One common use case is Stream#listen's onError callback with StackTrace:

  stream.listen(
      (event) => ...,
      onError: (dynamic e, StackTrace stackTrace) => ...
//                         ^^^^^^^^^^
//                         avoid_types_on_closure_parameters

+1, along with #58183 I think this would make it match omit_local_variable_types, which seems desirable.

We just add a check that the (approximate) context type is a function type.
