This module acts as a framework for form building kits. It allows you to load an existing form, add pre-defined form elements like text fields and submit buttons, and then return the modified form.

public function buildForm(array $form, FormStateInterface $form_state) {
  $factory = $this->formFactoryService->load($form);
  $k = $this->formFactoryKitsService;

  $factory->append($k->text())
    ->append($k->submit());

  return $factory->getForm();
}
