[Flutter] Flutter TCP Socket with Python send any different string

I'm trying send data to python on flutter. But I am only send "data", ı want send different "string" but this code not working. I want to send "psk" and "ssid" string. Can you help me?

import 'package:flutter/material.dart';
import 'package:tcp_socket_connection/tcp_socket_connection.dart';

class UsersPage extends StatefulWidget {
@override
_UsersPageState createState() => _UsersPageState();
}

class _UsersPageState extends State<UsersPage> {
TextEditingController nameController = TextEditingController();
TcpSocketConnection socketConnection =
TcpSocketConnection("my_ip", 9000);
String message = "";
String ssid = "";
String psk = "";

@override
void initState() {
super.initState();
startConnection();
}

//receiving and sending back a custom message
void messageReceived(String msg) {
setState(() {
message = msg;
});
}

//starting the connection and listening to the socket asynchronously
void startConnection() async {
socketConnection.enableConsolePrint(
true); //use this to see in the console what's happening
if (await socketConnection.canConnect(20000000, attempts: 1)) {
//check if it's possible to connect to the endpoint
await socketConnection.connect(2000000, messageReceived, attempts: 1);
}
}

@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
home: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[

},
child: Text('PSK'),
),
])));
}
}


import socket


s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(("0.0.0.0", 9000))
s.listen(5)

while True:
# now our endpoint knows about the OTHER endpoint.
clientsocket, address = s.accept()
print(f"Connection from {address} has been established.")
data = clientsocket.recv(1024)
psk = str(clientsocket.recv(1024))
ssid = str(clientsocket.recv(1024).decode())
print(ssid)
print(psk)
print(data)
