I'm trying to get the stock quantity of an item in the cart in Magento CE 2.2.5. To do so, I'm injecting \Magento\CatalogInventory\Api\StockRegistryInterface into \Magento\Checkout\Block\Cart\Item\Renderer so I can create a function that will get the quantity of an item.
However, any function created in this custom module simply does return any data to the frontend. If I create a function like
public function testReturn() {
return 'Test!';
}and try to echo it in the cart by using
<?= $block->testReturn(); ?>
nothing at all is displayed. I've cleared the cache, run bin/magento setup:di:compile, and rebooted the dev server. Any idea on where I'm going wrong? Full code follows below.
