What is the current go to solution for cross platform apps?
Expo has been making unbelievably rapid progress with tooling, documentation, consistent, high quality API's and general improvements. Evan Bacon + team are really impressive to watch
1) Need mostly cross platform desktop and using hardware extensively (bluetooth, camera, audio, nfc, sensors, etc.) -> Qt
2) Have web expertise or need easily to find well paid job and need mostly web, android, ios app -> React Native
3) Need only iOS, Android app that is mostly custom UI with some smooth animation mostly for some side project (not many jobs in the market comparing to React Native or iOS/Android Native) -> Flutter
