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 ,?

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

Methods

accept<E>(AstVisitor<E> visitor) → E?
Use the given visitor to visit this node.
inherited
findPrevious(Token target) → Token?
Returns the token before target, or null if it can't be found.
inherited
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.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent 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.
inherited
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.
inherited
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.
inherited
toSource() → String
Returns a textual description of this node in a form approximating valid source.
inherited
toString() → String
