I'm still new at Magento and im trying to work on something where I need to pass the product SKU from a file that has a function that retrieves the product SKU to another file with no such function, within the same Module.
In the first file Vendor_name/Module_name/Block/Catalog/Product/File_name.php, a function exists that retrieves a SKU like so:
$sourceItems = $getSourceItemsBySkuInstance->execute((string)$product->getSku());
But, in the other file, located in, Vendor_name/Module_name/Block/File_name.php, no such function exists.
So, how can I pass the
$product->getSku() with its value to the 2nd file?
