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

Three connectors available:

Getting started

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: ^0.9.1
  laravel_echo:

import socket_io_client

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

usage

// Create echo instance
Echo echo = new Echo({
  'broadcaster': 'socket.io',
  'client': IO.io,
});

// 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.socket.on('connect', (_) => print('connected'));
echo.socket.on('disconnect', (_) => print('disconnected'));

Pusher (NOT TESTED)

DONT USE THIS FOR NOW will look at Pusher in following weeks. Any contributions welcomed.

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

In your pubspec.yaml file:

dependencies:
  ...
  pusher: ^1.0.0
  laravel_echo:
Pusher pusher = new Pusher('PUSHER_APP_ID', 'PUSHER_APP_KEY', 'PUSHER_APP_SECRET');

Echo echo = new Echo({
  'broadcaster': 'pusher',
  'client': pusher,
});

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

socket.on('connect', (_) => print('connect'));
socket.on('disconnect', (_) => print('disconnect'));

Authorize private channels

To authorize channel requests we use Laravel Passport

In our BroadcastServiceProvider.php we need to enable

Broadcast::routes(['middleware' => ['auth:api']]);

then, when creating Echo instance include Authorization header with bearer token

echo = new Echo({
  'broadcaster': 'socket.io',
  'client': socket,
  'auth': {
    'headers': {
        'Authorization': 'Bearer $token'
    }
  }
});
