would be nice to have flutter web support

Additional context: I'm looking for a way to run js in my app. My app is multiplatform and runs in chrome, iOS, etc. flutter_js seems to work for mac and ios, but i get "dart:ffi" errors when trying to use it from chrome.

It would be very helpful to not have to have separate JS codepaths in my app, one for chrome and one for all the other environments.
