name

The name of the class.

supertype

The superclass of this class.

:::dart
class Crustacean {}
class Crab is Crustacean {}

IO.print(Crab.supertype)        // "Crustacean"

A class with no explicit superclass implicitly inherits Object:

:::dart
IO.print(Crustacean.supertype)  // "Object"

Object forms the root of the class hierarchy and has no supertype:

:::dart
IO.print(Object.supertype)  // "null"
