protected top-level constant

const protected = const _Protected()

Used to annotate an instance member (method, getter, setter, operator, or field) m in a class C. If the annotation is on a field it applies to the getter, and setter if appropriate, that are induced by the field. Indicates that m should only be invoked from instance methods of C or classes that extend, implement or mix in C, either directly or indirectly. Additionally indicates that m should only be invoked on this, whether explicitly or implicitly.

Tools, such as the analyzer, can provide feedback if

the annotation is associated with anything other than an instance member, or an invocation of a member that has this annotation is used outside of an instance member defined on a class that extends or mixes in the class in which the protected member is defined, or that uses a receiver other than this.
