AppImage is a great packaging format for Linux, it allows creating a portable bundle that can be executed in almost every GNU/Linux distribution. It keeps the developer (you) in control of the libraries that are used by your app at runtime and it doesn't require anything to be installed previously in order to install your app.
I'm the developer of appimage-builder and would gladly help you making an AppImage recipe for flutter apps.
