Not sure what is up, but after rolling back to older firebase, it seems to work.

Rolled back to:
firebase_core: ^1.0.1
firebase_analytics: ^7.1.1

[Danis96]

Do we have solution for this?
I have the same issue, I tried @leossmith answer but it don't work

[danielseow-simplify]

having the same issue as well after I updated Flutter to 2.2.0 I think
Edited: roll back to Flutter 2.0.6 still the same issue

firebase_core: ^1.0.1
firebase_analytics: ^7.1.1

even tried this also not working

[leossmith]

I have not figured out a solution after all. Looks like it works some times when others it doesnt. It is also very strange as it was working up to 3-4 days ago with the latest versions of all.

I tried migrating to onesignal 3 beta but i still get the same issue. It leads me to suspect some problem/conflict with google services. For now I had to release an update without the one signal plugin and wait for a fix.

[Danis96]

This was what solved the problem for me:

pubspec.yaml :

dependency_overrides:
crypto: ^2.1.5
archive: ^2.0.13
firebase_dynamic_links: ^0.6.0
firebase_core: ^0.5.2
quiver: ^3.0.0
geolocator_platform_interface: ^2.0.2
plugin_platform_interface: 1.0.2

quiver: ^3.0.0
geolocator_platform_interface: ^2.0.2
plugin_platform_interface: 1.0.2

Was that just downgrading firebase? which version of onesignal are you using?

the downgrade of firebase version affects too many other plugins that I am currently using on my project... so it is not working for me

[Danis96]

@leossmith I use onesignal_flutter: ^2.6.3

I just downgrade the firebase dependecies, you can maybe check the source code of one signal

[leossmith]

Sadly rolling back firebase to a so old version is not an option. I am starting to consider moving to Firebase Messaging instead.

[danielseow-simplify]

I just realised they committed and pushed these lines in their OneSignal-Android-SDK, therefore, I believe it is really an issue from the Android SDK plugin, so we have to wait for the fix from them.

Yes it looks like it is only affecting android as iOS works ok.

Looks like Flutter sdk is way outdated compared to native.

[leossmith]

It looks like this was a common issue in Android SDK and was fixed in newer versions:

[danielseow-simplify]

They just released a new version Android SDK that fix this issue~!
I've manually modified the OneSignal Android SDK version in OneSignal Flutter SDK to 4.4.0 and it is working now~!

try to look for the OneSignal dependency in your project and do according to the image shown. Good luck

[leossmith]

Thank you @danielseow-simplify . This solved my issue (on which i have spent like 5 hours trying to figure out how to fix it). I hope OneSignal will update their flutter sdk soon

I tried updatig the version for OneSignal Android SDK, but I get build errors now. Some of the errors:

C:\Users\user\AppData\Local\Pub\Cache\hosted\pub.dartlang.org\onesignal_flutter-2.6.3\android\src\main\java\com\onesignal\flutter\OneSignalOutcomeEventsController.java:4: error: cannot find symbol

I think it is better to upgrade your OneSignal Flutter to the latest beta version, also you will need to change the code for OneSignal in your project
Please refer to this link https://documentation.onesignal.com/docs/step-by-step-flutter-2x-to-300-upgrade-guide

I have the same problem. Can someone help? None of the above mentioned solutions are working for me.

Update to beta4 version, flutter clean, then rebuild. It should fix it.

[jkasten2]

This was due to a compatibility issue with Firebase FCM 22.0.0. I can confirm the issue has been fixed in the 3.0.0-beta4 Release and is now also included in the 2.6.4 Release we just released today.

This is the same issue as #402
