Properties

beginToken → Token
The first token included in this node's source range.
no setterinherited
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
correspondingParameter → FormalParameterElement?
The parameter element representing the parameter to which the value of this expression is bound.
no setterinherited
element → MethodElement2?
The element associated with the expression based on the static types.
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
index → Expression
The expression used to compute the index.
no setter
isAssignable → bool
Whether this expression is syntactically valid for the LHS of an AssignmentExpression.
no setterinherited
isCascaded → bool
Whether this expression is cascaded.
no setter
isNullAware → bool
Whether this index expression is null aware (as opposed to non-null).
no setter
isSynthetic → bool
Whether this node is a synthetic node.
no setterinherited
leftBracket → Token
The left square bracket.
no setter
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
period → Token?
The period (".." | "?..") before a cascaded index expression, or null if this index expression isn't part of a cascade expression.
no setter
precedence → Precedence
The precedence of this expression.
no setterinherited
question → Token?
The question mark before the left bracket, or null if there's no question mark.
no setter
realTarget → Expression
The expression used to compute the object being indexed.
no setter
rightBracket → Token
The right square bracket.
no setter
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
staticElement → MethodElement?
The element associated with the expression based on the static types, or null if the AST structure hasn't been resolved, or there's no meaningful static element to return. The latter case can occur, for example, when this is a non-compound assignment expression, or when the method referred to couldn't be resolved.
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 expression used to compute the object being indexed, or null if this index expression is part of a cascade expression.
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

Methods

accept<E>(AstVisitor<E> visitor) → E?
Use the given visitor to visit this node.
inherited
findPrevious(Token target) → Token?
Returns the token before target, or null if it can't be found.
inherited
inGetterContext() → bool
Returns true if this expression is computing a right-hand value (that is, if this expression is in a context where the operator '[]' is invoked).
inSetterContext() → bool
Returns true if this expression is computing a left-hand value (that is, if this expression is in a context where the operator '[]=' is invoked).
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
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.
inherited
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.
inherited
toSource() → String
Returns 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.

Operators

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