Why it is adding port number zero at the end of url automatically ? How can i remove the port number. I want to run it without port number.

@jumperchen can you please have a look at it? Here are the details.

client : ^2.0.0-beta.4-nullsafety.0
platform : flutter web
server : version 3.1.2

Here is the code.

import 'package:socket_io_client/socket_io_client.dart' as IO;

IO.Socket socket = IO.io(
      'wss://socket.example.com',
      IO.OptionBuilder()
          .setTransports(['websocket'])
          .build());

With the above code, the URL becomes: wss://socket.example.com:0/socket.io/?EIO=4&transport=websocket :0 after socket.example.com

I think the issue is with the file socket_io_client.dart:49. If no port is passed then due to null safety it takes default int value 0.

Solution:

For those who are looking solution for it, pass a port number while connecting. If no custom port by server, for ws pass 80 for wss pass 443. Example:

import 'package:socket_io_client/socket_io_client.dart' as IO;

IO.Socket socket = IO.io(
      'wss://socket.example.com:443',
      IO.OptionBuilder()
          .setTransports(['websocket'])
          .build());
