flutter-pi.c: Could not query DRM device list: No such file or directory

[hayden-wolfe]

Hi, I've run flutter-pi successfully in the past on a Raspberry Pi 4B running RPiOS Bullseye and Bookworm. I recently got a Pi Zero 2 W and wanted to try flutter-pi on it. I installed RPiOS Bullseye, booted the Pi Zero 2 W, and followed the instructions in the readme exactly.

I built the app using the old build method, by running flutter build bundle on my host machine then scp the build to the Pi. When I run sudo flutter-pi /home/user/testApp, however, I get this error: flutter-pi.c: Could not query DRM device list: No such file or directory

I've tried switching the KMS settings with no luck. Does anyone know how to resolve this error?
