does not connect to a minimal socket io node js server

[boussarilatif]

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

main() {

IO.Socket socket = IO.io('http://localhost:8000');
socket.on('connect', (_) {
 print('connect');
 socket.emit('msg', 'test');
});
socket.on('event', (data) => print(data));
socket.on('disconnect', (_) => print('disconnect'));
socket.on('fromServer', (_) => print(_));

}

//node js server
const io = require("socket.io"),
server = io.listen(8000);

let sequenceNumberByClient = new Map();

server.on("connection", socket => {
console.info(Client connected [id=${socket.id}]);

sequenceNumberByClient.set(socket, 1);

socket.on("disconnect", () => {
sequenceNumberByClient.delete(socket);
console.info(Client gone [id=${socket.id}]);
});
});

maybe you need add trasport option when creating socket instance

socket = IO.io('http://localhost:8000', <String, dynamic>{
        'transports': ['websocket'],
      });

worked for me
