Try something like below in your observer file.


namespace Custom\Module\Observer;

use Magento\Framework\Event\ObserverInterface;

class SalableObserver implements ObserverInterface

    protected $dataHelper;


    public function __construct(
        \Custom\Module\Helper\Data $dataHelper
    ) {
        $this->dataHelper = $dataHelper;

    public function ...(){
        $helper = $this->dataHelper;
