It seems like $this->barcodes can also be of type null; however, parameter $haystack of in_array() does only seem to accept array, maybe add an additional type check?

            throw new \InvalidArgumentException("Barcode: $barcode already exists.");
        }
        $this->barcodes[] = $barcode;
        return $this;
