100% Agreed. When I was evaluating what platform to develop on, I found Flutter and it checked off all the right boxes on paper. So I started to write an app in it and soon discovered the checks are absolutely real. I can't imagine that it works for 100% of the use cases, but if you're developing a relatively simple mobile app... Flutter is the way to go. Dart is lovely to work in and the API is strangely similar to SwiftUI. ;-)

I also filed a bug about tests in Dart not being able to be code folded properly in IDEA and it was fixed within about a month. The developers of that plugin really take it seriously. Totally awesome.
