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

no setter
exceptionType → TypeAnnotation?
Return the type of exceptions caught by this catch clause, or null if this catch clause catches every type of exception.
no setter
hashCode → int
The hash code for this object.
no setterinherited
isSynthetic → bool
Return true if this node is a synthetic node.

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 or null if it cannot be found.
inherited
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.
inherited
noSuchMethod(Invocation invocation) → dynamic

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

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
visitChildren(AstVisitor visitor) → void
