ConstructorElement()

Properties

augmentation → ConstructorAugmentationElement?
The immediate augmentation of this element, or null if there are no augmentations. ConstructorAugmentationElement.augmentationTarget is the back pointer that will point at this element.
read-only
children → List<Element>
A list of this element's children. There is no guarantee of the order in which the children will be included.
read-onlyinherited
context → AnalysisContext
Return the analysis context in which this element is defined.
read-onlyinherited
declaration → ConstructorElement
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.
read-onlyoverride
displayName → String
Return the display name of this element, possibly the empty string if this element does not have a name.
read-onlyoverride
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.
read-onlyinherited
enclosingElement → InterfaceElement
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.
read-onlyoverride
enclosingElement3 → InterfaceElement
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.

The unique integer identifier of this element.
read-onlyinherited

Return true if this executable element has body marked as being asynchronous.
read-onlyinherited
isConst → bool
Return true if this constructor is a const constructor.
read-only
isConstantEvaluated → bool
Return whether this constant is evaluated.
read-onlyinherited
isDefaultConstructor → bool
Return true if this constructor can be used as a default constructor - unnamed and has no required parameters.
read-only
isExternal → bool
Return true if this executable element is external. Executable elements are external if they are explicitly marked as such using the 'external' keyword.
read-onlyinherited

Return true if this constructor represents a generative constructor.
read-only

isOperator → bool
Return true if this executable element is an operator. The test may be based on the name of the executable element, in which case the result will be correct when the name is legal.
read-onlyinherited
isPrivate → bool
Return true if this element is private. Private elements are visible only within the library in which they are declared.
read-onlyinherited
isPublic → bool
Return true if this element is public. Public elements are visible within any library that imports the library in which they are declared.
read-onlyinherited
isSimplyBounded → bool
If the element defines a type, indicates whether the type may safely appear without explicit type parameters as the bounds of a type parameter declaration.
read-onlyinherited
isStatic → bool
Return true if this element is a static element. A static element is an element that is not associated with a particular instance, but rather with an entire library or class.
read-onlyinherited
isSynchronous → bool
Return true if this executable element has a body marked as being synchronous.
read-onlyinherited
isSynthetic → bool
Return true if this element is synthetic. A synthetic element is an element that is not represented in the source code explicitly, but is implied by the source code, such as the default constructor for a class that does not explicitly define any constructors.
read-onlyinherited
kind → ElementKind
Return the kind of element that this is.
read-onlyinherited

A representation of the runtime type of the object.

inherited
isAccessibleIn(LibraryElement library) → bool
Return true if this element, assuming that it is within scope, is accessible to code in the given library. This is defined by the Dart Language Specification in section 6.2:
