Port of official Laravel Echo package for your Flutter apps.

Laravel Echo for Flutter #

Basically, this package is port of official Laravel Echo javascript library. It helps subscribe to channels and listen for events broadcasted from your Laravel app.

API is mostly same as official Echo package, so everything in Official documentation should work.

Available connectors:

Getting started #

Pusher #

To use with Pusher, you need to install pusher_client for you Flutter app.

In your pubspec.yaml file:

dependencies:
  ...
  pusher_client: ^2.0.0
  laravel_echo: ^1.0.0

import laravel_echo and pusher_client

import 'package:laravel_echo/laravel_echo.dart';
import 'package:pusher_client/pusher_client.dart';
const String PUSHER_KEY = 'YOUR_PUSHER_KEY_HERE';
const String PUSHER_CLUSTER = 'YOUR_PUSHER_CLUSTER_HERE';
const String BEARER_TOKEN = 'YOUR_BEARER_TOKEN_HERE';
const String AUTH_URL = 'http://echo.test/api/broadcasting/auth';

PusherOptions options = PusherOptions(
  cluster: PUSHER_CLUSTER,
  auth: PusherAuth(
    AUTH_URL,
    headers: {
      'Authorization': 'Bearer $BEARER_TOKEN',
    },
  ),
);

// Create pusher client
PusherClient pusherClient = PusherClient(
  PUSHER_KEY,
  options,
  autoConnect: false,
  enableLogging: true,
);

// Create echo instance
Echo echo = new Echo(
  broadcaster: EchoBroadcasterType.Pusher,
  client: pusherClient,
);

// Listening public channel
echo.channel('public-channel').listen('PublicEvent', (e) {
  print(e);
});

// Accessing pusher instance
echo.connector.pusher.onConnectionStateChange((state) {
  print(state!.currentState.toString());
});

socket.io #

To use with socket.io, you need to install socket_io_client for your Flutter app.

In your pubspec.yaml file:

dependencies:
  ...
  socket_io_client: ^1.0.1
  laravel_echo: ^1.0.0

import socket_io_client

import 'package:laravel_echo/laravel_echo.dart';
import 'package:socket_io_client/socket_io_client.dart' as IO;

usage

const String BEARER_TOKEN = 'YOUR_BEARER_TOKEN_HERE';

// Create socket.io client
IO.Socket socket = IO.io(
  'http://localhost:6001',
  IO.OptionBuilder()
      .disableAutoConnect()
      .setTransports(['websocket']).build(),
);

// Create echo instance
Echo echo = new Echo(
  broadcaster: EchoBroadcasterType.SocketIO,
  client: socket,
  options: {
    'auth': {
      'headers': {
        'Authorization': 'Bearer $BEARER_TOKEN',
      }
    },
  },
);

// Listening public channel
echo.channel('public-channel').listen('PublicEvent', (e) {
  print(e);
});

// Listening private channel
// Needs auth. See details how to authorize channel below in guides
echo.private('private-channel').listen('PrivateEvent', (e) {
  print(e);
});

// Listening presence channel
// Needs auth. See details how to authorize channel below in guides
echo.join('presence-channel')
  .here((users) {
    print(users);
  }).joining((user) {
    print(user);
  }).leaving((user) {
    print(user);
  }).listen('PresenceEvent', (e) {
    print(e);
  });

// Accessing socket instance
echo.connector.socket.onConnect((_) => print('connected'));
echo.connector.socket.onDisconnect((_) => print('disconnected'));
