Flatpak allows the developers to create a complete application package that includes all the required libraries and dependent packages to run the application. The developer just has to build the application once, and then he can use it and run it in any Linux operating system without making a single change. Flatpak applications run completely on their own and do not have to do anything with the system, so it is possible to run the same application on a system multiple times.
Installation
Flatpak is available in the official ubuntu package repository and can easily be installed from there.
