ConstructorDeclarationImpl class

A constructor declaration.

constructorDeclaration ::= constructorSignature FunctionBody? | constructorName formalParameterList ':' 'this' ('.' SimpleIdentifier)? arguments

constructorSignature ::= 'external'? constructorName formalParameterList initializerList? | 'external'? 'factory' factoryName formalParameterList initializerList? | 'external'? 'const' constructorName formalParameterList initializerList?

constructorName ::= SimpleIdentifier ('.' SimpleIdentifier)?

factoryName ::= Identifier ('.' SimpleIdentifier)?

initializerList ::= ':' ConstructorInitializer (',' ConstructorInitializer)*

Constructors

ConstructorDeclarationImpl({required CommentImpl? comment, required List<AnnotationImpl>? metadata, required Token? externalKeyword, required Token? constKeyword, required Token? factoryKeyword, required IdentifierImpl returnType, required Token? period, required Token? name, required FormalParameterListImpl parameters, required Token? separator, required List<ConstructorInitializerImpl>? initializers, required ConstructorNameImpl? redirectedConstructor, required FunctionBodyImpl body})
Initialize a newly created constructor declaration. The externalKeyword can be null if the constructor is not external. Either or both of the comment and metadata can be null if the constructor does not have the corresponding attribute. The constKeyword can be null if the constructor cannot be used to create a constant. The factoryKeyword can be null if the constructor is not a factory. The period and name can both be null if the constructor is not a named constructor. The separator can be null if the constructor does not have any initializers and does not redirect to a different constructor. The list of initializers can be null if the constructor does not have any initializers. The redirectedConstructor can be null if the constructor does not redirect to a different constructor. The body can be null if the constructor does not have a body.

Properties

beginToken → Token
Return the first token included in this node's source range.
no setterinherited
body ↔ FunctionBodyImpl
Return the body of the constructor.
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
constKeyword ↔ Token?
The token for the 'const' keyword, or null if the constructor is not a const constructor.
getter/setter pairoverride-getter
declaredElement ↔ ConstructorElement?
The element associated with this constructor, or null if the AST structure has not been resolved or if this constructor could not be resolved.
getter/setter pairoverride-getter
declaredElement2 → ConstructorElement?
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
factoryKeyword → Token?
The token for the 'factory' keyword, or null if the constructor is not a factory constructor.
final

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).

Methods

accept<E>(AstVisitor<E> visitor) → E?
Use the given visitor to visit this node.
override
detachFromParent() → void
inherited
findPrevious(Token target) → Token?
Return the token before target or null if it cannot be found.
inherited
getProperty<E>(String name) → E?
Return the value of the property with the given name, or null if this node does not have a property with the given name.
