Description:

wivoce laravel echo client

echo wivoce-laravel-echo-client Echo for Flutter Fork #
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.
Need to introduce pusher_client/socket_io_client plugin separately. Use the corresponding version.
Available connectors:

Pusher
socket.io


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
wivoce_laravel_echo_client: ^0.0.1
copied to clipboard
import echo and pusher_client
import 'package:wivoce_laravel_echo_client/wivoce_laravel_echo_client.dart';
import 'package:pusher_client/pusher_client.dart';
copied to clipboard
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
wivoce_laravel_echo_client: ^0.0.1
copied to clipboard
import socket_io_client
import 'package:wivoce_laravel_echo_client/wivoce_laravel_echo_client.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'));
