I am setting a flutter project on Mac M3. I am getting the following error

Solution

  • For me, the issue is because of the FBAudienceNetwork. I have facebook_app_events dependency in my Flutter app.

    FBAudienceNetwork is updated recently with version 16.6.0.

    I have override the facebook_app_events from https://github.com/oddbit/flutter_facebook_app_events/tree/fix/iOS-issue-0.19.4. It is using the FBAudienceNetwork version 16.5.0

      facebook_app_events:
    git:
      url: https://github.com/oddbit/flutter_facebook_app_events
      ref: fix/iOS-issue-0.19.4

    Update:
