buildPageTransitions<T> method

Widget buildPageTransitions <T>(
  1. PageRoute<T> route,
  2. BuildContext context,
  3. Animation<double> animation,
  4. Animation<double> secondaryAnimation,
  5. Widget child

Returns a CupertinoFullscreenDialogTransition if route is a full screen dialog, otherwise a CupertinoPageTransition is returned.

Used by CupertinoPageRoute.buildTransitions.

This method can be applied to any PageRoute, not just CupertinoPageRoute. It's typically used to provide a Cupertino style horizontal transition for material widgets when the target platform is TargetPlatform.iOS.
