Add Flutter Web support

[tolstenko]

Hey fellow unicamper! I would love to see this working on web too! Tks

Yah, That my friends is almost impossible right now. Unless we manage to connect wasm to a flutter web app and manage to compile our C sources to wasm.

This could help somehow.
https://api.dartlang.org/stable/2.6.1/dart-html/AudioElement-class.html
https://api.dartlang.org/stable/2.6.1/dart-html/MediaElement-class.html
Or maybe using document and dom we could write the same functionality.

Right, and then how come we would bridge the FFI to call js methods?

PS: I'm avoiding PlatformChannelsdue to the possibility od FFI packages become something different than plugins.

Any update?
