How to use the @material/list/foundation.js function in @material/list

listItemAtIndexHasClass: (index, className) => {
        if (!this.listElement) {
          return false;
        }

        const item = mwcList.getElementAtIndex(this.listElement, index);

        if (!item) {
          return false;
        }

        return mwcListItem.hasClass(item, className);
      },
    };

    this.mdcListFoundation = new MDCListFoundation(mdcListAdapter);
    this.mdcListFoundation.init();
  }
