Using the Linter

Dart 2.1 introduced a new syntax for mixins that provides a safe way for a mixin to invoke inherited members using super. The new style of mixins should always be used for types that are to be mixed in. As a result, this lint will flag any uses of a class in a with clause.


class A {}
class B extends Object with A {}


mixin M {}
class C with M {}
