AmarWave Flutter / Dart SDK

Official Dart/Flutter client SDK for AmarWave — the real-time WebSocket platform.

Installation

Add to your pubspec.yaml:

dependencies:
  amarwave:
    path: ../sdk/flutter   # local path during development
    # OR from pub.dev once published:
    # amarwave: ^1.0.0

Quick Start

import 'package:amarwave/amarwave.dart';

void main() {
  final aw = AmarWave(
    const AmarWaveConfig(
      appKey: 'YOUR_APP_KEY',
      cluster: 'default',   // resolves amarwave.com automatically
    ),
  );

  aw.connection.bind('connected', (_) {
    print('Connected! Socket ID: ${aw.connection.socketId}');
  });

  final ch = aw.subscribe('public-chat');

  ch.bind('message', (data) {
    print('New message: $data');
  });

  aw.connect();
}

Configuration

Parameter	Type	Default	Description
appKey	String	required	Your AmarWave application key
cluster	String?	null	Named cluster — auto-resolves host/port ('default', 'eu', 'us', 'ap1', 'ap2')
appSecret	String?	null	App secret for client-side HMAC auth
wssPort	int	cluster value	WebSocket TLS port override
apiHost	String?	cluster value	HTTP API hostname override
apiPort	int	cluster value	HTTP API port override
forceTLS	bool	false	Force wss:// and https://
authEndpoint	String	'/broadcasting/auth'	Server-side auth endpoint
authHeaders	Map<String,String>	{}	Extra auth request headers
reconnectDelay	Duration	1s	Base reconnect delay
maxReconnectDelay	Duration	30s	Max reconnect delay
maxRetries	int	5	Max retries (0 = infinite)
activityTimeout	Duration	120s	Ping inactivity timeout
pongTimeout	Duration	30s	Pong wait timeout
disableStats	bool	false	Disable usage stats in pings

Channel Types

Public Channel

No authentication required.

final ch = aw.subscribe('public-chat');
ch.bind('message', (data) => print(data));

Private Channel

Requires HMAC auth. Either set appSecret in config (client-side, not for production) or configure an authEndpoint on your backend.

final ch = aw.subscribe('private-orders');
ch.bind('order-placed', (data) => print(data));

Presence Channel

Like private channels, but also tracks which members are subscribed.

final lobby = aw.subscribe('presence-lobby') as AmarWavePresenceChannel;

lobby.bind('subscribed', (_) {
  print('Members: ${lobby.memberCount}');
  print('All members: ${lobby.members}');
});

lobby.bind('amarwave_internal:member_added', (data) {
  print('Joined: $data');
});

lobby.bind('amarwave_internal:member_removed', (data) {
  print('Left: $data');
});

Publishing Events

Events can be published via the HTTP API. This works from both client and server.

Via channel reference

final ch = aw.subscribe('public-chat');
await ch.publish('message', {'user': 'Alice', 'text': 'Hello!'});

Via top-level shortcut

await aw.publish('public-chat', 'message', {'user': 'Alice', 'text': 'Hello!'});

Publishing is queued automatically before subscription confirmation and flushed once the server confirms the subscription.

Connection Lifecycle Events

Bind on aw.connection or directly on aw:

aw.connection.bind('connected', (_) => print('Connected'));
aw.connection.bind('disconnected', (_) => print('Disconnected'));
aw.connection.bind('connecting', (_) => print('Connecting...'));
aw.connection.bind('failed', (_) => print('Max retries exceeded'));
aw.bind('error', (err) => print('Error: $err'));

Disconnect

aw.disconnect();

This stops all reconnect attempts and closes the WebSocket cleanly.

Unsubscribe

aw.unsubscribe('public-chat');

Global Event Listener

Listen to every event on a channel:

ch.bindGlobal((event, data) => print('Event: $event, Data: $data'));

Server-Side Auth Endpoint

For private/presence channels in production, implement an auth endpoint on your backend:

POST /broadcasting/auth
Body: { "socket_id": "...", "channel_name": "private-orders" }
Response: { "auth": "<appKey>:<hmac_signature>" }

The PHP SDK ships with authenticate() and authenticatePresence() helpers for this.
