Needs to be migrated for web support

[awvreenen95]

I am attempting to compile a webassembly build for a project I'm working on that makes use of mqtt. The mqtt_client library is dependent on universal_html which does not support webassembly since the dart:html library is not supported.

Please see some more details in an issue I raised on flutter repo and also an issue raised on the mqtt_client repo.

Here we're having this error when building for flutter 3.19:
Error: The type 'JSObject' can't be used as supertype.

We should really deprecate this library in favor of package:web that is vendored by the Dart team itself.

In an ideal world, yes, but package:web isn't universal either. Maybe a package:universal_web?

@schultek released a universal_web package.

Maybe @dint-dev could be invited to help maintain it if they're willing.
