  static void bottomSheetDialog(
    BuildContext context,
    Widget widget, {
    bool? isScrollControlled,
    bool? enableDrag,
    Color? backgroundColor,
  }) {
    showModalBottomSheet(
      context: context,
      isScrollControlled: isScrollControlled ?? true,
      enableDrag: enableDrag ?? true,
      backgroundColor: backgroundColor ?? Colors.white,
      builder: (ctx) {
        return widget;
      },
    );
  }
