group method
Creates a route, and allows you to add child routes to it via a Router instance.
Returns the created route. You can also register middleware within the router.
Implementation
SymlinkRoute<T> group(String path, void Function(Router<T> router) callback,
{Iterable<T> middleware = const [], String name = ''}) {
final router = Router<T>().._middleware.addAll(middleware);
callback(router);
return mount(path, router)..name = name;
}
