linkFunction method Null safety

  1. @override
Linkable? linkFunction(
  1. FutureOr<RequestOrResponse?> handle(
    1. Request request
    )
)
override

Links a function controller to the receiver to form a request channel.

If the receiver does not respond to a request, handle receives the request next.

See link for a variant of this method that takes an object instead of a closure.

Implementation

@override
Linkable? linkFunction(
  FutureOr<RequestOrResponse?> Function(Request request) handle,
) {
  throw ArgumentError(
    "Invalid link. 'Router' cannot directly link to functions. Use 'route'.",
  );
}
