Connects to the mqtt broker. The connection must respect the last will parameters. The connect method of each instance may only be called once. If it is called a second time on the same instance a StateError must be thrown.

disconnect() → Future<Null>

Disconnects from the mqtt broker and cancels all subscriptions.

noSuchMethod(Invocation invocation) → dynamic

publish(String topic, Uint8List data, bool retained, int qos) → Future<Null>

Publishes data to topic with respect to retained. Awaiting the returned future should guarantee the publishing of the message to the broker with respect to the quality of service qos. A qos of 0 does not guarentee anything and might return immediately. If this is called while disconnecting, a DisconnectingError should be thrown

subscribe(String topic, int qos) → Future<Stream<Uint8List>>

Subscribes to topic. Awaiting the returned future gives a Stream whichs events are incoming messages on the topic. If this is called while disconnecting, a DisconnectingError should be thrown.
