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
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
expression Expression
Return the expression to be evaluated for the value to be converted into a string.
read-only
hashCode int
The hash code for this object.
read-onlyinherited
isSynthetic bool
Return true if this node is a synthetic node.
read-onlyinherited
leftBracket Token
Return the token used to introduce the interpolation expression; either '$' if the expression is a simple identifier or '${' if the expression is a full expression.
read-only
length int
Return the number of characters in the syntactic entity's source range.
read-onlyinherited
offset int
Return the offset from the beginning of the file to the first character in the syntactic entity.
read-onlyinherited
parent AstNode?
Return this node's parent node, or null if this node is the root of an AST structure.
read-onlyinherited
rightBracket Token?
Return the right curly bracket, or null if the expression is an identifier without brackets.
read-only
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

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.
