My states of learning Flutter:

Oh, this looks easy!
Hm, this example is very complicated.
Aw yeah, I'll never need Android Studio again!
How much is a iOS dev account?
Oh for fuck's sake, why is everything working except displaying a webpage in non-fullscreen dynamically and implementing it in my widget tree? It is unusable for me if this doesn't work but I want to use it! >:(

i switched back to android studio from flutter. no regrets. flutter is unstable and there are some features which can not yet be created with flutter compared to native development.

There is still hope. The model of flutter is sound, just needs more time. I also like R.N and would recommend Codename One as well if you enjoy coding in Java or kotlin. The platform is legit af and really easy to use once you get the hang of it. Built a couple of demos, even a uber clone with one of their tutorials and was thoroughly impressed.

One thing that is missing: the arktit from Android, but I ain't using that anytime soon. Try it out man, you might like it.
