public BlockBase::buildConfigurationForm(array $form, FormStateInterface $form_state)
Creates a generic configuration form for all block types. Individual block plugins can add elements to this form by overriding BlockBase::blockForm(). Most block plugins should not override this method unless they need to alter the generic form elements.
