Usage

dependencies:

import 'package:messaging_signalr/messaging_signalr.dart';

Initializing

In the first step you must call init function before use package features. In init function you have to configure server address and pass the the fireBase token you have received from FirebaseMessaging (see firebase_messaging package) then you have to pass some call back function to it which will be called when a task fails or succeeds.

  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 */
  );

Usage

                height: 65,
                decoration: const BoxDecoration(
