It's not just about the look, it's about the feel.

From looking at the "gallery app" on android:

Flutter's input-text has their own custom mark text handler - no double tap, long press opens a custom menu that is missing native options (Such as translate text).

Changing the font size in the OS does nothing in the app.

Clicking on buttons doesn't make a tap sound if the "sound on tap" option is set.

I'm guessing no accessibility support - or very poor one.

There's probably many more tiny issues that customer's will complain about when you a product is shipped to production that will make it clear that this isn't a native app.

A lot of those are things we've fixed since we published that app. We're just not very good about publishing updates to the play store. I'll see if we can get an update out soon.

Thanks for your feedback! I opened https://github.com/flutter/flutter/issues/12438 to track the "not playing a sound when tapped". We're currently working on improving our accessibility support.
