The PostCSS 7’ postcss.plugin method has been deprecated in favour of manually created function returning an object containing various event handling functions like Once, Declaration, Rule and many more.

- module.exports = postcss.plugin('postcss-dark-theme-class', (opts = {}) => {
-   checkOpts(opts)
-   return (root, result) => {
      root.walkAtRules(atrule => { … })
-   }
- })
+ module.exports = (opts = {}) => {
+   checkOpts(opts)
+   return {
+     postcssPlugin: 'postcss-dark-theme-class',
+     Once (root, { result }) {
        root.walkAtRules(atrule => { … })
+     }
+   }
+ }
+ module.exports.postcss = true

Thanks, and sorry for the slow resolution! I've merged your PR (manually) and changed the validator to accept both old and new plugins - it's now published as @validatem/is-postcss-plugin 0.1.1.
