The flatpak directory can be deleted from the project and be moved to the repo on Flathub by following the app submission instructions, however 2d6c8d7b7879733930790e9e86d2ebea89a6e4ca is required to make the touchscreen scroll work on linux platforms.
With your permission I'd be willing to submit the app on Flathub.
Added support for flatpak https://github.com/LemmurOrg/lemmur/issues/295.

Problems: Linux ARM64 builds (required for Pinephone/Librem5) cannot be automatically built until either https://github.com/flutter/flutter/issues/74929 or https://github.com/actions/runner-images/issues/5631 gets resolved, but in the meantime I could manually compile it myself and add the tar.gz in the releases
