//CategoryDetailScreen arguments holder class
class CategoryDetailScreenArguments {

      @required this.selectedCategory,
      @required this.gradient});
}

“ExtendedNavigator”在工作之前显示为错误： 在此处输入图像描述

然后我有“hasInvalidArgs”和“misTypedArgsRoute”，它们显示为错误： 在此处输入图像描述

最后我有“unknownRoutePage”，它也不再起作用： 在此处输入图像描述

如果有人可以帮助我，那就太好了:)我已经寻找解决方案好几天了，但我找不到任何东西：/
