I haven't actually tried it, but when I was getting into Flutter/Dart for a small Android project it seemed like (from what I saw online) it would be very simple to build a web version from the same code that generated the APK. Of course for more intricate apps this would likely not hold true. Had quite a good time with Flutter even if it was just a week of tinkering.
