help with android studio

I have a problem with this code: ###################################################### Widget build(BuildContext context) { TranslateType translate = [login to view URL](context)!.translate; List<int> ids = product?.upsellIds. ?? []; if ([login to view URL]) { return Container(); } return ProductListView( ids: ids, keyStore: 'upsell_product', title: translate('product_upsell'), padding: padding, align: align, ); } } ########################################################### The problem is that when there is upsell products but they are out of stock, a block appear with the title and no products, i would like to hide it also when there is upsell products but they are out of stock. below the variables of the products: ################################################# dynamic toVariable(String variable) { switch (variable) { case 'id': return id; case 'name': return name; case 'slug': return slug; case 'type': return type; case 'status': return status; case 'sku': return sku; case 'stock_status': return stockStatus; case 'categories': return categories?.map((e) => '${e?.id}').toList() ?? []; default: return ''; } } ############################################### stockStatus can be 'instock' or 'outofstock' to fix it we should verify the stockstatus of these ids how to do it ?
