isValidMixin property
bool
get
isValidMixin
Whether the class can validly be used as a mixin when defining another class.
For classes defined by a class declaration or a mixin application, the behavior of this method is defined by the Dart Language Specification in section 9:
It is a compile-time error if a declared or derived mixin refers to super. It is a compile-time error if a declared or derived mixin explicitly declares a constructor. It is a compile-time error if a mixin is derived from a class whose superclass is not Object.
Implementation
bool get isValidMixin;
