Symfony. How do I pass parameters to Custom Form Field Type?

I have created Custom Form Field Type according to the documentation and it works fine(I mean no errors). I have a class:

<?php

namespace AppBundle\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;

class RangeType extends AbstractType
{
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(

        ));
    }

    public function getParent()
    {
        return RangeType::class;
    }
}

I have a twig template:

{# app/Resources/views/form/fields.html.twig #}
{% block range_widget %}
   <div class="cell-md-12 offset-top-45 offset-md-top-0">
      <div data-min="" data-max="6000" data-start="[9, 2999]" data-step="10" data-tooltip="false" data-min-diff="10" data-input=".rd-range-input-value-2" data-input-2=".rd-range-input-value-3" class="rd-range"></div>
      <hr class="divider divider-offset-lg divider-gray veil reveal-md-block">
    </div>
{% endblock %}

I added that to the config:

# app/config/config.yml
twig:
    form_themes:
        - 'form/fields.html.twig'

and finally I have a code to add the field to the form:

$builder->add('price', RangeType::class, [
                'data'   => $options['priceRange'] ? $options['priceRange'] : $options['minPrice'].",".$options['maxPrice'],
                'attr'=> [
                    'data-min' => $options['minPrice'],
                    'data-max' => $options['maxPrice'],
                    'data-dimension' => $options['dimension']
                ]
            ]);

How do I use that "data", "data-min", "data-max", "data-dimension" options from the form builder in the twig template? So far as you can see all of them are static in the template.

You can access you 'attr' option values by using the folowing path:

form.vars.attr

So, to get the 'data-min' parameter value form example, you'll just need to do:

{% set attr = form.vars.attr %}
<div data-min="{{ attr['data-min'] }}" ...
