flutter-pi VS mmal-sys

Flutter on a bare bone Raspberry Pi sounds interesting but I doubt that this will be come an official additional platform so it's probably just a fun experiment that exists for a couple of years now.

Work done by Canonical with their Desktop Installer, Sonos with the setup sequence, foldable support by Microsoft's Andrei Diaconu, Raspberry PI support and e-ink POC by Simon Lightfoot. The list could go on and on.

I have a RPi 4 with dedicated camera module (with ribbon connector) and I need to access and control this camera using Dart+Flutter. I use flutter-pi (https://github.com/ardera/flutter-pi) but I'm not sure what package/plugin should I use to achieve this task. I found "camera" plugin (https://pub.dev/packages/camera) but it looks like it's more for mobile applications and I'm afraid that it will not work in my case. Is there any preferred way to do this?

First thing to do is to set up the Raspberry Pi. In the README of the flutter-pi repo it's mentioned that flutter-pi should run without Xserver. Therefore I went with a headless version of RaspberryOS. Once you've flashed the os to a ssd card, follow the instructions in the flutter-pi README and install drivers for your touch screen of choice. Be sure to clone the engine-binaries branch of flutter-pi and place the files in the correct directories aswell.

Now that we know how to compile and run Rust and Flutter in conjunction on the rpi we want to be able to control the camera from our app. There might be libraries for controlling the camera written in Dart but since we want to use Rust together with Dart, we're going to do it from Rust. I've chosen a library called rascam. It's a small library built on top of mmal-sys. We can add rascam to our Rust project by adding this to the Cargo.toml file:
