dart:html WebSocket vs dart:io WebSocket

I was looking out for a sample WebSocket implementation on DartPad.

Here's a link to the implementation: WebSocket Sample

However, while trying to implement the same on my local machine, I encountered that Dart has two implementations of the WebSocket class.

One is provided in the dart:io package and another is provided in dart:html package.

Can anyone provide what's the difference between the two and what are the advantages of one over the other?

There is no major difference other than some implementation changes in both libraries:

WS in dart:io: https://api.dart.dev/stable/2.7.0/dart-io/WebSocket-class.html

WS in dart:html: https://api.dart.dev/stable/2.7.0/dart-html/WebSocket-class.html#constructors

if you see closely both the classes have the same approach in everything except creating a web socket instance.

dart:io :

Simple no arg constructor is deprecated. But has a factory method to create an instance using a Socket.

dart:html :

Websocket constructor takes a url string and a list of protocol objects.

The one in dart:io is used for standalone app running on Dart VM including Flutter, while the one in dart:html is for Web browsers.
