Usage

The following code connects to Ably's realtime messaging service, subscribes to a channel to receive messages, and publishes a test message to that same channel:

  // Initialize Ably Realtime client
  final clientOptions = ably.ClientOptions(
    key: 'your-ably-api-key',
    clientId: 'me',
  );
  
  final realtimeClient = ably.Realtime(options: clientOptions);
  
  // Wait for connection to be established
  await realtimeClient.connection
      .on(ably.ConnectionEvent.connected)
      .first
      .then((stateChange) {
    print('Connected to Ably');
  });
  
  // Get a reference to the 'test-channel' channel
  final channel = realtimeClient.channels.get('test-channel');
  
  // Subscribe to all messages published to this channel
  channel.subscribe().listen((ably.Message message) {
    print('Received message: ${message.data}');
  });
  
  // Publish a test message to the channel
  await channel.publish(
    name: 'test-event',
    data: 'hello world',
  );
