For real-time data updates from a Web API, Flutter can use the ______ protocol.
- HTTP/2
- TCP
- UDP
- WebSocket
For real-time data updates from a Web API, Flutter can use the WebSocket protocol. Unlike traditional HTTP requests, which are request-response-based, WebSockets provide a full-duplex communication channel between the client and the server. This allows for bi-directional communication, making it suitable for scenarios where real-time updates are crucial. Understanding the use of WebSockets in Flutter is important for implementing features like live chats, notifications, or any other real-time data synchronization in Flutter applications.
