I’m trying to run a Flutter app in kiosk mode on a Raspberry Pi 4B, but I’m having trouble getting it to launch in full-screen mode.

I’ve followed the instructions from the Raspberry Pi Kiosk Mode Tutorial to set up kiosk mode, but these steps seem more geared toward running a web app or a website rather than a standalone Flutter app. Even though I tried to adapt those instructions for my Flutter app, it still doesn’t open in full-screen mode.

Here are the steps I took:
Installed necessary packages:

sudo apt install wtype

Configured Raspberry Pi using raspi-config to boot to the graphical interface.

Edited the wayfire.ini file to autostart my Flutter app:

sudo nano .config/wayfire.ini

Added the following lines to the [autostart] section:

    [autostart]
panel = wfrespawn wf-panel-pi
background = wfrespawn pcmanfm --desktop --profile LXDE-pi
xdg-autostart = lxsession-xdg-autostart
flutterapp = /home/downloads/mydemoapp --kiosk --noerrdialogs --disable-infobars --no-first-run --ozone-platform=wayland --enable-features=OverlayScrollbar --start-maximized
screensaver = f

I am able to autostart my app using these steps, but it does not open in full-screen mode as I intended. Does anyone know how I can get my Flutter app to run in true kiosk mode or at least in full-screen on boot?
