我是Flutter和Riverpod新手。我试图存档的是从服务器上获取的项目列表，带有分页和刷新列表选项。分页工作良好，但刷新工作出于某种原因，只有当_page> 1，否则部件不被重建。我现在想弄清楚几个小时了。我可以看到DriverRepository（）.driverJobList（tab，pages，filtering）;被调用，新的数据从JSON中出现。

    final jobListAsyncValue = ref.watch(JobListResponseProvider);

    void _loadMore() {
      if (_scrollController.position.atEdge) {
        if (_scrollController.position.extentAfter < 500) {
          if (_page < _maxPages) {
            ref.read(JobListPaginationProvider.notifier).state = ++_page;
