update to dart sass

[nelhop]

With an up do date sass loader this deprecation warning is fired:

Deprecation Warning: Using / for division outside of calc() is deprecated and will be removed in Dart Sass 2.0.0.

Recommendation: math.div($layout-spacing--default, pow($layout-spacing--ratio, 5)) or calc($layout-spacing--default / pow($layout-spacing--ratio, 5))

Underlying the initial error, a switch to dart-sass is in order, because dart-sass is deprecated.

The dependency rfs is not updated yet and will need to be updated in future: twbs/rfs#363

Looking good. Just unsure if this can break older projects using und-css. If you need this as a hot fix feel free to merge.

If not I'd suggest to also get rid of rfs (replacing it with something like utopia.fyi) before bumping to 1.0.0

[lucasdinonolte]

Nice. Unsure though if this will break older projects using und-css that are still in node-sass.

I would consider adding sass as a peer dependency as well and doing a major version of und-css (1.0.0) so yarn won't install this version into an older project by accident.

[lucasdinonolte]

I'm not familiar with SASS' latest changes. Is this the way to do it now?

[nelhop]

Apparently. This is the solution that worked after a quick research.

[lucasdinonolte]

Just make sure to also update the Changelog before merging

[nelhop]

Doing a mayor version sounds like a good idea.

[lucasdinonolte]

Looking good to me! 👍🏻

Thanks so much for this. I'll merge and use this as the basis for the other things needed towards a 1.0 release.
