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:

• Laravel Echo Server (SocketIO)

Getting started

Laravel Echo Server 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: ^1.0.2

import socket_io_client

import 'package:codebase_echo/codebase_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);
});


// Whispering to a channel
echo.private('private-channel').whisper('typing', {
  'user': 1
});

// Listening to a whisper
echo.private('private-channel').listenForWhisper('typing', (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'));
