Could I ask what feature they were looking for? I haven't used Flutter in a while, but it left a good impression. I remember being far less annoyed using Flutter than I am using other declarative frameworks like SwiftUI.
I’m an embedded C guy, so you’ll have to forgive my ignorance on this. All this high level stuff is magic to me.
But I want to say it was something larger than a conditional style or pattern matching and probably a state management framework. IDK, I had a good laugh about it and moved on.
EDIT: As to good impression, yes, we’re very happy with Flutter.
