navigation drawer does not work on mobile

[xtream-club]

Navigation drawer does not work on mobile. When deploying my application with serious python using navigation drawer it tells me that navigation drawer is not a flutter control and shows an error. I don't know if it hasn't been tested on android yet or what the problem is. But it seems that it does not work on mobile devices at the moment.

Yeah, you're right! Here is what i get:

import flet as ft


def main(page: ft.Page):
    page.drawer = ft.NavigationDrawer(
        controls=[
            ft.Container(height=12),
            ft.NavigationDrawerDestination(
                label="Item 1",
                icon=ft.icons.DOOR_BACK_DOOR_OUTLINED,
                selected_icon_content=ft.Icon(ft.icons.DOOR_BACK_DOOR),
            ),
            ft.Divider(thickness=2),
            ft.NavigationDrawerDestination(
                icon_content=ft.Icon(ft.icons.MAIL_OUTLINED),
                label="Item 2",
                selected_icon=ft.icons.MAIL,
            ),
            ft.NavigationDrawerDestination(
                icon_content=ft.Icon(ft.icons.PHONE_OUTLINED),
                label="Item 3",
                selected_icon=ft.icons.PHONE,
            ),
        ],
    )

    def show_drawer(e):
        page.drawer.open = True
        page.drawer.update()

    page.add(ft.ElevatedButton("Show drawer", on_click=show_drawer))


ft.app(main)

My problem is that if I do it with views, and in a view I add a navigationdrawer I get an error: AssertionError: Control must be added to the page first.

[ErikEgidoBlanes2223]

Friend, did you find any solution?

[baseplate-admin]

Unfortunately nope, i didn’t have time to really dig into this issue.

I will try to, but there might be others who are faster/effective than me

Hello friend, I already found exactly where I have the problem, I am creating a view, I pass a container value to it, and within that container I have all the characteristics of my page, the error is that if I put my navigationdrawer in the container that then it will be inside the view gives me the error experienced.

However, if I add a drawer option to my view I can use it.

Now my problem is that I don't know what to put in the drawer option of ft.View, and I don't know how to add the functionality for when it is clicked and so on.

            page.views.append(
                ft.View(
                    "/home",
                    [
                        page2
                    ],bgcolor="#b1aaa5", scroll=ft.ScrollMode.AUTO, drawer= MyNavigationDrawer
                )
            )

page2 is a object ft.Container, but ft.View I have option drawer.
