  List<Map<String, dynamic>>? productNames;
  late List<Map<String, dynamic>> productDescriptions;

  void fetchProducts() async {

      setState(() {
        // getElement takes the address of html tag/element and attributes you want to scrap from website
        // it will return the attributes in the same order passed
        productNames = webScraper.getElement(
            'div.thumbnail > div.caption > h4 > a.title', ['href', 'title']);
