How to add Google.play.services.maps for using map ?

Hi everyone !

When I wanted to use maps in my application, I applied this documentation;

https://docs.microsoft.com/tr-tr/xamarin/android/platform/maps-and-location/maps/maps-api

Everything on the ios side works very nicely. But I can't install it on android side because Visual Studio won't let me install google.play.services.maps in the nuget package manager.

How can i solve it ?

Please Help !!!
