public function isAvailable(\Magento\Quote\Api\Data\CartInterface $quote = null)
{
    if (!$this->isActive($quote ? $quote->getStoreId() : null)) {
        return false;
    }


    $checkResult = new DataObject();
    $checkResult->setData('is_available', true);


    // for future use in observers
    $this->_eventManager->dispatch(
        'payment_method_is_active',
        [
            'result' => $checkResult,
            'method_instance' => $this,
            'quote' => $quote
        ]
    );


    return $checkResult->getData('is_available');
}
