Check out how Magento does it when rendering the caches in vendor/magento/module-backend/Block/Cache/Grid/Column/Statuses.php.

Basically, it injects the \Magento\Framework\App\Cache\TypeListInterface class in constructor and it retrieves the list of invalidated caches by calling the method of the concrete class vendor/magento/framework/App/Cache/TypeList.php which implements the method:

$this->_cacheTypeList->getInvalidated()

  • i am assuming, that using this class & calling this getInvalidated method i will get the invalidated cache types in controller.

  • $output = []; foreach ($this->_cacheTypeList->getInvalidated() as $type) { $output[] = $type->getCacheType(); } return $output;
