Unknown module flashlight

[Andrukva]

Question

When running on a physical device, it gives the error "unknown flashlight module" and also swears at lambda. I use Python 3.12.4 and Android 7. Please tell me how to fix it? Thank you in advance.

Code sample

import flet as ft

def main(page: ft.Page):
    flashLight = ft.Flashlight()
    page.overlay.append(flashLight)
    page.add(
        ft.TextButton("toggle", on_click: lambda _: flashlight.toggle())
    )

ft.app(target=main)

Error message

No response

once check and request android.permission.FLASHLIGHT permission OLD VERSION API

import flet as ft


def main(page: ft.Page):
    flashLight = ft.Flashlight()
    page.overlay.append(flashLight)

    def flashLight_toggled(e):
        flashLight.toggle(wait_timeout=5)

    page.add(
        ft.ElevatedButton(
            text="toogle",
            on_click=flashLight_toggled
        )
    )


ft.app(target=main)

in flutter:
The following codes work in flutter. Flet gives error: error, api used must be higher than 23

bool _onn= false;

  void _onoff() async{
    try {
      final isTorchAvailable = await TorchLight.isTorchAvailable();
      if (isTorchAvailable){
        if(!_onn){
          TorchLight.enableTorch();
          _onn=true;
        }
        else{
          TorchLight.disableTorch();
          _onn=false;
        }

      }
    } on Exception catch (_) {
      // Handle error
    }
  }
