Quite honestly, developing for Android and iOS is no longer worth it. I was planning a set of cross-platform native products using Flutter and other tools, but after a careful analysis came to the conclusion that it makes no sense. You have to distribute 5 different apps (Linux, macOS, Windows, iOS, Android) with 5 different packaging, signing, and distribution requirements and have to fight with all kinds of garbage, from Gatekeeper over expensive certificates for Windows to avoid being flagged by antivirus, to anti-competitive app store requirements by Apple and Google.

Web apps have become unavoidable. Native is beating a dead horse.
