Do you have experience implementing or working with the WebSocket protocol in projects?

Yes, I have experience working with the WebSocket protocol in Flutter projects. WebSocket allows establishing a persistent two-way connection between the client and the server, which is useful for real-time applications such as chats or notification systems.

In Flutter, I used the web_socket_channel package for working with WebSocket, which simplifies connection and message exchange.

Example of connecting and listening to messages:

import 'package:web_socket_channel/web_socket_channel.dart';

final channel = WebSocketChannel.connect(
  Uri.parse('wss://example.com/socket'),
);

channel.stream.listen((message) {
  print('Received message: $message');
});

// Sending a message
channel.sink.add('Hello, server!');

// Closing the connection
channel.sink.close();

This approach allows for efficient implementation of real-time data update functionalities.
