laravel echo

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:

✅ socket.io
✅ Pusher
✅ Null

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'));

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'
}
}
});
