AutoTabsScaffold dynamic add

[JamieYee]

 @override
  Widget build(BuildContext context, WidgetRef ref) {
    final accountEnable = ref.watch(configNotifierProvider.select((it) => it.accountEnable));

    final List<PageRouteInfo> routes = [
      HomeRoute(),
      TrendRoute(),
      if(accountEnable)AccountRoute(),
      MineRoute()
    ];

    final tabs = [
      NavigationDestination(icon: Icon(Icons.home), label: 'detail'.tr()),
      NavigationDestination(icon: Icon(Icons.trending_up), label: 'trend'.tr()),
      if(accountEnable)NavigationDestination(icon: Icon(Icons.credit_card), label: 'account'.tr()),
      NavigationDestination(icon: Icon(Icons.person), label: 'mine'.tr()),
    ];

    return AutoTabsScaffold(
      key: _tabsRouterKey,
      routes: routes,
      bottomNavigationBuilder: (_, tabsRouter) {
        return ScrollToHide(
            child: NavigationBar(
                onDestinationSelected: (index) =>
                    tabsRouter.setActiveIndex(index),
                selectedIndex: tabsRouter.activeIndex,
                destinations: tabs),
            height: Platform.isAndroid ? 80.w : 85.w,
            scrollController: _scrollController,
            duration: Duration(milliseconds: 300),
            hideDirection: Axis.vertical);
      },
    );
  }

I control whether accountEnable is turned on in the subpage of MineRoute. If the operation is turned on, then the destinations under AccountRoute are displayed as NavigationDestination(icon: Icon(Icons.person), label: 'mine'.tr()). You need to click other destinations again to return to normal. If it is turned from on to off, there is no problem
