Http response status code constants

Question

I'm building a client side app (in the browser) and I can't find if there exists a list of Http response status codes somewhere.

All the libraries seem to use numbers like 404, 200, etc.. but I find it not too readable.

Is there a standardized place where I could use something like NOT_FOUND for 404 and other constants for other codes?

I've seen Shelf.response that provides factory methods for this, but it's also only usable on the Dart vm if I'm not mistaken.

Answer 1

It is only available in dart:io but not in dart:html.
