coucou_flutter 0.0.3

pub package

Coucou (Flutter) #

Coucou is a network service discovery and broadcast library for Flutter that supports both Android and iOS. The platform-specific implementations are utilizing coucou_android (v0.1.1) and coucou_ios (v0.0.6).

Note: This plugin is still in very early stage of development and there are many things that are yet to be done. For more information, take a look at the todo list down below.

Coucou API #

The API is very similar to the ones on Android and iOS.

Stream<dynamic> startDiscovery(String type, {String domain = "local."});
Future<dynamic> stopDiscovery({String type});
Future<Disposable> startBroadcast(BroadcastConfig config);
Future<dynamic> stopBroadcast({BroadcastConfig config});

Note: The API will be slightly changed in a way that it will provide streams/futures of concrete types. For more information about future works, take a look at the todo section at the end of the readme.

Creation #

final coucou = Coucou();

Network Service Discovery #

final discovery = coucou.startDiscovery("_http._tcp").listen((event) {
  // TODO: Something with the current event
}, onError: (error) {
  // TODO: Something with the error

// .. when not needed, dispose


Network Service Broadcast #

final broadcast = await coucou.startBroadcast(BroadcastConfig(
  type: "_http._tcp",
  name: "My service",
  port: 12345,

// when not needed, dispose

Note: Broadcast requests currently are not supported, but the API is there.

Requirements #

  • Min sdk for Android is API level 16.
  • Min iOS version is 8.0.


  • Support for network service broadcasts
  • Acknowledge the domain parameter on the Android side for service discovery. This has to be implemented in the coucou_android project first.
  • Provide a handier way to cancel a discovery, similar to how the iOS and Android implementations work.
  • Support for multiple broadcasts running in parallel
  • Support for multiple service discoveries running in parallel
  • Better sample app that demonstrates the usage of this library
  • Improve documentation
  • Write tests
