How do you properly implement platform specific navigation transition animations, ensuring page transitions genuinely feel authentically native on both iOS's characteristic sliding transition and Android's own distinctly different transition style?

Flutter's default page transition behavior already automatically adapts somewhat based on the current specific platform when using standard Material navigation, but building a genuinely fully adaptive app sometimes requires more deliberately explicit control, such as using CupertinoPageRoute specifically on iOS to guarantee that characteristic native sliding transition animation, while using a completely different, standard MaterialPageRoute specifically on Android, and properly and carefully testing these platform specific transition animations on both actual target platforms helps meaningfully ensure the resulting overall navigation experience genuinely feels authentically native and correct on each one respectively.

Platform.isIOS
  ? CupertinoPageRoute(builder: (context) => DetailScreen())
  : MaterialPageRoute(builder: (context) => DetailScreen());
