How to use existing Symfony FormType in Sonata Admin Bundle configureFormFields?

SonataAdminBundle gives a method configureFormFields when you extend the Admin class.

That method takes a FormMapper class.

For the entity that I have created this class for, I have already built a FormType class in the typical Symfony fashion.

How can I use that class instead of having to define the form properties again using the FormMapper?

I came across this question looking for the exact same thing and eventually found the following in the docs:

You can add Symfony FormBuilderInterface instances to the FormMapper. This allows you to re-use a model form type. When adding a field using a FormBuilderInterface, the type is guessed.

Given you have a PostType like this: 

use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;
use Symfony\Component\Form\AbstractType;

class PostType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('author', EntityType::class, [
                'class' => User::class
            ])
            ->add('title', TextType::class)
            ->add('body', TextareaType::class)
        ;
    }
}

you can reuse it like this: 

use Sonata\AdminBundle\Form\FormMapper;
use Sonata\AdminBundle\Admin\AbstractAdmin;
use App\Form\PostType;

class Post extend AbstractAdmin
{
    protected function configureFormFields(FormMapper $formMapper)
    {
        $builder = $formMapper->getFormBuilder()->getFormFactory()->createBuilder(PostType::class);

        $formMapper
            ->with('Post')
                ->add($builder->get('title'))
                ->add($builder->get('body'))
            ->end()
            ->with('Author')
                ->add($builder->get('author'))
            ->end()
        ;
    }
}

I had to the exact same thing today (defined a custom form type and tried to use in sonata) after hours of finding a clean way, i came up with this:

formMapper->add('your_field', new YourType($your_params), array(                    
                ), array('type' => 'form'))

Replace your_field with your field name,

new YourType with your custom field type and

$your_params with your field's constructor's parameters,

the fourth parameter array('type' => 'form') is very important, it tells sonata about what type your form is actually (sonata wont determine automatically from your type's object) my custom field extends the form type (it is an embedded form with its own fields) so i specify that, if your type extends something else then specify that, and hopefully it would work fine.

something like:

public function configureFormFields(FormMapper $formMapper)
{        
    $form = new ReviewFormType();
    $form->buildForm($formMapper->getFormBuilder(),array());
}
