I had the same problem，Is there any solution?

I couldn't use PostCSS 8 because of this but with PostCSS 7 this issue doesn't exist.

Hello,
same problem here, did someone find a way to solve that ??
What is the right config in package.json ??

Hi @GeromeF, we didn't find a solution for this. As this repo is no longer maintained, we've migrated to postcss-rtlcss, as it also uses rtlcss, the migration was straightforward and excepting an issue that we are having with the values of the variables that are not being flipped, it works perfectly.

If someone wants to solve this with this package, here you can find a pull request and a forked package that solves this issue.
