MT2101: Can't resolve the reference 'System.Void Firebase.CloudMessaging.Messaging

The Issue started with a Plutin XML error that was resolved by saving my GoogleService.Plist in Xcode then adding it to the project. The error then progress to ->

 'System.Void Firebase.Analytics.App::Configure()', referenced from the method 'System.Void Plugin.FirebasePushNotification.FirebasePushNotificationManager/d__31::MoveNext()' in 'Firebase.Analytics, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. Insider.iOS

Which I Noticed I had a Missing Dependency Which I installed. Then led me to:

Deployment to Device
