package:shelf_web_socket v3.0.0

• BREAKING:: Change the signature of the webSocketHandler method's
  onConnection callback. Previously this took an untyped function with either
  one or two parameters. This now requires a ConnectionCallback; a typedef
  taking two parameters. See also #457.
• Add a API usage example.
• Require Dart ^3.5.0.

Note that most clients seeing analysis issues from the above breaking change can
fix it by adding a second parameter to their callback. So, they would change
this:

webSocketHandler((webSocket) {
  webSocket.stream.listen((message) {
    webSocket.sink.add('echo $message');
  });
});

to this:

webSocketHandler((webSocket, _) {
  webSocket.stream.listen((message) {
    webSocket.sink.add('echo $message');
  });
});
