Properties

beginToken → Token
Return the first token included in this node's source range.
no setterinherited
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
covariantKeyword → Token?
The 'covariant' keyword, or null if the keyword was not used.
no setterinherited
declaredElement → ParameterElement?
Return the element representing this parameter, or null if this parameter has not been resolved.
no setterinherited
documentationComment → Comment?
Return the documentation comment associated with this parameter, or null if this parameter does not have a documentation comment associated with it.
no setterinherited
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 setterinherited
hashCode → int
The hash code for this object.
no setterinherited
identifier → SimpleIdentifier?
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.
no setterinherited
isConst → bool
Return true if this parameter was declared with the 'const' modifier.
no setterinherited
isExplicitlyTyped → bool
Indicates whether the parameter has an explicit type.
no setterinherited
isFinal → bool
Return true if this parameter was declared with the 'final' modifier.
no setterinherited
isNamed → bool
Return true if this parameter is a named parameter.
no setterinherited
isOptional → bool
Return true if this parameter is an optional parameter.
no setterinherited
isOptionalNamed → bool
Return true if this parameter is both an optional and named parameter.
no setterinherited
isOptionalPositional → bool
Return true if this parameter is both an optional and positional parameter.
no setterinherited
isPositional → bool
Return true if this parameter is a positional parameter.
no setterinherited
isRequired → bool
Return true if this parameter is a required parameter.
no setterinherited
isRequiredNamed → bool
Return true if this parameter is both a required and named parameter.
no setterinherited
isRequiredPositional → bool
Return true if this parameter is both a required and positional parameter.
no setterinherited
isSynthetic → bool
Return true if this node is a synthetic node.
no setterinherited
keyword → Token?
Return the token representing either the 'final', 'const' or 'var' keyword, or null if no keyword was used.
no setter
length → int
Return the number of characters in the syntactic entity's source range.
no setterinherited
metadata → NodeList<Annotation>
Return the annotations associated with this parameter.
no setterinherited
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.
no setterinherited
offset → int
Return the offset from the beginning of the file to the first character in the syntactic entity.
no setterinherited
parent → AstNode?
Return this node's parent node, or null if this node is the root of an AST structure.
no setterinherited
requiredKeyword → Token?
The 'required' keyword, or null if the keyword was not used.
no setterinherited
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
sortedCommentAndAnnotations → List<AstNode>
Return a list containing the comment and annotations associated with this parameter, sorted in lexical order.
no setterinherited
type → TypeAnnotation?
Return the declared type of the parameter, or null if the parameter does not have a declared type.
no setter

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 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. 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.
