Constructors
Properties
- beginToken → Token
-
Return the first token included in this node's source range.
no setterinherited
-
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.
no setterinherited
- declaredElement → VariablePatternElement?
-
Return the element associated with this declaration, or
null
if either the variable name is_
(in which case no variable is defined) or the AST structure has not been resolved.no setter - end → int
-
Return the offset of the character immediately following the last
character of this node's source range.
no setterinherited
- endToken → Token
-
Return the last token included in this node's source range.
no setterinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- isSynthetic → bool
-
Return
true
if this node is a synthetic node.no setterinherited - keyword → Token?
-
The 'var' or 'final' keyword used when there is no type, or
null
if a type is given.no setter - length → int
-
Return the number of characters in the syntactic entity's source range.
no setterinherited
- name → Token
-
The name of the variable being bound, if
_
then no variable is bound, and declaredElement isnull
.no setter - offset → int
-
Return the offset from the beginning of the file to the first character in
the syntactic entity.
no setterinherited
- parent → AstNode?
-
Return this node's parent node, or
null
if this node is the root of an AST structure.no setterinherited - precedence → Precedence
-
Return the precedence of this pattern.
no setterinherited
- root → AstNode
-
Return 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
- type → TypeAnnotation?
-
The type that the variable is required to match, or
null
if any type is matched.no setter - unParenthesized → DartPattern
-
If this pattern is a parenthesized pattern, return the result of
unwrapping the pattern inside the parentheses. Otherwise, return this
pattern.

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
ornull
if it cannot be found.inherited -
getProperty<
E> (String name) → E? -
Return the value of the property with the given
name
, ornull
if this node does not have a property with the given name.inherited -

inherited
-
setProperty(
String name, Object? value) → void -

. If the value isnull
, 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
returnstrue
, ornull
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
-

visitor
to visit all of the children of this node.inherited
Operators
