serverToServer static method

Future<SocketConnector> serverToServer({ InternetAddress? serverAddressA, InternetAddress? serverAddressB, int? serverPortA, int? serverPortB, bool? verbose, })

Binds two Server sockets on specified Internet Addresses. Ports on which to listen can be given but if not given a spare port will be found by the OS. Finally relays data between sockets and optionaly displays contents using the verbose flag

Implementation

static Future<SocketConnector> serverToServer(
    {InternetAddress? serverAddressA,
    InternetAddress? serverAddressB,
    int? serverPortA,
    int? serverPortB,
    bool? verbose}) async {
  InternetAddress senderBindAddress;
  InternetAddress receiverBindAddress;
  serverPortA ??= 0;
  serverPortB ??= 0;
  verbose ??= false;
  serverAddressA ??= InternetAddress.anyIPv4;
  serverAddressB ??= InternetAddress.anyIPv4;

  senderBindAddress = serverAddressA;
  receiverBindAddress = serverAddressA;

  //List<SocketStream> socketStreams;
  SocketConnector socketStream = SocketConnector(null, null, 0, 0, null, null);
  // bind the socket server to an address and port
  socketStream._serverSocketA = await ServerSocket.bind(senderBindAddress, serverPortA);
  // bind the socket server to an address and port
  socketStream._serverSocketB = await ServerSocket.bind(receiverBindAddress, serverPortB);

  // listen for sender connections to the server
  socketStream._serverSocketA?.listen((
    sender,
  ) {
    _handleSingleConnection(sender, true, socketStream, verbose!);
  });

  // listen for receiver connections to the server
  socketStream._serverSocketB?.listen((receiver) {
    _handleSingleConnection(receiver, false, socketStream, verbose!);
  });

  return (socketStream);
