Constructors
Properties
- context → AnalysisContext
-
Return the analysis context in which this element is defined.
no setterinherited
- declaration → VariableElement
-
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 setteroverride
- 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 → Element?

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.no setterinherited - enclosingElement2 → Element?

element. This will be
null
if this element is a library because libraries are the top-level elements in the model.no setterinherited - enclosingElement3 → Element?
-
Return the element that either physically or logically encloses this
element. This will be

no setterinherited
- isConst → bool

Return
true
if this variable was declared with the 'const' modifier.no setter - isConstantEvaluated → bool
-
Return whether this constant is evaluated.
no setterinherited
- isFinal → bool
-
Return
true
if this variable was declared with the 'final' modifier. Variables that are declared with the 'const' modifier will returnfalse
even though they are implicitly final.no setter - isLate → bool
-
Return
true
if this variable uses late evaluation semantics.no setter - 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 - isStatic → bool
-
Return
true
if this element is a static variable, as per section 8 of the Dart Language Specification:no setter - 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
-
Return the kind of element that this is.
no setterinherited
- library → LibraryElement?
-
Return the library that contains this element. This will be the element
itself if it is a library element. This will be
null
if this element is MultiplyDefinedElement that is not contained in a library.no setterinherited - librarySource → Source?
-
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?

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.
no setterinherited

null
if this element does not have a name.no setteroverride - nameLength → int
-

-
Return the offset of the name of this element in the file that contains
the declaration of this element, or
-1
if this element is synthetic, does not have a name, or otherwise does not have an offset.no setterinherited - nonSynthetic → Element
-
Return the non-synthetic element that caused this element to be created.
no setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- session → AnalysisSession?
-
Return the analysis session in which this element is defined.
no setterinherited
- source → Source?
-
Return the source associated with this target, or
null
if this target is not associated with a source.no setterinherited - type → DartType
-
Return the declared type of this variable.
no setter
Methods
-
accept<
T> (ElementVisitor< T> visitor) → T? -
Use the given
visitor
to visit this element. Return the value returned by the visitor as a result of visiting this element.inherited -
computeConstantValue(
) → DartObject? -
Return a representation of the value of this variable, forcing the value
to be computed if it had not previously been computed, or
null
if either this variable was not declared with the 'const' modifier or if the value of this variable could not be computed because of errors. -
getDisplayString(
{required bool withNullability, bool multiline = false}) → String -
Return the presentation of this element as it should appear when
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 -
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 3.2: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 -
noSuchMethod(
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 -
toString(
) → 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
