Flutterfire: [firebase_messaging ] iOS: Notification Service Extension fails to compile

[kroikie]

Steps to Reproduce

I created a new flutter project in IntelliJ, followed the instructions in the firebase_messaging readme for both android and iOS integration.

I copied the main.dart from the example

at this point everything works as intended, and I can build the project in IntelliJ, it runs, and receives notifications.

I am now trying to use the iOS Notification Service Extension in order to change notification content before displaying it as described here

I opened ios/Runner.xcworkspace in Xcode and followed the instructions at the previous link to set up the Notification Service. As soon as this is done the project no longer compiles in IntelliJ. (It does compile and run as intended through Xcode)

Logs

Flutter Run

The part of the logs that stand out to me is this bit:

The rest of the log is here but I don't think that the notification service needs to be linking all of these libraries and frameworks. I checked the build settings in Xcode, and the notification service isn't set to link anything.

flutter analyze shows no issues found.

Hey all 👋

As part of our roadmap (#2582) we've just shipped a complete rework of the firebase_messaging plugin that aims to solve this and many other issues. We now have a documentation section specifically for setting up the notification extension to handle images. If you spot any issues please propose a change to the docs via a PR (there's an Edit button on the bottom of every page).

If you can, please try out the dev release (see the migration guide for upgrading and for changes) and if you have any feedback then join in the discussion here.

Given the scope of the rework I'm going to go ahead and close this issue in favor of trying out the latest plugin.

Thanks everyone.
