show<T> static method

Future<T?> show<T>({ required BuildContext context, required Widget child, String? title, String? subtitle, List<PrismSheetAction<T>> actions = const [], bool isScrollControlled = true, bool isDismissible = true, bool useSafeArea = true, double maxDialogWidth = 460, Widget? header, bool showDragHandle = true, Color? backgroundColor, })

Shows the adapted surface and resolves with the value passed to Navigator.pop — either from an action, a drag-dismiss (null) or the barrier (null).
