void onRefresh() {
  //刷新前，分页设置为0
  page = 0;
  loadData().then((resultData) {
    getListData().clear();
    if (ObjectUtil.isNotEmpty(resultData)) {
      getListData().addAll(resultData!);
      //分页加载，增加下页页码
      page++;
    }
    refreshController?.refreshCompleted(resetFooterState: true);
  }).onError((error, stackTrace) {
    printError(info: 'Error => $error \r\n $stackTrace');
    refreshController?.refreshFailed();
