AstVisitor<R> class Null safety

An object that can be used to visit an AST structure.

Clients may not extend, implement or mix-in this class. There are classes that implement this interface that provide useful default behaviors in package:analyzer/dart/ast/visitor.dart. A couple of the most useful include

  • SimpleAstVisitor which implements every visit method by doing nothing,
  • RecursiveAstVisitor which will cause every node in a structure to be visited, and
  • ThrowingAstVisitor which implements every visit method by throwing an exception.
