Subject: [PATCH] Fix for Declaration , compatibility .

Error:
Declaration of app\models\Product::getPrice() must be compatible with yii2mod\cart\models\CartItemInterface::getPrice(): int

return type should be defined to fix the incompatibility. Also, PHP version should be greater than  7 in the composer.json.
