🚀 [firebase_remote_config] Add real time updates on web

What feature would you like to see?

Firebase now supports real time updates on Firebase Remote Config for web. We should update the flutter package to allow the same on Flutter web.

This would be amazing. Is there any way to get around this in the meantime? i.e. have real time web remote config updates?
