Socket Support on Web broken

[RiRa12621]

I am fairly new to flutter and trying to implement a simple ssh-client in a terminal view. However when I test it on web, I get errors along the lines of

Error: UnimplementedError: Native socket is not supported on web

So, I am not handling the error, but the actual error could maybe be fixed following the comments in the bug report to flutter/flutter: flutter/flutter#45982 (comment) which should, to my understanding, be implemented in the following line:

dartssh2/lib/src/socket/ssh_socket_io.dart

Line 12 in 679b841

final socket = await Socket.connect(host, port, timeout: timeout);

my code for the ssh connections looks as follows:

    final client = SSHClient(
      await SSHSocket.connect(host, port),
      username: username,
      onPasswordRequest: () => password,
    );

Same here, problem it still exists on web 👎🏻

Does anyone know, is the problem exists on earlier versions?

  final socket = await SSHSocket.connect('localhost', 22);

  final client = SSHClient(
    socket,
    username: 'root',
    onPasswordRequest: () => '1234567',
  );

Hello,

Sorry for the delay in my response. It's actually intended that SSHSocket don't provide a default implementation on web platform as there is no standard method for connecting to sockets in browsers. Instead you can implement the SSHSocket interface use whatever available in the browser such as bare WebSocket, socket.io, WebRTC data channels or WebExtension native messaging.

Please let me know if you have any further questions or concerns.

Fine to close, if it's intended behaviour
