ConstructorDeclaration class abstract

Represents a constructor of a Dart class, including its parameters, modifiers (const, factory), and the ability to create new instances.

This abstraction allows runtime instantiation of classes using metadata.

Example

class Person {
  final String name;
  final int age;

  Person(this.name, this.age);
}

final constructor = reflector.reflectConstructor(Person);
final person = constructor.newInstance({'name': 'Alice', 'age': 30});
print(person.name); // Alice

This is especially useful in frameworks like dependency injection, serialization, and code generation where runtime construction is needed.
