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
hashCode int
The hash code for this object.
read-onlyinherited
inConstantContext bool
An expression e is said to occur in a constant context,
read-onlyinherited
isAssignable bool
Return true if this expression is syntactically valid for the LHS of an AssignmentExpression.
read-onlyinherited
isSynthetic bool
Return true if this node is a synthetic node.
read-onlyinherited
length int
Return the number of characters in the syntactic entity's source range.
read-onlyinherited
nullShortingTermination Expression
Returns the expression that terminates any null shorting that might occur in this expression. This may be called regardless of whether this expression is itself null-aware.
read-onlyinherited
offset int
Return the offset from the beginning of the file to the first character in the syntactic entity.
read-onlyinherited
operand Expression
Return the expression computing the operand for the operator.
read-only
operator Token
Return the postfix operator being applied to the operand.
read-only
parent AstNode?
Return this node's parent node, or null if this node is the root of an AST structure.
read-onlyinherited
precedence Precedence
Return the precedence of this expression.
read-onlyinherited
readElement Element?
The element that is used to read the value.
read-onlyinherited
readType DartType?
The type of the value read with the readElement.
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
staticElement MethodElement?
Return the element associated with the expression based on the static types, or null if the AST structure has not been resolved, or there is no meaningful static element to return (e.g. because this is a non-compound assignment expression, or because the method referred to could not be resolved).
read-onlyinherited
staticParameterElement ParameterElement?
If this expression is an argument to an invocation, and the AST structure has been resolved, and the function being invoked is known based on static type information, and this expression corresponds to one of the parameters of the function being invoked, then return the parameter element representing the parameter to which the value of this expression will be bound. Otherwise, return null.
read-onlyinherited
staticType DartType?
Return the static type of this expression, or null if the AST structure has not been resolved.
read-onlyinherited
unParenthesized Expression
If this expression is a parenthesized expression, return the result of unwrapping the expression inside the parentheses. Otherwise, return this expression.
read-onlyinherited
writeElement Element?
The element that is used to write the result.
read-onlyinherited
writeType DartType?
The types of assigned values must be subtypes of this type.
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.
