Great, if theres anything i can help you with, just let me know. I had a look on the code, but just didn't even know where to start looking.

@dbeulen
That's not your fault at all, the whole I/O "subsystem" is a complete mess right now. I tried integrating it all into one function that "does it all" (on_evdev_input) but that wasn't a good choice after all.

Can we have a option to disable multitouch until you fixed the bug to prevent unwanted inputs?

I just now uploaded the fix/touchscreen-input branch (which is based on the feature/video_player_plugin branch) that fixes touchscreen input. I still have to fix orientation on that branch, that's why it isn't merged into master yet. (The touchscreen fix involved basically completely rewriting flutter-pi.c)
You can also use dbeulen's fork which removed multi-touch support, but supports orientation.

We didnt do a very clean job of removing multitouch, but it works for now....

So in first place, thanks both for your work!
@ardera I tried to compile the fix/touchscreen-input branch but always run into the same error.

I never had such problems with the master branch but I am running on the lite version so maybe that's just me missing some packages.

Exactly, you need to have the following additional packages installed: libsystemd-dev, libudev-dev, libinput-dev
The drm.h: No such file or directory error is weird. If it still ocurrs after installing the packages you can try invoking make with the --always-make flag.
The dependency on libudev is another reason why I haven't merged into master yet, udev sadly is not present on all embedded linux devices.

I tried this but haven't put "-dev" behind the requested package name. Just because I'm interested - when does a library get this "-dev" sign?
But with these packages building worked fine until I wanted to start my app. The main project I'm working on just crashed right after starting it:

Output of the default Flutter app was this:

So this has probably something to do with orientation which you said is not implemented yet.
