firebase_messaging not working if include flutter_local_notifications package on iOS

[ishakdas]

Hello to everyone
I was able to send data notification in the background via android but I think there is a problem for ios.
Is this Problem a solved issue or is it still going on?

Hi @ishakdas
flutter_local_notifications is a 3rd party plugin,
if you are experiencing problems with that you may want to open an issue in the dedicated github.

If you are experiencing issues with firebase_messaging
please provide your flutter doctor -v
and your flutter run --verbose.
Also, to better address the issue, would be helpful
if you could post a minimal code sample
or the steps to reproduce the problem.
Thank you

The firebase plug-in works alone but does not work with the flutter_local_notifications plug-in.
It doesn't work in the background.
The application works while it is open.

This is an old and ongoing issue with the local_notifications plugin. There are more details there. It has something to do with both of the plugins registering on the same channel or something. This issue should be closed here and you can follow the issue on their side.

Just saw this but it wasn't an issue with the flutter_local_notifications plugin. Changes were made in the Flutter engine to allow multiple notification plugins to register themselves. flutter_local_notifications was updated to accomodate for this but the code changes for firebase_messaging hadn't been done. There was an issue to track that on this repository at #1455. The PR (#1829) I created to update the firebase_messaging plugin to resolve this issue was just recently merged in and now needs the new version of the plugin to be released
