  SignalRMessaging.init(
      serverAddress: 'http://167.235.239.170:5025/Myhub',
      firebaseToken: ConstValues.fireBaseToken,
      onSendMessage: (){},// will be called when sending message to contact or group has done
      onGetContactInfo: (){},/* when you invoke addNewContact method after After receiving contact info completed this method will
      be called  */
      onGetContactInfoCanceled: (String message){},//if getting contact info faces problem and fails this
      method will be called the string shows the reason of failure
      onCreateGroup: (String message){}/* after invoking createGroup if task completed successfully
      this function will be called the message show that you create this group or the group exists previously
      and you join it string show the result of action */
  );
