tailwind prefix

[ithuis]

We have a project that started in bootstrap, no we use tailwind with a prefix so they work together.
unfortunalty flux does not work with tailwind prefix.

so i was looking into possibilties, and this is what i came up with..
It's not done yet, i got to fix the !classes.

But my questions are:

1. is this something thate would bother others?
2. What whould be a good location to configure the prefix? because there is no laravel config.

use Illuminate\Support\Arr;
use Stringable;

class ClassBuilder implements Stringable
{
    protected $pending = [];

    protected $prefix = "tw-";

    public function add($classes)
    {
        $classes = Arr::toCssClasses($classes);

        if (!empty($this->prefix)) {
            $classes = $this->addPrefix($classes, $this->prefix);
        }

        $this->pending[] = $classes;

        return $this;
    }

    public function addPrefix($classes, $prefix = '')
    {
        $classes = array_filter(explode(' ', $classes));

        $classes = array_map(function ($class) use ($prefix) {
            $parts = explode(':', $class);
            $parts[count($parts) - 1] = $prefix . $parts[count($parts) - 1];
            return implode(':', $parts);
        }, $classes);

        return implode(' ', $classes);
    }

    public function __toString()
    {
        return (string) collect($this->pending)->join(" ");
    }
}
