Preferences Xamarin.Essentials - First time check if empty?

Question

I am working with Xamarin.Forms and I am trying to check if the preferences is empty or null after launching the app. Something like this

InitializeComponent();
if (Preferences.ismpty || Preferences == null)
{
MainPage = new GamerTagPage();
}
else
{
MainPage = new HomePage();
}

You can use

var IsExist = Preferences.ContainsKey("YourKey")

to know if YourKey exists or no, and for the value you can check it with:

string returnedValue = Preferences.Get("YourKey", string.Empty)
if (string.IsNullOrEmpty(returnedValue))
   MainPage = new GamerTagPage();
else
   MainPage = new HomePage();
