Publish Message

To publish message to the broker, you need can pass your object instance, it will try to loop all message adapters to encode the instance into Uint8List, the first one that is able to encode, will be used. You can also pass an optional, encoder function that will pass your instance as dynamic which you can use to call your own method to encode to Uint8List

You need to initalize CourierMessage instance passing the payload, topic string, and qos like so. Finally, you need to invoke publishCourierMessage on CourierClient passing the message.

Optionally you can pass MessageAdapter If this is passed, it will use it encode the data to Uint8List, otherwise it will use the messageAdapters list passed when initializing CourierClient.

/// This used JSONMessageAdapter which use dart jsonEncode to invoke toJson on object implicitly
courierClient.publishCourierMessage(CourierMessage(
    payload: Person(name: textMessage),
    topic: "person/6b57d4e5-0fce-4917-b343-c8a1c77405e5/update",
    qos: QoS.one));

/// For this TestData without toJson method, you can provide your own encode to convert to Uint8List/bytes
courierClient.publishCourierMessage(
    CourierMessage(
        payload: testData,
        topic: "orders/6b57d4e5-0fce-4917-b343-c8a1c77405e5/update",
        qos: QoS.one),
    encoder: (testData) => testData.toBytes());
