flutter pull_to_refresh 结合getx报
Don’t use one refreshController to multiple SmartRefresher,It will cause some unexpected bugs mostly in TabBarView ‘package:pull_to_refresh_flutter3/src/smart_refresher.dart’: Failed assertion: line 548 pos 12: '_refresherState == null
一般这种问题，是因为 Getx的每个GetxController 要对应SmartRefresher 各自独立RefreshController ， 如果相同的 我的GetxController 要加tag区分，我的每个GetX对应各自的refreshController，GetxController 是各自的，Getx也加了Tag个，按理说不会有这个问题，正常打开使用没问题，但是当用户按了back键后，在快速点击ListView必报这个，代码如下

  ///外部传参RefreshController
  RefreshController? refreshController;

  ///子类，必须是ListView-ScrolleView等
  Widget? child;

  @override
  Widget build(BuildContext context) {
    return ScrollConfiguration(
        behavior: OverScrollBehavior(),
        child: SmartRefresher(
            key: key,
            controller: refreshController ?? controller.refreshController,
            enablePullDown: enablePullDown,
            enablePullUp: enablePullUp,
            onRefresh: () => controller.onLoadRefresh(),
            onLoading: () => controller.onLoadMore(),
            header: ClassicHeader(

最终解决办法
，因为我页面退出有个300 毫秒的 退出动画，A页面跳转B页面，B页面按了返回键，要退出的一霎那这时候点了B页面，其实是点了A页面，又进入了B,导致Getx持有refreshController 数据紊乱，修改方法 A页面跳转B时加个isClickable 为false ,返回时等待500毫秒才能点击A

  return GestureDetector(
      onTap: () async {
        final nftController = Get.find<NftController>();

        // 防止快速点击pull_to_refresh 出现bug
        if (!nftController.isClickable.value) {
          return;
        }

        // 禁用点击事件
        nftController.isClickable.value = false;

        // 导航到详情页面
        await toDetails();

        // 等待动画结束（假设动画时间为500ms）
        await Future.delayed(const Duration(milliseconds: 500));

        // 重新启用点击事件
        nftController.isClickable.value = true;
      },

  Future toDetails() async {
    await Get.toNamed(AppRoutes.assetsDetailPage, arguments: {
      GetArgumentsKey.walletModel: controller.walletModel,
      GetArgumentsKey.addressModel: controller.addressModel,
      GetArgumentsKey.coinModel: controller.coinModel,
      GetArgumentsKey.model: model,
    });
  }
