Resolving the onMessageOpenedApp Issue with Freshchat on iOS: A Complete Guide

If you've ever experienced issues with integrating Freshchat and Firebase Cloud Messaging (FCM) specifically on iOS, you're not alone. Many developers have come across the frustrating scenario where the onMessageOpenedApp functionality does not trigger when tapping on push notifications that contain deep links. This guide is designed to help you resolve this issue effectively.

Understanding the Problem

As a developer, encountering bugs with third-party libraries can be challenging, particularly when they involve big features like push notifications. In this instance, the problem arises when:

Platform: The issue is limited to iOS devices.

Functionality: The onMessageOpenedApp function does not get called when a user interacts with a push notification containing a deep link.

This problem can lead to a poor user experience, as notifications that are meant to drive engagement may simply fail to do so.

Identifying the Cause

After researching and troubleshooting, it was discovered that the issue stems from how the Freshchat library pertains to the native iOS delegate methods. Specifically, the library overloaded the userNotificationCenter methods, which caused the onMessageOpenedApp event not to be triggered under some circumstances.

The Solution: Update Your AppDelegate.swift

To resolve this issue, you need to modify the AppDelegate.swift file in your Flutter project. By calling the super implementation of the userNotificationCenter methods, you allow both the Freshchat functionality and the required Firebase functionality to coexist.

Here’s How to Implement the Fix:

Open your AppDelegate.swift file: This file contains the configurations needed for your iOS app.

Implement the following code:

Key Changes Explained

Super Calls: By calling super.userNotificationCenter, you ensure that the Firebase mechanisms to open messages when they are tapped are executed properly.

Freshchat Handling: The conditions check if the notification is a Freshchat one and handle it accordingly. If not, it defers to the original handling by calling the superclass's implementations.

Conclusion

By implementing these changes, you should see the onMessageOpenedApp function work correctly when your users tap on notifications in iOS. This straightforward fix will greatly improve the functionality of your application and enhance the push notification experience for users.

Feel free to share your feedback or issues, and I'm hopeful that this solution will be helpful to you and any developers facing this challenge in the future!
