是的，课程后面会用FutureBuilderl来等HiCache.preInit()初始化完成后在进行下一步操作：

class _BiliAppState extends State<BiliApp> {
  BiliRouteDelegate _routeDelegate = BiliRouteDelegate();

  @override
  Widget build(BuildContext context) {
    return FutureBuilder<HiCache>(
        //进行初始化
        future: HiCache.preInit(),
        builder: (BuildContext context, AsyncSnapshot<HiCache> snapshot) {
          //定义route
          var widget = snapshot.connectionState == ConnectionState.done
              ? Router(routerDelegate: _routeDelegate)
              : Scaffold(
                  body: Center(child: CircularProgressIndicator()),
                );

          return MaterialApp(
            home: widget,
            theme: ThemeData(primarySwatch: white),
          );
        });
  }
}

目前用 getInstance().get('xxx').then((value){ setState((){ Xxxx = value }); });
