Initialize a newly created method declaration. Either or both of the
comment
andmetadata
can benull
if the declaration does not have the corresponding attribute. The externalKeyword can benull
if the method is not external. The modifierKeyword can benull
if the method is neither abstract nor static. ThereturnType
can benull
if no return type was specified. The propertyKeyword can benull
if the method is neither a getter or a setter. The operatorKeyword can benull
if the method does not implement an operator. Theparameters
must benull
if this method declares a getter.
Properties
- beginToken → Token
-
Return the first token included in this node's source range.
no setterinherited
- body ↔ FunctionBodyImpl
-
Return the body of the method.
getter/setter pairoverride-getter
-
childEntities
→ Iterable<
SyntacticEntity> -
Return an iterator that can be used to iterate through all the entities
(either AST nodes or tokens) that make up the contents of this node,
including doc comments but excluding other comments.
no setterinherited
- declaredElement ↔ ExecutableElement?
-
Return the element associated with this method, or
null
if the AST structure has not been resolved. The element can either be aMethodElement
, if this represents the declaration of a normal method, or aPropertyAccessorElement
if this represents the declaration of either a getter or a setter.getter/setter pairoverride-getter - declaredElement2 → ExecutableElement?
-
Return the element associated with this declaration, or
null
if either this node corresponds to a list of declarations or if the AST structure has not been resolved.no setteroverride - documentationComment ↔ CommentImpl?
-
Return the documentation comment associated with this node, or
null
if this node does not have a documentation comment associated with it.getter/setter pairinherited - end → int
-
Return the offset of the character immediately following the last
character of this node's source range.
no setterinherited
- endToken → Token
-
Return the last token included in this node's source range.
no setteroverride
- externalKeyword → Token?
-
The token for the 'external' keyword, or
null
if the constructor is not external.final - firstTokenAfterCommentAndMetadata → Token
-
Return the first token following the comment and metadata.
no setteroverride
- hashCode → int
-
The hash code for this object.
no setterinherited
- isAbstract → bool
-
Return
true
if this method is declared to be an abstract method.no setteroverride - isGetter → bool
-
Return
true
if this method declares a getter.no setteroverride - isOperator → bool
-
Return
true
if this method declares an operator.no setteroverride - isSetter → bool
-
Return
true
if this method declares a setter.no setteroverride - isStatic → bool
-
Return
true
if this method is declared to be a static method.no setteroverride - isSynthetic → bool
-
Return
true
if this node is a synthetic node.no setterinherited - length → int
-
Return the number of characters in the syntactic entity's source range.
no setterinherited
-
metadata
→ NodeListImpl<
AnnotationImpl> -
Return the annotations associated with this node.
no setterinherited
- modifierKeyword → Token?
-
The token representing the 'abstract' or 'static' keyword, or
null
if neither modifier was specified.final - name → Token
-
Return the name of the method.
final
- name2 → Token
-
Return the name of the method.
no setteroverride
-
namedChildEntities
→ Iterable<
ChildEntity> -
Return properties (tokens and nodes) of this node, with names, in the
order in which these entities should normally appear, not necessary in
the order they really are (because of recovery).
no setterinherited
- offset → int
-
Return the offset from the beginning of the file to the first character in
the syntactic entity.
no setterinherited
- operatorKeyword → Token?
-
The token representing the 'operator' keyword, or
null
if this method does not declare an operator.final - parameters ↔ FormalParameterListImpl?
-
Return the parameters associated with the method, or
null
if this method declares a getter.getter/setter pairoverride-getter - parent → AstNode?
-
Return this node's parent node, or
null
if this node is the root of an AST structure.no setterinherited - propertyKeyword → Token?
-
The token representing the 'get' or 'set' keyword, or
null
if this is a method declaration rather than a property declaration.final - returnType ↔ TypeAnnotationImpl?
-
Return the return type of the method, or
null
if no return type was declared.getter/setter pairoverride-getter - root → AstNode
-
Return the node at the root of this node's AST structure.
no setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
sortedCommentAndAnnotations
→ List<
AstNode> -
Return a list containing the comment and annotations associated with this
node, sorted in lexical order.
no setterinherited
- typeParameters ↔ TypeParameterListImpl?
-
Return the type parameters associated with this method, or
null
if this method is not a generic method.getter/setter pairoverride-getter
