Facebook GameRequestDialog

[treidio]

Hi,

sorry I don't know how to do pull requests, and besides my code is so amateur. :)

For IOS i got the game request dialog working, sharing it back with the project.. I don't get the alert in the destination account, but expect that's because my app isn't published or approved.

Presented at your own risk..

FacebookClientManager.cs ~line 216

    public async Task<FacebookResponse<Dictionary<string,object>>> GameRequestDialog(string message, string title = "")
    {
        _shareTcs = new TaskCompletionSource<FacebookResponse<Dictionary<string, object>>>();
        Dictionary<string, object> parameters = new Dictionary<string, object>()
        {
            {"message",message},

        };

        if (!string.IsNullOrEmpty(title))
        {
            parameters.Add("title", title);
        }
        return await PerformAction(RequestGameRequestDialog, parameters, _shareTcs.Task, FacebookPermissionType.Read, new string[] { "email" });
    }

~line 487

    void RequestGameRequestDialog(Dictionary<string, object> paramsDictionary)

    { 
        if (paramsDictionary != null && paramsDictionary.ContainsKey("message"))
        {
            string Message = paramsDictionary["message"] as string;
            GameRequestContent request = new GameRequestContent();
            request.Message = Message;

            if (paramsDictionary.ContainsKey("title"))
            {
                request.Title = $"{paramsDictionary["title"]}";
            }

            GameRequestDialog dialog = new Facebook.ShareKit.GameRequestDialog();
            var window = UIApplication.SharedApplication.KeyWindow;
            dialog.Content = request;
            dialog.Show();
        }

    }

Called by

await CrossFacebookClient.Current.GameRequestDialog("A message", "a Title");

Similar attempt for android.

unsure about the bolded line, I'm unsure if the sharecallback will work. The Dialog is a Xamarin.Facebook.Share.Widget so maybe it will.
