It seems like $this->pool->getItem($this->sanitizeCacheKey($this->prefix . $class)) of type Psr\Cache\CacheItemInterface is incompatible with the declared type Psr\Cache\CacheItemPoolInterface of property $lastItem.

        return $this->lastItem->get();
    }

        $key = $this->sanitizeCacheKey($this->prefix . $metadata->name);

        if (null === $this->lastItem || $this->lastItem->getKey() !== $key) {

The method getKey() does not exist on Psr\Cache\CacheItemPoolInterface.

            $this->lastItem = $this->pool->getItem($key);

It seems like $this->pool->getItem($key) of type Psr\Cache\CacheItemInterface is incompatible with the declared type Psr\Cache\CacheItemPoolInterface of property $lastItem.

        }

        $this->pool->save($this->lastItem->set($metadata));

The method set() does not exist on Psr\Cache\CacheItemPoolInterface.

It seems like $this->lastItem->set($metadata) can also be of type Psr\Cache\CacheItemPoolInterface; however, parameter $item of Psr\Cache\CacheItemPoolInterface::save() does only seem to accept Psr\Cache\CacheItemInterface, maybe add an additional type check?
