Page Router does not corespond with graphical

[fredykoci]

Hi I wrote this pagerouter, but sometimes the callback is not fired, I try to debug but the code works as is but not the visualisation do not show given objects

class Router:
    """
    Class that handle with all views in the app, necessary for changing views
    """

    def __init__(self, page):
        self.page = page
        self.ft = ft
        setting_screen = SettingScreen(page)
        tester_screen = TestScreen(page)
        result_screen = ResultScreen(page)
        config_view = ConfigView()
        test_view = TestView()
        check_screen = CheckScreen(page)
        result_view = ResultView()
        main_page = MainPage()
        check_test_screen = CheckNewTestScreen()
        help_page = HelpPage()
        self.routes = {
            "/": main_page,
            "/TEST": check_test_screen,
            "/RESULT": result_view,
            "/RESULT/check": result_screen,
            "/add": config_view,
            "/TEST/add": tester_screen,
            "/TEST/check": check_screen,
            "/TEST/signpost": check_test_screen,
            "/HELP": help_page,
        }
        # self.page.add(self.routes['/'])

    def route_change(self, route):
        """
        Callback that is fired every time when user want to change view
        :param route: str route to page
        """
        self.page.controls.pop() if len(self.page.controls) > 0 else None
        self.page.update()
        self.routes[route.route].clear_element()
        self.page.overlay.append(*self.routes[route.route].overlay) if len(
            self.routes[route.route].overlay) > 0 else None
        self.page.appbar = self.routes[route.route].appbar
        self.page.add(self.routes[route.route])
        self.page.update()
        print(self.page.controls)
