GenericFunctionTypeImpl class
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 ,?

Constructors
- GenericFunctionTypeImpl({required TypeAnnotationImpl? returnType, required Token functionKeyword, required TypeParameterListImpl? typeParameters, required FormalParameterListImpl parameters, required Token? question})
- Initialize a newly created generic function type.
Properties
- beginToken → Token
-
Return the first token included in this node's source range.
no setteroverride
-
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 ↔ GenericFunctionTypeElement?
-
Return the element associated with the function type, or
null
if the AST structure has not been resolved.getter/setter pair - 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
- functionKeyword → Token
-
Return the keyword 'Function'.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- 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
-
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
- parameters ↔ FormalParameterListImpl
-
Return the parameters associated with the function type.
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 - question → Token?
-
The question mark indicating that the type is nullable, or
null
if there is no question mark.final - returnType ↔ TypeAnnotationImpl?
-
Return the return type of the function type being defined, or
null
if no return type was given.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
- type ↔ DartType?
-
Return the type being named, or
null
if the AST structure has not been resolved.getter/setter pairoverride-getter - typeParameters ↔ TypeParameterListImpl?
-
Return the type parameters for the function type, or
null
if the function type does not have any type parameters.getter/setter pairoverride-getter
Methods

accept<
E> (AstVisitor< E> visitor) → E? -
Use the given
visitor
to visit this node.override -
detachFromParent(

findPrevious(
Token target) → Token? -
Return the token before
target
ornull
if it cannot be found.inherited -
getProperty<
E> (String name) → E? -
Return the value of the property with the given
name
, ornull

Invoked when a nonexistent method or property is accessed.
inherited
-
setProperty(
String name, Object? value) → void -

which the
predicate
returnstrue
, ornull
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(

Return a textual description of this node in a form approximating valid
source.
inherited
-
toString(
