FFImageLoading define _authService

Hi there,

i try to implement the plugin "ffimageloading" in a little test-app, but because I'm a rookie, there is one problem with the authentication, I cannot fix.

Here is the Link of the plugin (only the part of authentication): https://github.com/luberda-molinet/FFImageLoading/wiki/Authentication-Support

So like there is written I edited

ImageService.Instance.Initialize(new Configuration
    HttpClient = new HttpClient(new AuthenticatedHttpImageClientHandler(_authService.GetToken))

in my AppDelegate, created a class, copied the snippet and added unsing-directories.

My problem is, that there is no "_authService" defined. But how can I define it? Any hints?

    This class AuthenticatedHttpImageClientHandler just helps you add a user token in your header when you query a request. You need to define your own service class. This is a sample for you referring to:

    public class AuthenticationService
        Func<Task<string>> getToken;
        public Func<Task<string>> GetToken
            get { return getToken; }
        public AuthenticationService()
            getToken = async () =>
                return "UserToken";

    Sorry, but I don't understand this.

    I have username, password and domain and want to put it into a Token so that FFImageLoading can use it.

    I had a similiar problem with an app for my website. By the way... Please give me an honest feedback about the website and any suggestions of what could be done to make it better. http://under-the-open-sky.com. I've been working on it for a very long time, can you test it out for me?
