- Implemented types
Constructors
Properties
- aliasedElement → Element?
-
If the aliased type has structure, return the corresponding element.
For example it could be GenericFunctionTypeElement.
no setter
- aliasedType → DartType
-
Return the aliased type.
no setter
-
children
→ List<
Element> -

There is no guarantee of the order in which the children will be included.
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.

- isPrivate → bool
-
Return
true
if this element is private. Private elements are visible only within the library in which they are declared.no setterinherited - 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.no setterinherited - 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.
no setterinherited
- 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.no setterinherited - kind → ElementKind

If this target is associated with a library, return the source of the
library's defining compilation unit; otherwise return
null
.no setterinherited - location → ElementLocation?
-
Return an object representing the location of this element in the element
model. The object can be used to locate this element at a later time.
no setterinherited
-
metadata
→ List<
ElementAnnotation> -
Return a list containing all of the metadata associated with this element.
The array will be empty if the element does not have any metadata or if
the library containing this element has not yet been resolved.

Return the analysis session in which this element is defined.
no setterinherited

-
The version where this SDK API was added.
no setterinherited
- source → Source
-
Return the source associated with this target, or
null
if this target is not associated with a source.no setterinherited -
typeParameters
→ List<
TypeParameterElement> -
Return a list containing all of the type parameters declared by this
element directly. This does not include type parameters that are declared
by any enclosing elements.

accept<
T> (ElementVisitor< T> visitor) → T? -

presented to users.
inherited
-
getExtendedDisplayName(
String? shortName) → String -
Return a display name for the given element that includes the path to the
compilation unit in which the type is defined. If
shortName
isnull
then displayName will be used as the name of this element. Otherwise the provided name will be used.inherited -
instantiate(
{required List< DartType> typeArguments, required NullabilitySuffix nullabilitySuffix}) → DartType -
Produces the type resulting from instantiating this typedef with the given
typeArguments
andnullabilitySuffix
. -
isAccessibleIn(
LibraryElement library) → bool -
Return
true
if this element, assuming that it is within scope, is accessible to code in the givenlibrary
. This is defined by the Dart Language Specification in section 6.2:inherited -
isAccessibleIn2(
LibraryElement library) → bool -
Return
true
if this element, assuming that it is within scope, is accessible to code in the givenlibrary
. This is defined by the Dart Language Specification in section 6.2:inherited -

Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited

thisOrAncestorMatching<
E extends Element> (bool predicate(Element)) → E? -
Return either this element or the most immediate ancestor of this element
for which the
predicate
returnstrue
, ornull
if there is no such element.inherited -
thisOrAncestorOfType<
E extends Element> () → E? -
Return either this element or the most immediate ancestor of this element
that has the given type, or
null
if there is no such element.inherited -

) → String -
A string representation of this object.
inherited
-
visitChildren(
ElementVisitor visitor) → void -

visitor
to visit all of the children of this element. There is no guarantee of the order in which the children will be visited.inherited
Operators
