endToken Token
Return the last token included in this node's source range.

An expression e is said to occur in a constant context, [...]
read-only, inherited
isAssignable bool
Return true if this expression is syntactically valid for the LHS of an AssignmentExpression.
read-only, inherited
isSynthetic bool
Return true if this node is a synthetic node. [...]
read-only, inherited
length int
Return the number of characters in the syntactic entity's source range.
read-only, inherited
offset int
Return the offset from the beginning of the file to the first character in the syntactic entity.
read-only, inherited
parent AstNode?
Return this node's parent node, or null if this node is the root of an AST structure. [...]
read-only, inherited
precedence Precedence
Return the precedence of this expression. [...]
read-only, inherited
root AstNode
Return the node at the root of this node's AST structure. [...]

runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
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-only, inherited
staticType DartType?
Return the static type of this expression, or null if the AST structure has not been resolved.
@Deprecated('Clients should not build AST manually'), read / write, inherited
unParenthesized Expression
If this expression is a parenthesized expression, return the result of unwrapping the expression inside the parentheses. Otherwise, return this expression.

accept<E>(AstVisitor<E> visitor) → E?
Use the given visitor to visit this node. [...]
findPrevious(Token target) Token?
Return the token before target or null if it cannot be found.
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.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent 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. If the value is null, the property will effectively be removed.
thisOrAncestorMatching<E extends AstNode>(Predicate<AstNode> predicate) → 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.
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.
toSource() String
Return 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. [...]
