Flutter's philosophy of drawing everything by itself is how you get so many apps that feel "off", disconnected from the platforms on which they reside.

This is especially true on iOS, which is pretty much a second-class citizen in the Flutter-verse.

Or when Google updates Android 13 to support things like system-wide color preferences and accents in Material You. Only your app can't do any of that until all of those widgets have been updated to support it.
