Lightweight UDP library for Dart.

## Usage

A simple usage example:

```dart

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();

  

}

```
