HttpStatus
const gone
410 Gone
This response is sent when the requested content has been permanently deleted from the server, with no forwarding address. Clients are expected to remove their caches and links to the resource. The HTTP specification intends this status code to be used for "limited-time, promotional services". APIs should not feel compelled to indicate resources that have been deleted with this status code.
Implementation
static const gone = HttpStatus(410);
