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

class TaskController extends AbstractType
{
public function new()
{
    // creates a task object and initializes some data for this example       
    $formFactory = Forms::createFormFactory();
    $form = $formFactory->createBuilder()
        ->add('task', TextType::class)
        ->add('dueDate', DateType::class)
        ->add('save', SubmitType::class, ['label' => 'Create Task'])
        ->getForm();

    $loader = new \Twig\Loader\FilesystemLoader('vista/parte');
    $twig = new \Twig\Environment($loader, ['debug' => true]);                
    return $twig->render('foms.html.twig', ['form' => $form->createView()]);       
}
}

(new TaskController())->new();

You are missing few things here.

Controller and form types are two separate things. You can create your form in your controller, and then pass it to the view.

However if you want to separate your form from your controller, you can create a form type that will extend AbstractType

This should look like this:

class TaskController extends AbstractController // add the use for that one
{
    public function new()
    {
        $form = $this->createFormBuilder()
            ->add('task', TextType::class)
            ->add('dueDate', DateType::class)
            ->add('save', SubmitType::class, ['label' => 'Create Task'])
            ->getForm();

        return $twig->render('foms.html.twig', ['form' => $form->createView()]);       
    }
}
