Server (Node.js)

Implemented in Node.js with the 'express,socket.io' library, the server listens for Socket.io connections on port 5999 and efficiently manages incoming client messages.

Installation and Usage

1. Ensure Node.js is installed on your machine.
2. Navigate to the server directory: 'cd server'
3. Install dependencies: 'npm install'
4. Start the server: 'node index.js'
5. The server initiates on 'http://localhost:5999' to accept Socket.io connections.

Client (Flutter)

The Flutter client app connects seamlessly to the Socket.io server, enabling real-time message exchange. It leverages the 'socket_io_client' package for WebSocket communication.

Installation and Usage

1. Confirm Flutter is installed on your machine.
2. Navigate to the Flutter app directory: 'cd app'
3. Install dependencies: 'flutter pub get'
4. Connect your device or launch an emulator.
5. Run the Flutter app: 'flutter run'
6. Input the Socket.io server URL (e.g., 'http://localhost:5999')
7. Once connected, utilize the input field to dispatch messages to the server and receive real-time responses.

Functionality

• Message transmission to the server triggers upon pressing the "Send" button.
• Upon successful connection establishment, the server dispatches a welcoming "Hello, client!" message.
• Incoming messages from the server are promptly displayed within the app.
• The app incorporates predefined commands for seamless interaction with the server.
• Pressing the back button seamlessly disconnects the app from the server.
