I'm betting the farm on Flutter. I'm building a relatively complicated app that's integrated with native C code on iOS and Android. Before I decided to go with Flutter/Dart, paradigms that I knew nothing about, I experimented with all of the major frameworks. React Native, Expo, Ionic, Capacitor, etc. I chose Flutter because it had the best performance for what I was doing around high-performance audio. Flutter is allowing me to continuously move forward and make real progress as a solo dev. I'm finding the DX better than React Native. I'm going to need to make a related tvOS app as well, but not sure how well Flutter can support it.
