Node.js Socket IOFlutter 未连接

我在将socket io Flatter客户端连接到nodejs socket io服务器时遇到问题.

即.，

socket_io_client: ^1.0.2

服务器端.

{
   "socket.io": "^2.4.1",
}

我也try 了最新的依赖项，但我在日志(log)中收到了同样的timeout条消息，

下面我将添加服务器端和客户端的实现，

const { socketGuard } = require('./middlewares/socketio.middleware');
let io;

module.exports = {

    init: (server) => {
        
        io = require("socket.io")(server, { cors: { origin: '*' } });

        io.use(async (socket, next) => {

            let result = await socketGuard(socket);

            if (result.isValid) {
                next();
            }
            else {
                next(new Error("Not authorized"));
            }

        });

        io.on("connection", (socket) => {

            console.log(`${socket.id} : connected`);

        });

        return io;
    },

    get: () => {


        if (!io) {


            throw new Error("Socket io not initialized");

        }

        return io;

    }

};

对于Flutter ，我在init函数中添加了以下几行:，

    io.Socket socket = io.io("http://192.168.1.14:5000");

    socket.onConnect((data) {log("Hello world");});

    socket.onConnectError((data) {log(data);});

    socket.onError((data) {log(data);});

    socket.on("message", (data) {log(data);});
