ConstructorDeclaration class Null safety

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 ('.' name)?

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

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

read-onlyinherited
constKeyword Token?
Return the token for the 'const' keyword, or null if the constructor is not a const constructor.
read-only
declaredElement 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.
read-onlyoverride
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.
read-onlyoverride

Return the documentation comment associated with this node, or null if this node does not have a documentation comment associated with it.
read-onlyinherited
end int
Return the offset of the character immediately following the last character of this node's source range.
read-onlyinherited
endToken Token
Return the last token included in this node's source range.
read-onlyinherited
externalKeyword Token?
Return the token for the 'external' keyword to the given token.
read-only

read-onlyinherited
metadata NodeList<Annotation>
Return the annotations associated with this node.

Return the parameters associated with the constructor.
read-only
parent AstNode?

Return the token for the period before the constructor name, or null if the constructor being declared is unnamed.
read-only
redirectedConstructor ConstructorName?
Return the name of the constructor to which this constructor will be redirected, or null if this is not a redirecting factory constructor.
read-only
returnType Identifier
Return the type of object being created.

Methods

accept<E>(AstVisitor<E> visitor) → E?
Use the given visitor to visit this node.
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.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
inherited
setProperty(String name, Object? value) → void
Set the value of the property with the given name to the given value. If the value is null, the property will effectively be removed.
inherited
thisOrAncestorMatching<E extends AstNode>(bool predicate(AstNode)) → E?
Return either this node or the most immediate ancestor of this node for which the predicate returns true, or null if there is no such node.
inherited
thisOrAncestorOfType<E extends AstNode>() → E?
Return either this node or the most immediate ancestor of this node that has the given type, or null if there is no such node.
inherited
toSource() String
Return a textual description of this node in a form approximating valid source.
inherited
toString() String
A string representation of this object.
inherited
visitChildren(AstVisitor visitor) → void
Use the given visitor to visit all of the children of this node.
