Symfony - Add class to form tag

I know I can add classes to <input> fields in a form like this:

->add('foo', 'text', array('attr' => array('class' => 'foo-class'));

but how could I add a class to a <form> tag?

In a form type class (working in Symfony 4+, not sure if in earlier), in setDefaultOptions():

class FooType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('bar')
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults([
            'data_class' => 'App\Entity\Foo',
            'attr' => ['class' => 'custom-css-class']
        ]);
    }
}

For this, there's 2 solutions, either you do it in your controller or your view.

1) In your controller :

$form = $this->createForm(new FormType(), $data, ['attr' => ['class' => 'myClass']]);

2) In your view (Twig) :

{{ form_start(form, { 'attr' : { 'class': 'myClass' } }) }}
