Element class abstract
The base class for all elements in the Dart language.
Elements represent the building blocks of a Dart program, such as classes, methods, fields, and variables. They provide a way to access information about the structure and semantics of the code.
This class provides a common interface for accessing properties like the element's name, enclosing element, library, and metadata. It also defines methods for checking the presence of specific annotations.
