如何将自定义参数/属性从twig模板传递到自定义表单字段？

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;

class CustomFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            // 添加自定义的表单字段，例如自定义的属性字段
            ->add('custom_property', TextType::class, [
                'label' => 'Custom Property',
                'required' => false,
                'attr' => [
                    'class' => 'custom-property-field'
                ],
            ]);
    }

    public function getParent()
    {
        // 返回所需扩展的表单字段类型，例如要扩展的字段为text字段
        return TextType::class;
    }
}

{% form_theme form _self %}

{% block custom_property_widget %}
    {% set attr = attr|merge({'data-custom-property': custom_property}) %}
    {{ block('form_widget_simple') }}
{% endblock %}

{{ form(form, {
    'widgets': {
        'custom_property': {
            'block': 'custom_property_widget',
            'custom_property': 'Custom Value'
        }
    }
}) }}
