Issue with routing

[Soif2Sang]

Hello, I previously created an issue related to this topic, but I have been unable to find a solution for the issue involving the page disappearing when changing routes.

Below, you will find the code reproduction along with comments describing the behavior. Please note that the "DumbTimer" is included to ensure that the "/:id" clear attribute is not set to True. It will raise an exception otherwise.

import random
import threading
from time import sleep

import flet as ft
from flet_route import path, Routing

class DumbTimer(ft.Text):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.value = 200

    def start(self):
        threading.Thread(target=self.decrease).start()

    def decrease(self):
        self.value -= 1
        self.update()
        sleep(1)
        return self.decrease()

class ContainerLinkedToWheel(ft.ListView):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        direction = str(random.randint(0, 1111))

        self.verification = ft.FilledButton(f"Click to check if the UI is still responsive", on_click=self.verify)

        self.controls.append(self.verification)
        self.controls.append(ft.FilledButton(f'go to /{direction}', on_click=lambda _: self.page.go(f'/{direction}')))

    def verify(self, e):
        self.verification.text += " ok"
        self.update()

class Wheel(ft.Row):
    def __init__(self, page, key, **kwargs):
        super().__init__(**kwargs)
        self.page = page
        self.key = key

        self.button_select = ft.IconButton(
            icon=ft.icons.SETTINGS_OUTLINED,
            selected_icon=ft.icons.SETTINGS,
            on_click=lambda _: self.select()
        )

        self.controls.append(self.button_select)

    def select(self):
        #Pop the container with the buttons too show a new one linked to the clicked wheel

        self.page.wheel_list.unselect_all()
        self.button_select.selected = True

        if len(self.page.controls) > 2:
            # Make the UI unresponsive if clear=False and If I will of wheel
            self.page.controls.pop()
            pass

        # print(self.page.frames)
        if self.key not in self.page.frames:
            self.page.frames[self.key] = ContainerLinkedToWheel(height=200, width=300)

        self.page.add(self.page.frames[self.key])
        self.page.update()

class WheelList(ft.ListView):
    def __init__(self, page, **kwargs):
        super().__init__(**kwargs)
        self.page = page
        self.wheels: dict[str, Wheel] = {}

    def unselect_all(self):
        for wheel in self.controls:
            wheel.button_select.selected = False
        self.update()

    def add_wheel(self, key: str):
        self.wheels[key] = Wheel(self.page, key)
        self.controls.append(self.wheels[key])
        self.update()

def index(page: ft.Page, params, basket):
    return  ft.View("/", controls=page.controls,)

def somewhere(page: ft.Page, params, basket):
    return  ft.View("/" + params.id, controls=[ft.FilledButton('Go back to /', on_click=lambda _: page.go('/'))],)

def main(page:ft.Page):

    page.app_routes = [
        path(url="/", clear=True, view=index),
        path(url="/:id", clear=False, view=somewhere),
    ]

    page.routing = Routing(
        page=page,
        app_routes=page.app_routes,
    )

    page.frames = {}

    #If I use clear=True for "/" route, I can't go from / to somewhere else and twice without exception raising
        #Also, no issues about the UI updating once clicking on any wheel if you don't trigger the exception above, which is 100% normal
    #If I use clear=False I can go on any route no issue until I decide to click on the other wheel which triggers page.controls.pop() and make the UI unresponsive and no exception is raised
    page.go('/')
    dT = DumbTimer()
    page.add(dT)
    dT.start()
    page.wheel_list = WheelList(page)
    page.add(page.wheel_list)
    page.wheel_list.add_wheel('1')
    page.wheel_list.add_wheel('2')


    page.update()

ft.app(target=main)

The only way I found was to create a view that always returns wheel_list and a "place holder" for the wheel container, and replace all self.page = page to self.initial_page = page (i'm avoiding overriding self.page) and replace all self.update() to self.initial_page.update() and avoid self.clean to avoid exception raised because the control is not added to the page (but is actually added to the page)
