Cannot find 'AppsFlyerAttribution' in scope

[Icety]

Describe the bug I followed the guides on how to add DeepLinks to my Flutter application. When I add the mentioned methods in my AppDelegate.swift, I receive an error: Cannot find 'AppsFlyerAttribution' in scope. I already tried adding import AppsFlyerLib or import AppsFlyerAttribution, but without any success.

To Reproduce Steps to reproduce the behavior:

1. Follow the swift steps on https://github.com/AppsFlyerSDK/appsflyer-flutter-plugin/blob/master/doc/DeepLink.md
2. Try to run Flutter
