CascadeExpression class abstract final

A sequence of cascaded expressions: expressions that share a common target.

There are three kinds of expressions that can be used in a cascade expression: IndexExpression, MethodInvocation and PropertyAccess.

cascadeExpression ::= Expression cascadeSection*

cascadeSection ::= ('..' | '?..') (cascadeSelector arguments*) (assignableSelector arguments*)* (assignmentOperator expressionWithoutCascade)?

cascadeSelector ::= ' ' expression ' ' | identifier

Implemented types




beginToken Token
The first token included in this node's source range.
no setterinherited
cascadeSections NodeList<Expression>
The cascade sections sharing the common target.
no setter
childEntities Iterable<SyntacticEntity>
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
end int
The offset of the character immediately following the last character of this node's source range.
no setterinherited
endToken Token
The last token included in this node's source range.
no setterinherited
hashCode int
The hash code for this object.
no setterinherited
inConstantContext bool
Whether this expression is in a constant context.
no setterinherited
isAssignable bool
Whether this expression is syntactically valid for the LHS of an AssignmentExpression.
no setterinherited
isNullAware bool
Whether this cascade is null aware (as opposed to non-null).
no setter
isSynthetic bool
Whether this node is a synthetic node.
no setterinherited
length int
Return the number of characters in the syntactic entity's source range.
no setterinherited
nullShortingTermination Expression
The expression that terminates any null shorting that might occur in this expression.
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?
Returns this node's parent node, or null if this node is the root of an AST structure.
no setterinherited
precedence Precedence
The precedence of this expression.
no setterinherited
root AstNode
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
staticParameterElement ParameterElement?
The parameter element representing the parameter to which the value of this expression is bound, or null if any of these conditions are not true
no setterinherited
staticType DartType?
The static type of this expression, or null if the AST structure hasn't been resolved.
no setterinherited
target Expression
The target of the cascade sections.
no setter
unParenthesized Expression
If this expression is a parenthesized expression, returns the result of unwrapping the expression inside the parentheses. Otherwise, returns this expression.
no setterinherited


accept<E>(AstVisitor<E> visitor) → E?
Use the given visitor to visit this node.
findPrevious(Token target) Token?
Returns the token before target, or null if it can't be found.
getProperty<E>(String name) → E?
Returns the value of the property with the given name, or null if this node doesn't have a property with the given name.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
setProperty(String name, Object? value) → void
Set the value of the property with the given name to the given value.
thisOrAncestorMatching<E extends AstNode>(bool predicate(AstNode)) → E?
Returns either this node or the most immediate ancestor of this node for which the predicate returns true, or null if there's no such node.
thisOrAncestorOfType<E extends AstNode>() → E?
Returns either this node or the most immediate ancestor of this node that has the given type, or null if there's no such node.
toSource() String
Returns a textual description of this node in a form approximating valid source.
toString() String
A string representation of this object.
visitChildren(AstVisitor visitor) → void
Use the given visitor to visit all of the children of this node.


operator ==(Object other) bool
The equality operator.
