Use this sample as a way to understand how to Get, Post, and Delete to a Firebase Realtime Database in a Xamarin Forms app.
This sample uses the NuGet FirebaseDatabase.net: https://www.nuget.org/packages/FirebaseDatabase.net/
Note: This app will not run because the Config folder is missing. Use your own Firebase values for the Firebase Client and Auth.
public class ConfigFirebase
{
public static string FirebaseClient = "your firebase DB url";
public static string FrebaseSecret = "your app secret";
}
