Properties

accessors → List<PropertyAccessorElement>
Return a list containing all of the accessors (getters and setters) declared in this class.
no setterinherited
allSupertypes → List<InterfaceType>
Return a list containing all the supertypes defined for this element and its supertypes. This includes superclasses, mixins, interfaces, and superclass constraints.
no setter
children → List<Element>
A list of this element's children. There is no guarantee of the order in which the children will be included.
no setterinherited
constructors → List<ConstructorElement>
Return a list containing all of the constructors declared in this class. The list will be empty if there are no constructors defined for this class, as is the case when this element represents an enum or a mixin.
no setterinherited
context → AnalysisContext
Return the analysis context in which this element is defined.
no setterinherited
declaration → Element
Return the declaration of this element. If the element is a view on an element, e.g. a method from an interface type, with substituted type parameters, return the corresponding element from the class, without any substitutions. If this element is already a declaration (or a synthetic element, e.g. a synthetic property accessor), return itself.
no setterinherited
displayName → String
Return the display name of this element, possibly the empty string if this element does not have a name.
no setterinherited
documentationComment → String?
Return the content of the documentation comment (including delimiters) for this element, or null if this element does not or cannot have documentation.
no setterinherited
enclosingElement → CompilationUnitElement
Return the element that either physically or logically encloses this element. This will be null if this element is a library because libraries are the top-level elements in the model.
