I try to do it like this ,but it don't work
less-plugin-functions

var lessTransformer = require("react-native-less-transformer");

module.exports.transform = function({ src, filename, options }) {
  if (filename.endsWith(".less")) {
    var opts = Object.assign(options, {
      lessOptions: {
        plugins: [require("less-plugin-functions")]
      }
    });
    return lessTransformer.transform({ src, filename, options: opts });
  } else {
    return upstreamTransformer.transform({ src, filename, options });
  }
};

Thanks @snowlotus! That should work, does it throw some kind of an error?
