        /// </summary>

        public class FirebaseClassData

        {

            /// <summary>

            /// KeyName

            /// </summary>

            public string KeyName { get; set; }

            /// <summary>

            /// KeyValues

            /// </summary>

            public List<Dictionary<string,string>> KeyValues { get; set; }

        }

Hi @Anonymous

got the solution for Android and iOS is pending .

below solution for android regarding how to pass items to firebase.

/// <summary>
        /// LogEvent

        /// <param name="eventId"></param>
        /// <param name="parameters"></param>
        /// <param name="items"></param>
        public void LogEvent(string eventId, IDictionary<string, string> parameters, List<Constants.FirebaseClassData> items)
