CupertinoPushPredictiveBackBuilder class

Slides pages in and out like iOS (CupertinoPageTransition) on push and pop, and plays Android's predictive back animation while the user swipes back.

PredictiveBackPageTransitionsBuilder only animates the swipe itself. Every other push or pop gets a fixed fade-forwards transition that can't be changed. This builder keeps the predictive swipe and uses the Cupertino slide for everything else:

• Push, back button, Navigator.pop: Cupertino slide from the right, with the previous page moving left underneath. No fade.
• Back swipe (Android 14+): the predictive back animation, driven by the gesture.

MaterialApp(
  theme: ThemeData(
    pageTransitionsTheme: const PageTransitionsTheme(
      builders: <TargetPlatform, PageTransitionsBuilder>{
        TargetPlatform.android: CupertinoPushPredictiveBackBuilder(),
        TargetPlatform.iOS: CupertinoPageTransitionsBuilder(),
      },
    ),
  ),
)

Use it for Android. On iOS keep CupertinoPageTransitionsBuilder, which adds the iOS edge swipe to go back. This builder leaves that swipe out because it competes with Android's back gesture.
