return AnimatedScreenOverlayHost(
  overlay: _overlay,
  onDismiss: _dismissOverlay,
  overlayBuilder: (context, req, dismiss) => switch (req) {
    DialogRequest(key: 'hello') => AlertDialog(
      title: const Text('Hello'),
      actions: [TextButton(onPressed: dismiss, child: const Text('Close'))],
    ),
    _ => null,
  },
  child: DeclarativePagesNavigator(
    pages: _pages,
    buildPage: _buildPage,
    onPopTop: _popTop,
    canPopTop: () => _overlay == null,
  ),
);

Muhim

Overlay ko'rinib turganda, canPopTop bilan pop gesturelarni bloklang iOS dagi back-swipe nomuvofiqligini oldini olish uchun.
