public FormBuilder::getForm($form_arg)
Gets a renderable form array.
This function should be used instead of self::buildForm() when $form_state is not needed (i.e., when initially rendering the form) and is often used as a menu callback.
Parameters
\Drupal\Core\Form\FormInterface|string $form_arg: The value must be one of the following:
- The name of a class that implements \Drupal\Core\Form\FormInterface.
- An instance of a class that implements \Drupal\Core\Form\FormInterface.
...: Any additional arguments are passed on to the functions called by \Drupal::formBuilder()->getForm(), including the unique form constructor function. For example, the node_edit form requires that a node object is passed in here when it is called. These are available to implementations of hook_form_alter() and hook_form_FORM_ID_alter() as the array $form_state->getBuildInfo()['args'].
Return value
array The form array.
