deleteLastInstalledDefinition example

// An entity type can be deleted even when its live (in-code) definition has     // been removed from the codebase, so we need to instantiate a custom     // storage handler that uses the passed-in entity type definition.     $storage = $this->entityTypeManager->createHandlerInstance($entity_type->getStorageClass(), $entity_type);

    // @todo Forward this to all interested handlers, not only storage, once     // iterating handlers is possible: https://www.drupal.org/node/2332857.     if ($storage instanceof EntityTypeListenerInterface) {
      $storage->onEntityTypeDelete($entity_type);
    }

    $this->entityLastInstalledSchemaRepository->deleteLastInstalledDefinition($entity_type_id);

    $this->eventDispatcher->dispatch(new EntityTypeEvent($entity_type), EntityTypeEvents::DELETE);
    $this->clearCachedDefinitions();
  }
