[firebase_messaging]: FirebaseMessaging.instance.getInitialMessage() and FirebaseMessaging.onMessageOpenedApp not being called on iOS

[andonigarcialopez]

Is there an existing issue for this?

• I have searched the existing issues.

Are you aware of the differences between iOS and Android background message handling?

• I understand that iOS and Android background messages behave differently, and I've designed my application with that in mind.

Do you have an active Apple Developer account?

• I have an active Apple Developer account.

Are you using a physical iOS device to test background messages?

• I am using a physical iOS device to test background messages.

Have you enabled "Remote Notifications" & "Background Mode" (Checking options for "Background Processing" & "Remote Notifications") in your app's Xcode project?

Have you created an APNs key in your Apple Developer account & uploaded this APNs key to your Firebase console?

Have you disabled method swizzling for Firebase in your app?

Have you requested permission from the user to receive notifications?

• I have the relevant permission to receive notifications.

Have you used the 'Console' application on your macOS device to check if the iOS device's system is throttling your background messages?

Additional context and comments

Expected behaviour of FirebaseMessaging.onMessageOpenedApp:

App is on background, tapping the notifications opens the app an executes the FirebaseMessaging.onMessageOpenedApp callback.

Problem: FirebaseMessaging.onMessageOpenedApp is not being called when the notification y tapped and the app is on background.

Expected behaviour of FirebaseMessaging.instance.getInitialMessage:

App is terminated, tapping the notifications opens the app an executes the FirebaseMessaging.instance.getInitialMessage callback.

Problem: FirebaseMessaging.instance.getInitialMessage is not being called when the notification y tapped and the app terminated.

Thanks for reporting the issue. To help us better understand and debug the problem, could you please try reproducing the issue using the latest commit from the firebase_messaging example in the official FlutterFire repository? This will help determine if the issue is specific to your implementation or if it’s a more general problem with the package.

You can find the example here:
FlutterFire Firebase Messaging Example

[andonigarcialopez]

Hi, as you asked Im using the latest commit from the firebase_messaging example in the official FlutterFire repository (main branch).

Until now I can provide the following feedback.

For android: (tested in android 11)
FirebaseMessaging.instance.getInitialMessage()

When the app is terminated and you open it tapping the push notifications you only receive the value on first time, after this the value always comes as null if you open the app taping the notification.

FirebaseMessaging.onMessageOpenedApp

When you have you app on background (not terminated) and you push the notification FirebaseMessaging.onMessageOpenedApp isn't triggered

FirebaseMessaging.onMessage

Works as intended.

For iOS (iPhone 14, iOS 18.3.2)

FirebaseMessaging.instance.getInitialMessage()

When the app is terminated and you open it tapping the push notifications the value (data) is always null.

FirebaseMessaging.onMessageOpenedApp

Works as intended.

FirebaseMessaging.onMessage

Works as intended.

HI @kirya355, I updated the feedback for iOS using the firebase_messaging package example. Thanks.

[SelaseKay]

Hi @andonigarcialopez, getInitialMessage returns a value only when the app is opened from a terminated state, as stated in the documentation. Could you confirm that your app openings are indeed from a terminated state? Also, your sample repro is quite lengthy, please trim it down to the minimal code needed to reproduce the issue.

[andonigarcialopez]

Hi @SelaseKay, I just tested it again using example in the official FlutterFire repository, getInitialMessage is not returning a value from terminated state. On Android work the first after installing the app, then stops working. On iOS never works.

You can check the code on example in the official FlutterFire repository, https://github.com/firebase/flutterfire/tree/main/packages/firebase_messaging/firebase_messaging
as im using it to test this feature right now.

For android Im testing on android 11 (Android one, no additional layers)

For iOS Im testing in an iPhone 14 ( iOS 18.3.2)

Both real devices.

I'm using Flutter version 3.29.2

Thanks!
