directly calling the iOS sdk?

It's it possible to call directly into the iOS native SDK without writing objective C bridging code?

I maintain the sounds package and would like to remove all of the objective C code and replace it with pure dart
.

Is this feasible or will I still need to build a bridging layer to call into the iOS SDK?

The SDK API I'm using also uses call backs, are callbacks support by dart native?
