Hello. I put the server example in the code and it is giving an error. Could you please help me?

Code:

import React, { useEffect, useRef } from "react";

import { View, Text, ImageBackground } from "react-native";
import Button from "../../components/button";
import splashImg from "../../assets/splash.png";
import { useDispatch, useSelector } from "react-redux";
import { getUserInfo } from "../../store/Identity/Authenticate/selectors";
import { fetchUser } from "../../store/Identity/Authenticate/thunks";
import { AppRoutes } from "../../navigation/routes";
import TcpSocket from "react-native-tcp-socket";

const LoginPage = ({ navigation }) => {
  const server = TcpSocket.createServer(function (socket) {
    socket.on("data", (data) => {
      socket.write("Echo server " + data);
    });

    socket.on("error", (error) => {
      console.log("An error ocurred with client socket ", error);
    });

    socket.on("close", (error) => {
      console.log("Closed connection with ", socket.address());
    });
  }).listen({ port: 12345, host: "0.0.0.0" });

  server.on("error", (error) => {
    console.log("An error ocurred with the server", error);
  });

  server.on("close", () => {
    console.log("Server closed connection");
  });
  return (
    <View style={{ flex: 1 }}>
      <ImageBackground
        style={{
          flex: 1,
          justifyContent: "flex-end",
          alignItems: "center",
        }}
        source={splashImg}
        resizeMode="cover"
      >
        <View style={{ width: "50%", marginBottom: 100 }}>
          <Button
            title="Entrar"
            onPress={() => navigation.navigate(AppRoutes.filterPage)}
            type="secondary"
          />
        </View>
      </ImageBackground>
    </View>
  );
};

export default LoginPage;
