courier_protobuf

Courier Protobuf MessageAdater for Courier Dart SDK

Getting Started

Run this command:

With Flutter:

$ flutter pub add courier_protobuf

This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):

dependencies:
  courier_protobuf: 0.0.2

You can use this package along with courier_dart_sdk if you want to use Protobuf as MesageAdapter for your CourierClient.

final CourierClient courierClient = CourierClient.create(
    ...
      messageAdapters: const <MessageAdapter>[
          ProtobufMessageAdapter(),
          ...
      ])
  );

Decode bytes to Pet.pb GeneratedMessage:

courierClient
        .courierMessageStream<Pet>(
            "pet/6b57d4e5-0fce-4917-b343-c8a1c77405e5/update",
            decoder: Pet.fromBuffer)
        .listen((pet) {
      print("Message received Pet: ${pet.name}");
    });

Encode Pet GeneratedMessage pb to bytes:

final pet = Pet();
    pet.name = "Hello Pet";
    courierClient.publishCourierMessage(CourierMessage(
        payload: pet,
        topic: "pet/6b57d4e5-0fce-4917-b343-c8a1c77405e5/update",
        qos: QoS.one));
