GenericFunctionType class abstract final

An anonymous function type.

functionType ::= TypeAnnotation? 'Function' TypeParameterList? FormalParameterList '?'?

where the FormalParameterList is being used to represent the following grammar, despite the fact that FormalParameterList can represent a much larger grammar than the one below. This is done in order to simplify the implementation.

parameterTypeList ::= () | ( normalParameterTypes ,? ) | ( normalParameterTypes , optionalParameterTypes ) | ( optionalParameterTypes ) namedParameterTypes ::= { namedParameterType (, namedParameterType)* ,? } namedParameterType ::= TypeAnnotation? SimpleIdentifier normalParameterTypes ::= normalParameterType (, normalParameterType)* normalParameterType ::= TypeAnnotation SimpleIdentifier? optionalParameterTypes ::= optionalPositionalParameterTypes | namedParameterTypes optionalPositionalParameterTypes ::= normalParameterTypes ,?

Implemented types




beginToken Token
The first token included in this node's source range.
no setterinherited
childEntities Iterable<SyntacticEntity>
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
end int
The offset of the character immediately following the last character of this node's source range.
no setterinherited
endToken Token
The last token included in this node's source range.
no setterinherited
functionKeyword Token
The Function keyword.
no setter
hashCode int
The hash code for this object.
no setterinherited
isSynthetic bool
Whether this node is a synthetic node.
no setterinherited
length int
Return the number of characters in the syntactic entity's source range.
no setterinherited
offset int
Return the offset from the beginning of the file to the first character in the syntactic entity.
no setterinherited
parameters FormalParameterList
The parameters associated with the function type.
no setter
parent AstNode?
Returns this node's parent node, or null if this node is the root of an AST structure.
no setterinherited
question Token?
The question mark indicating that the type is nullable, or null if there's no question mark.
no setterinherited
returnType TypeAnnotation?
The return type of the function type being defined, or null if no return type was given.
no setter
root AstNode
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
type DartType?
The type being named, or null if the AST structure hasn't been resolved.
no setterinherited
typeParameters TypeParameterList?
The type parameters for the function type, or null if the function type doesn't have any type parameters.
no setter


accept<E>(AstVisitor<E> visitor) → E?
Use the given visitor to visit this node.
findPrevious(Token target) Token?
Returns the token before target, or null if it can't be found.
getProperty<E>(String name) → E?
Returns the value of the property with the given name, or null if this node doesn't have a property with the given name.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
setProperty(String name, Object? value) → void
Set the value of the property with the given name to the given value.
thisOrAncestorMatching<E extends AstNode>(bool predicate(AstNode)) → E?
Returns either this node or the most immediate ancestor of this node for which the predicate returns true, or null if there's no such node.
thisOrAncestorOfType<E extends AstNode>() → E?
Returns either this node or the most immediate ancestor of this node that has the given type, or null if there's no such node.
toSource() String
Returns a textual description of this node in a form approximating valid source.
toString() String
A string representation of this object.
visitChildren(AstVisitor visitor) → void
Use the given visitor to visit all of the children of this node.


operator ==(Object other) bool
The equality operator.
