Bonsoir is a Zeroconf library that allows you to discover network services and to broadcast your own. It's based on Android NSD and on Apple's popular framework Bonjour. In fact, Bonsoir can be translated into Good evening (and Bonjour into Good morning or Good afternoon depending on the current moment of the day).

Code snippet

Here is how you can broadcast your service using Bonsoir :

// Let's create our service !
BonsoirService service = BonsoirService(
  name: 'My wonderful service', // Put your service name here.
  type: '_wonderful-service._tcp', // Put your service type here. Syntax : _ServiceType._TransportProtocolName. (see http://wiki.ros.org/zeroconf/Tutorials/Understanding%20Zeroconf%20Service%20Types).
  port: 3030, // Put your service port here.
);

// And now we can broadcast it :
BonsoirBroadcast broadcast = BonsoirBroadcast(service: service);
await broadcast.ready;
await broadcast.start();

// ...

// Then if you want to stop the broadcast :
await broadcast.stop();

And here is how you can search for a broadcasted service :

// This is the type of service we're looking for :
String type = '_wonderful-service._tcp';

// Once defined, we can start the discovery :
BonsoirDiscovery discovery = BonsoirDiscovery(type: type);
await discovery.ready;

// If you want to listen to the discovery :
discovery.eventStream!.listen((event) { // `eventStream` is not null as the discovery instance is "ready" !
  if (event.type == BonsoirDiscoveryEventType.discoveryServiceFound) {
    print('Service found : ${event.service.toJson()}')
    event.service!.resolve(discovery.serviceResolver); // Should be called when the user wants to connect to this service.
  } else if (event.type == BonsoirDiscoveryEventType.discoveryServiceResolved) {
    print('Service resolved : ${event.service.toJson()}')
  } else if (event.type == BonsoirDiscoveryEventType.discoveryServiceLost) {
    print('Service lost : ${event.service.toJson()}')
  }
});

// Start the discovery **after** listening to discovery events :
await discovery.start();

// Then if you want to stop the discovery :
await discovery.stop();
