert dictionary
} else if let array = value as? [Any] {
return array.map { unwrapValue($0) } // Recursively convert array
} else {
return value // Return primitive types as is
}
}
}
```
