Navigation does not reload instantly on Dart/ Flutter - flutter

Question

I am working on this navigation that is a list but it is very inconstant in refreshing. Sometimes it refreshes and appears the new button, and other times it does not show the new button. Have you had this problem before.
This is my page showing the routers list and the pages list:
class RouterTabletPage extends StatefulWidget { // ignore: must_be_immutable
BuildContext? context;
RouterTabletPage({Key? key}) : super(key: key);
#override
_RouterTabletPageState createState() => _RouterTabletPageState();
}
class _RouterTabletPageState extends State<RouterTabletPage> with SingleTickerProviderStateMixin {
final NavigationController _navigationController = IoC.get<NavigationController>()!;
final TopBarWidgetController _topBarController = IoC.get<TopBarWidgetController>()!;
final TerminalLockController _terminalLockController = IoC.get<TerminalLockController>()!;
final PreAlarmController _preAlarmController = IoC.get<PreAlarmController>()!;
final UpdateUiService _updateUiService = IoC.get<UpdateUiService>()!;
PageController? _pageViewController;
#override
initState() {
super.initState();
WidgetsBinding.instance!.addPostFrameCallback((_) async {
await _navigationController.initRoutes();
_navigationController.pageViewController = PageController(initialPage: _navigationController.menuSelectedIndex);
_pageViewController = _navigationController.pageController;
await _navigationController.getTabs(_navigationController.menuSelectedIndex);
await _navigationController.setListenerPage();
_topBarController.initTopBar();
await _navigationController.refreshCycleBtn();
});
}
registerContext() {
widget.context = context;
_terminalLockController.registerContext(context);
_preAlarmController.registerContext(context);
_updateUiService.registerContext(context);
}
#override
void dispose() {
super.dispose();
}
#override
Widget build(BuildContext context) {
registerContext();
return Observer(
builder: (_) {
return Scaffold(
appBar: _topBarController.topBarWidget,
backgroundColor: Theme.of(context).primaryColor,
body: Container(
color: Theme.of(context).primaryColor,
margin: const EdgeInsets.all(0.0),
child: Row(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Container(
width: 60,
margin: const EdgeInsets.only(top: 0.0),
color: Theme.of(context).primaryColor,
child: Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
mainAxisSize: MainAxisSize.max,
children: _navigationController.tabs,
),
),
Expanded(
child: Container(
color: Theme.of(context).backgroundColor,
child: PageView(
scrollDirection: Axis.vertical,
controller: _pageViewController,
children: _navigationController.pages,
),
And this is my controller:

I have already tried changing WidgetsBinding to Future.delay and tried initiating different ways inside refreshCycleBtn().
