For all its benefits in security, performance, and openness, the Linux operating system is still avoided by many computer users because of its software catalog. It's not that Linux lacks app but it lacks the sort of apps that people are used to on Windows and Mac or even on Android and iOS. There is no shortage of projects that try to bring some sort of compatibility with those apps, like WINE for Windows and Anbox for Android. A different strategy, however, is writing apps in a way that makes them run on all or most platforms. That's the premise behind Flutter and it's now coming to Linux, at least on the Ubuntu flavor of Linux.
