如何强制pageView刷新更改页面？

Question

我已经实现了pageView，并且在一个方案中，我希望在更改此页面时刷新页面。

如何实现这一目标？

我的页面是我的页面浏览量课。

这是我的代码，

child: PageView(
                        physics: const NeverScrollableScrollPhysics(
                            parent: BouncingScrollPhysics()),
                        onPageChanged: (page) {
                          setState(() {
                            currentIndex = page;
                          });
                        },
                        scrollDirection: Axis.horizontal,
                        controller: pageController,
                        children: widget.noAccount == null
                            ? [
                                const NoConnectionWidgetHandler(
                                    child: PartyPage()),
                                const NoConnectionWidgetHandler(
                                    child: ClubsPage()),
                                const QrCamera(),
                                const NoConnectionWidgetHandler(
                                    child: FriendsPage()),
                                const NoConnectionWidgetHandler(
                                    child: ProfilePage()),
                              ]

void changePage(int page, BuildContext context) async {
    FocusScope.of(context).unfocus();
    if (page == 2) {
      Provider.of<QrProvider>(context, listen: false)
          .changeCameraVisibility(true);
    } else if (Provider.of<QrProvider>(context, listen: false).isQrCameraOn) {
      Provider.of<QrProvider>(context, listen: false)
          .changeCameraVisibility(false);
    }
    print('previous $currentIndex');
    if (currentIndex == 0) {
      print('wysyłam statystyki o kliknietych eventach');
      var stats = await MySecureStorage().readData('stats_event');
      print('arr: $stats');
      if (stats != null) {
        // send data
      }
      await MySecureStorage().deleteData('stats_event');
    }
    else if (currentIndex == 1) {
      print('wysyłam statystyki o kliknietych partyspotach');
      var stats = await MySecureStorage().readData('stats_partyspots');
      print('arr: $stats');
      if (stats != null) {
        // send data
      }
      await MySecureStorage().deleteData('stats_partyspots');
    }
    if (currentIndex + 1 == page || currentIndex - 1 == page) {
      currentIndex = page;
      pageController.animateToPage(page,
          duration: const Duration(milliseconds: 300), curve: Curves.ease);
    } else {
      currentIndex = page;
      pageController.jumpToPage(page);
    }
    print('current $currentIndex');
  }

这是我的Partypage类，其状态小部件，这是我要刷新的部分：

child: Consumer<ControllerProvider>(
                      builder: (context, shower, child) {
                        return FutureBuilder<List>(
                          future: _loadingList,
                          builder: (BuildContext context, AsyncSnapshot snapshot) {
                            print(snapshot.connectionState);
                            if (snapshot.hasData && snapshot.data.length >= 1) {
                              return LoadingIfNotSatisfied(
                                rebuildIfChanged: Provider.of<MainProvider>(
                                  context,
                                  listen: false,
                                ).isConnectedToInternet,
                                isSatisfied: snapshot.data.isNotEmpty,

                                    //TODO uncomment after pagination on events is fixed
                                    pageNumber += 1;
                                    setState(() {
