flutter - 在 AutoTabsRouter 和嵌套的 Scaffolds 中 Flutter NestedScrollView 和 SliverAppBar 作为子级不起作用？

Question

这是我的代码。当我向下滚动时，Appbar 保持静止。如果您需要更多代码，请告诉我。

我正在使用 auto_route 颤振，并且路由 InvestHomeRouter() 和 BonusHomeRouter() 导致其他没有自己的 appbar 并且具有 singleChildScrollviews 作为主体的脚手架。

如果子脚手架检测到任何向下滚动，我希望父脚手架隐藏 appbar。

class Home extends StatelessWidget {
  `const Home({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return SafeArea(
        child: AutoTabsRouter(
            routes: [
          InvestHomeRouter(),
          BonusHomeRouter()
        ],
            builder: (context, child, animation) {
             
              final tabsRouter = AutoTabsRouter.of(context);
              
              return HomeScaffold(
                tabsRouter: tabsRouter,
                child: child,
                animation: animation,
              );
            }));
  }
}

class HomeScaffold extends StatefulWidget {
  HomeScaffold(
      {required this.tabsRouter,
      required this.animation,
      required this.child,
      Key? key})
      : super(key: key);

  final Widget child;
  final Animation<double> animation;
  final TabsRouter tabsRouter;
  @override
  State<HomeScaffold> createState() => _HomeScaffoldState();
}

class _HomeScaffoldState extends State<HomeScaffold> {
  int activeIndex = 0;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: NestedScrollView(
        floatHeaderSlivers: true,
        headerSliverBuilder: (context, innerBoxIsScrolled) => [
          SliverAppBar(
            floating: true,

            ],
          ),
        ],
        body: FadeTransition(
            opacity: widget.animation,
            child: widget.child),
      ),

    );
  }
