DartObject class Null safety

A representation of the value of a compile-time constant expression.

Note that, unlike the mirrors system, the object being represented does not exist. This interface allows static analysis tools to determine something about the state of the object that would exist if the code that creates the object were executed, but none of the code being analyzed is actually executed.

Clients may not extend, implement or mix-in this class.
