Firebase Push Notification in Flutter when App KILLED: A Complete Guide

In the world of mobile app development, implementing push notifications is crucial for maintaining user engagement. However, developers often face challenges with Firebase push notifications, particularly when the app is in a killed state. This article aims to help you solve the problem of push notifications not redirecting users to the intended page when the app is closed. Let's dive into the specifics of how this issue occurs and how to effectively manage it.

Understanding the Problem

When dealing with push notifications in Flutter using Firebase, it's essential to know how your app behaves in various states:

Background Mode: When the app is running in the background, tapping on a push notification typically redirects the user to the specified page seamlessly.

Killed State: When the app is entirely closed, tapping a push notification may only open the app instead of directing the user to the desired page, which can be frustrating for users.

This behavior raises an important question: How can we ensure that tapping on a push notification takes the user to the right location, even when the app was previously killed?

Solution: Handling Notifications When the App is Killed

The key to solving this problem lies in using the FirebaseMessaging.instance.getInitialMessage() method. This method allows your app to retrieve the message that initiated the app launch and, subsequently, navigate to the appropriate screen.

Step-by-Step Implementation

Here’s a clear breakdown of how you can implement this solution in your Flutter app:

Initialize Firebase Messaging: Make sure your Firebase Messaging is properly configured within your app.

Retrieve the Initial Message: Use the getInitialMessage() method to fetch the push notification that opened the app.

Configure Push Notifications: To set up your push notifications, you typically need to handle both foreground and background notifications. Ensure you have this configuration in place to effectively manage incoming messages:

Additional Tips

Ensure your app has the necessary permissions to receive notifications, which can be done by requesting user permissions explicitly.

Test your app thoroughly to confirm the behavior in both background and killed states to ensure a smooth user experience.

Conclusion

Handling Firebase push notifications when your Flutter app is killed can be challenging, but by using the FirebaseMessaging.instance.getInitialMessage() method, you can provide a better user experience by seamlessly navigating your users to the correct screen. Implement these steps in your application and see the difference for yourself! If you encounter any issues or have further questions, feel free to reach out or leave a comment below. Happy coding!
