Welcome, please format your code correctly when you post it so people can read it.

The problem it seems, as the error states, is that geolocation is undefined, you need to inject it in your constructor like you do the NavController.

The problem I see is that geolocation is not declared as any variable within the class, you have to pass it to the constructor. You should read the documentation so that you avoid headaches.
