link method Null safety

  1. @override
Linkable? link(
  1. Controller generatorFunction(
      )
    )
    override

    Routers override this method to throw an exception. Use route instead.

    Implementation

    @override
    Linkable? link(Controller Function() generatorFunction) {
      throw ArgumentError(
        "Invalid link. 'Router' cannot directly link to controllers. Use 'route'.",
      );
    }
