ConstructorElementImpl class

Implementation of a constructor element in a Dart class.

This class represents constructors that create instances of classes. It provides implementations for constructor-specific functionality such as handling redirecting constructors, superclass constructor calls, and different constructor types (const, factory, etc.).
