Usage

//Add this import for every dart file using Mobile Chat Flutter functions
import 'package:mobile_chat_flutter/mobile_chat_flutter.dart';

Initialization

Implement this initialization function as early as possible in your app

MobileChatInitialization.init(
    appId: string, 
    clientId: string, 
    secretKey: string, 
    externalId: string, 
    fullName: string
) : string

Parameter appId, clientId, secretKey can be found in integration page. ParameterexternalId is your customer unique identifier and fullName is your customer full name.

Example initialization with customer unique id and customer full name in your UserInfo class when login successful.

//Your function to handle login successful
onLoginSuccessful(UserInfo userInfo) {
  //...  
  MobileChatInitialization.init(
    "YOUR_APP_ID",
    "YOUR_CLIENT_ID",
    "YOUR_SECRET_KEY",
    "${userInfo.id}",
    "${userInfo.fullName}",
  );
  //... 
}

Conversation feature

MobileChatScreen used by your customer to make conversation with your agents.

@override
Widget build(BuildContext context) {
  return MaterialApp(
        title: 'Your app title',
        onGenerateRoute: (settings) {
          final argument = settings.arguments;
          switch (settings.name) {
            case 'route-key-to-mobile-chat-screen':
              return MaterialPageRoute(
                builder: (_) => const MobileChatScreen(),
              );
          }
        }
  );
}

//Implement this to navigate to mobile chat screen
navigator.pushNamed(context, 'route-key-to-mobile-chat-screen');

Notification feature

Register your customer fcm token to mobile chat server to get notification from agent

registerMobileChatNotification(fcmToken: string) : string

To distinct mobile chat payload and your own payload, use this function

isMobileChatPayload() : boolean

To get state of mobile chat component is opened or not

isMobileChatOpened() : boolean

To stop getting notification, implement function below. This can be used when your customer logout from your app.

revokeNotification() : string

Example implementation of notification feature

//Register your FCM token to Mobile Chat
FirebaseMessaging.instance.getToken().then((fcmToken) async {
    await MobileChatNotification.registerNotification(fcmToken ?? "");
});

//Handle receive notification from Mobile Chat
FirebaseMessaging.onMessage.listen((RemoteMessage remoteMessage) {
    if (MobileChatNotification.isMobileChatPayload(remoteMessage.toMap())) {
      if (!MobileChatNotification.isMobileChatOpened()) {
        //Handle Mobile Chat notification here

      }
    }else{
      //Handle your own notification here
    }
});
