An index expression.
indexExpression ::= Expression '[' Expression ']'
- Implemented types
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 nottrue
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
, ornull
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

, ornull
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
