如何将两个不同的对象类型传递到单个页面，以便我可以忽略所需的任何一个：
发件人：

onTap: () {
Navigator.push(
context, PageTransition(
alignment: Alignment.bottomRight,
type: PageTransitionType.fade,
child: CategoryDetail(
topCategories: categories[i])));
}

OR

Navigator.of(context).push(PageTransition(
alignment: Alignment.bottomRight,
type: PageTransitionType.fade,
child: CategoryDetail(category: categories[i])));

收件人：

class CategoryDetail extends StatefulWidget {
CategoryDetail({Key? key, required this.topCategories, required this.category})
  : super(key: key);

final Category category;
final TopCategories topCategories;

@override
State<CategoryDetail> createState() => _CategoryDetailState();
}
