Properties

beginToken Token
Return the first token included in this node's source range.
read-onlyinherited
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-onlyinherited
covariantKeyword Token?
The 'covariant' keyword, or null if the keyword was not used.
read-onlyinherited
declaredElement ParameterElement?
Return the element representing this parameter, or null if this parameter has not been resolved.
read-onlyinherited
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-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
hashCode int
The hash code for this object.
read-onlyinherited
isConst bool
Return true if this parameter was declared with the 'const' modifier.
read-onlyinherited
isExplicitlyTyped bool
Indicates whether the parameter has an explicit type.
read-onlyinherited
isFinal bool
Return true if this parameter was declared with the 'final' modifier.
read-onlyinherited
isNamed bool
Return true if this parameter is a named parameter.
read-onlyinherited
isOptional bool
Return true if this parameter is an optional parameter.
read-onlyinherited
isOptionalNamed bool
Return true if this parameter is both an optional and named parameter.
read-onlyinherited
isOptionalPositional bool
Return true if this parameter is both an optional and positional parameter.
read-onlyinherited
isPositional bool
Return true if this parameter is a positional parameter.
read-onlyinherited
isRequired bool
Return true if this parameter is a required parameter.
read-onlyinherited
isRequiredNamed bool
Return true if this parameter is both a required and named parameter.
read-onlyinherited
isRequiredPositional bool
Return true if this parameter is both a required and positional parameter.
read-onlyinherited
isSynthetic bool
Return true if this node is a synthetic node.
read-onlyinherited
keyword Token?
Return the token representing either the 'final', 'const' or 'var' keyword, or null if no keyword was used.
read-only
length int
Return the number of characters in the syntactic entity's source range.
read-onlyinherited
metadata NodeList<Annotation>
Return the annotations associated with this parameter.
read-onlyinherited
name Token
Return the name of the parameter being declared, or null if the parameter doesn't have a name, such as when it's part of a generic function type.
read-onlyoverride
offset int
Return the offset from the beginning of the file to the first character in the syntactic entity.
read-onlyinherited
parameters FormalParameterList?
Return the parameters of the function-typed parameter, or null if this is not a function-typed field formal parameter.
read-only
parent AstNode?
Return this node's parent node, or null if this node is the root of an AST structure.
read-onlyinherited
period Token
Return the token representing the period.
read-only
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
requiredKeyword Token?
The 'required' keyword, or null if the keyword was not used.
read-onlyinherited
root AstNode
Return the node at the root of this node's AST structure.
read-onlyinherited
runtimeType Type
A representation of the runtime type of the object.
read-onlyinherited
sortedCommentAndAnnotations List<AstNode>
Return a list containing the comment and annotations associated with this parameter, sorted in lexical order.
read-onlyinherited
thisKeyword Token
Return the token representing the 'this' keyword.
read-only
type TypeAnnotation?
Return the declared type of the parameter, or null if the parameter does not have a declared type.
read-only
typeParameters TypeParameterList?
Return the type parameters associated with this method, or null if this method is not a generic method.

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.
