FunctionRuntimeType class
Runtime model of a function type such as int Function(String, [double]) or
void Function({int count}). Subtyping is structural: return type
covariant, parameters contravariant, arities and named-parameter shape must
line up.

-
A function type with no declared shape — used as the default for callables
whose parameter/return annotations could not be resolved. It matches any
other function type.
