does not work for web

It's throws exception on web, but works on macos and ios:
I did not manage to get much info. Here is all I manage to gather.

`TypeError: Cannot read properties of null (reading 'inMilliseconds')

at WebSocket. (http://localhost:64578/dart_sdk.js:115590:21)`

it seams exception comes from **BaseWebSocket** class **connect** method, at line:
`...
_t = Timer?.periodic(ping, (t) {
socket.send('');
});
...
`
