Type class Null safety

Runtime representation of a type.

Type objects represent types. A type object can be created in several ways:

  • By a type literal, a type name occurring as an expression, like Type type = int;, or a type variable occurring as an expression, like Type type = T;.
  • By reading the run-time type of an object, like Type type = o.runtimeType;.
  • Through dart:mirrors.

A type object is intended as an entry point for using dart:mirrors. The only operations supported are comparing to other type objects for equality, and converting it to a string for debugging.




hashCode int
A hash code for the type which is compatible with operator==.
read-only, override
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited


noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
toString() String
Returns a string which represents the underlying type.


operator ==(Object other) bool
Whether other is a Type instance representing an equivalent type.
