Sure, but most common mobile apps ARE completely custom UIs which insist on their own branding and look. The UI designers usually really hate if they have to use standard components and are unable to express themselves.

Flutter just recognises that.

Agreed, most apps I use already don't use native controls, like Slack, Discord, Spotify etc, and I don't want my apps to do so either since I have a custom design. I think people on HN think users care about platform UI when we see that most users really don't notice or care.

That depends on what kind of controls though. Many apps will their own buttons, but most are using the native text input control (and often the native scroll for screens / screen transitions.

On iOS it's not too difficult to build a fully custom UI with just UIKit. You want a totally custom button? No problem, don't fight the styling inherent with UIButton, just subclass its parent class UIControl instead which is a blank canvas, but still gets you 90% of the perks of a standard UIButton with minimal effort. It's pretty easy to write entirely custom widgets with unique behaviors too.

It's a bit more messy to do that with Android Framework, and because of that I see more of an argument for using Flutter there than on iOS. Jetpack Compose seems to be a lot better in that regard though.
