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.

"Flet" mobile app must be updated and republished.

@FeodorFitsner can I help with this subject?

Checking class Page I identified a difference between drawer and the others Offstages:

Ex: Banner:

   def show_banner(self, banner: Banner):
        self.__offstage.banner = banner
        self.__offstage.banner.open = True
        self.__offstage.update()

    async def show_banner_async(self, banner: Banner):
        self.__offstage.banner = banner
        self.__offstage.banner.open = True
        await self.__offstage.update_async()

And now Drawer:

    def show_drawer(self, drawer: NavigationDrawer):
        self.drawer = drawer
        self.drawer.open = True
        self.update()

    async def show_drawer_async(self, drawer: NavigationDrawer):
        self.drawer = drawer
        self.drawer.open = True
        await self.update_async()

Why aren't you using __offstage?

I apologize if this has already been reviewed.

Best regards!
