Yes, that was my conclusion a few months ago. I'm currently working on an Android app, and even though I published the Flutter app in "record time", the drawback is the amount of mental energy needed to make certain platform tasks work.

Background execution was the biggest for me, I didn't want to write a Flutter plugin that interacts with a background service (because even though that's now possible, it still feels confusing to me).

Simple(r) app, Flutter's very good at that. I'll see what happens post 1.0
