How can I use the existing firebase-ios-sdk dependency in my native swift code?

Question

I am working on a Flutter app that uses the FlutterFire firebase_messaging package.

I need to add delivery reports to my app, but the FlutterFire library does not support this.

So I must implement this native swift code.

But for this code to compile I must add the firebase-ios-sdk package to my 'Runner' project.

When building I now get the error...

Error (Xcode): redefinition of module 'Firebase'

Because both my Runner project and the FlutterFire dependency are both including the firebase-ios-sdk.

How can I import FirebaseMessaging in native swift code, while using the firebase-ios-sdk dependency that FlutterFire already imports?

If I try to add a library dependency from the existing flutter dependency (I go to General > Library Dependency > select "Pods > firebase_messaging"), the swift code is not able to resolve the 'import FirebaseMessaging' statement.

this works for me:

add your firebase package to pubspec.yaml

such as :

  firebase_messaging: ^11.2.14

after that if you want to add "this native swift code" implementation you must just import below to AppDelegate file:

import Firebase
import FirebaseMessaging

and

Messaging.serviceExtension().exportDeliveryMetricsToBigQuery(withMessageInfo:request.content.userInfo)

instead of

Messaging.extensionHelper()
      .exportDeliveryMetricsToBigQuery(withMessageInfo:request.content.userInfo)
  }
