Description:

udp

Lightweight UDP library for Dart.
Usage #
A simple usage example:
import 'package:udp/udp.dart';

main() async {
// creates a UDP instance and binds it to the first available network
// interface on port 65000.
var sender = await UDP.bind(Endpoint.any(port: Port(65000)));

// send a simple string to a broadcast endpoint on port 65001.
var dataLength = await sender.send("Hello World!".codeUnits,
Endpoint.broadcast(port: Port(65001)));

stdout.write("$dataLength bytes sent.");

// creates a new UDP instance and binds it to the local address and the port
// 65002.
var receiver = await UDP.bind(Endpoint.loopback(port: Port(65002)));

// receiving\listening
receiver.asStream(timeout: Duration(seconds: 20)).listen((datagram) {
var str = String.fromCharCodes(datagram.data);
stdout.write(str);
});

// close the UDP instances and their sockets.
sender.close();
receiver.close();

// MULTICAST
var multicastEndpoint =
Endpoint.multicast(InternetAddress("239.1.2.3"), port: Port(54321));

var receiver = await UDP.bind(multicastEndpoint);

var sender = await UDP.bind(Endpoint.any());

receiver.asStream().listen((datagram) {
if (datagram != null) {
var str = String.fromCharCodes(datagram?.data);

stdout.write(str);
}
});

await sender.send("Foo".codeUnits, multicastEndpoint);

await Future.delayed(Duration(seconds:5));

sender.close();
receiver.close();
