Properties

keyword Token
Return the token representing either the 'final', 'const' or 'var' keyword, or null if no keyword was used.
read / write
parameters FormalParameterList
Return the parameters of the function-typed parameter, or null if this is not a function-typed field formal parameter.
read / write
period Token
Return the token representing the period.
read / write
question Token
If the parameter is function-typed, and has the question mark, then its function type is nullable. Having a nullable function type means that the parameter can be null.
read-only
thisKeyword Token
Return the token representing the 'this' keyword.
read / write
type TypeAnnotation
Return the declared type of the parameter, or null if the parameter does not have a declared type. [...]
read / write
typeParameters TypeParameterList
Return the type parameters associated with this method, or null if this method is not a generic method.
read / write
beginToken Token
Return the first token included in this node's source range.
read-only, inherited
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.
read-only, inherited
covariantKeyword Token
The 'covariant' keyword, or null if the keyword was not used.
read / write, inherited
declaredElement ParameterElement
Return the element representing this parameter, or null if this parameter has not been resolved.
read-only, inherited
documentationComment Comment
Return the documentation comment associated with this parameter, or null if this parameter does not have a documentation comment associated with it.
read / write, inherited
end → int
Return the offset of the character immediately following the last character of this node's source range. [...]
read-only, inherited
endToken Token
Return the last token included in this node's source range.
read-only, inherited
hashCode → int
The hash code for this object.
read-only, inherited
identifier SimpleIdentifier
Return the name of the parameter being declared.
read / write, inherited
isConst → bool
Return true if this parameter was declared with the 'const' modifier.
read-only, inherited
isFinal → bool
Return true if this parameter was declared with the 'final' modifier. [...]
read-only, inherited
isNamed → bool
Return true if this parameter is a named parameter. [...]
read-only, inherited
isOptional → bool
Return true if this parameter is an optional parameter. [...]
read-only, inherited
isOptionalNamed → bool
Return true if this parameter is both an optional and named parameter.
read-only, inherited
isOptionalPositional → bool
Return true if this parameter is both an optional and positional parameter.
read-only, inherited
isPositional → bool
Return true if this parameter is a positional parameter. [...]
read-only, inherited
isRequired → bool
Return true if this parameter is a required parameter. [...]
read-only, inherited
isRequiredNamed → bool
Return true if this parameter is both a required and named parameter. [...]
read-only, inherited
isRequiredPositional → bool
Return true if this parameter is both a required and positional parameter.
read-only, inherited
isSynthetic → bool
Return true if this node is a synthetic node. [...]
read-only, inherited
kind ParameterKind
Return the kind of this parameter.
read-only, inherited
length → int
Return the number of characters in the syntactic entity's source range.
read-only, inherited
metadata NodeList<Annotation>
Return the annotations associated with this parameter.
read / write, inherited
offset → int
Return the offset from the beginning of the file to the first character in the syntactic entity.
read-only, inherited
parent AstNode
Return this node's parent node, or null if this node is the root of an AST structure. [...]
read-only, inherited
requiredKeyword Token
The 'required' keyword, or null if the keyword was not used.
read-only, inherited
root AstNode
Return the node at the root of this node's AST structure. [...]
read-only, inherited
runtimeType → Type
A representation of the runtime type of the object.
read-only, inherited
sortedCommentAndAnnotations → List<AstNode>
Return a list containing the comment and annotations associated with this parameter, sorted in lexical order.

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>(Predicate<AstNode> predicate) → 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<T extends AstNode>() → T

inherited
toSource() → String
Return a textual description of this node in a form approximating valid source. [...]
inherited
toString() → String
Returns a string representation of this object.
inherited
visitChildren(AstVisitor visitor) → void
Use the given visitor to visit all of the children of this node. [...]
