I'm new to Magento2 and finding it difficult to get information. I'm trying to read simple (variants) products of a configurable product on the view page.
I created my custom block that extends AbstractProduct.
Then I was able to get upsell product ids like this:
$product = $this->_coreRegistry->registry('product');
$upSellProductIds = $product->getUpSellProductIds();
Now, how to get variants(simple products).
In Magento 1.x, I used getUsedProductCollection()
Please help
