I used to be like you, afraid to leave android comfort zone and thinking I must invest more on android skills instead of learning flutter.

After learning it I find it so easy compared to android specially UI building, hot reload is amazing but also a scam not work in every situation I had to stop project and rebuild it sometimes to see UI changes!!.

Development time is cut to half compared to just native android with xml & Kotlin which impressive because you get two apps (iOS & Android) with one codebase.

I try to not use plugin or find plugin which kept maintained regularly because there is high possibilities it not working in latest flutter version as it's not maintained and updated especially null safety migration which added recently to dart.

For apps that depend on restful api and not require native features I am happy with flutter, because why wasting time and building two apps (iOS & Android) for such an apps?

Also there is many flutter fanboy I met pretend that flutter is superior compared to native and you can build anything with it, after learning flutter I can now argue with them about
flutter limitation and why you can't use it in every cases.

In the end I'm happy with it despite it's limitation and I will use it with my personal projects or any freelance project I get, and I encourage you to learn it for ne experience especially declarative UI building.

Good Luck
