Flutter FCM notification onTap callback not working when app is in foreground, works in background. This issue can be frustrating for developers and users alike.

🛑 Root Causes of the Error

  • When a notification is received in the foreground, the OS takes control and opens the app. The onTap callback may not be triggered because the OS has already handled the tap event.

🚀 How to Resolve This Issue

Method 1: Use the notification listener

  1. Step 1: Create a Firebase Cloud Messaging (FCM) notification listener in your app. This listener will be triggered when a notification is received.

Method 2: Use the Android or iOS platform's built-in notification handling

  1. Step 1: In Android, use the NotificationCompat API to handle notifications. In iOS, use the UNNotificationHandlerDelegate protocol.

💡 Conclusion

By implementing one of these methods, you should be able to resolve the issue and get your onTap callback working even when the app is in foreground.
