Question

Actually I need to Create a Helper Class in Magento2 then Call ProductRepository in

app/code/{vendor}/{module}/Helper/Data.php

to load Product details by sku and return Product Details in cart page and display

app/code/{vendor}/{module/view/frontend/templates/cart/item/default.phtml

Answer 1

First, you have to create a Helper file

Custom\Module\Helper\Data.php

<?php
namespace Custom\Module\Helper;

/**
 * Custom Helper for Load Products 
 */
class Data extends \Magento\Framework\App\Helper\AbstractHelper
{
    protected $productRepository;

    public function __construct(
        \Magento\Catalog\Api\ProductRepositoryInterface $productRepository
    ) {
        $this->productRepository = $productRepository;
    }

    public function loadMyProduct($sku)
    {
        return $this->productRepository->get($sku);
    }
}
?>

Then you can call this helper in your phtml file like below:

$customHelper = $this->helper('Custom\Module\Helper\Data');
$product = $customHelper->loadMyProduct($sku);
