RawSocketEvent class

Events for the RawDatagramSocket, RawSecureSocket, and RawSocket.

These event objects are used by the Stream behavior of the sockets (for example RawSocket.listen, RawSocket.forEach) when the socket's state change.

import 'dart:convert';
import 'dart:io';

void main() async {
  final socket = await RawSocket.connect("example.com", 80);

  socket.listen((event) {
    switch (event) {
      case RawSocketEvent.read:
        final data = socket.read();
        if (data != null) {
          print(ascii.decode(data));
        }
        break;
      case RawSocketEvent.write:
        socket.write(ascii.encode('GET /\r\nHost: example.com\r\n\r\n'));
        socket.writeEventsEnabled = false;
        break;
      case RawSocketEvent.readClosed:
        socket.close();
        break;
      case RawSocketEvent.closed:
        break;
      default:
        throw "Unexpected event $event";
    }
  });
}
