我有两个嵌套的路由：

GoRoute(
            parentNavigatorKey: _homePageShellNavigatorKey,
            name: MenuScreen.routeName,
            path: '/menu_screen',
            pageBuilder: (_, state) {
              assert(
                state.extra is MenuScreenArgs || state.extra == null,
                'extra of menu_screen route should be null or have a type of MenuScreenArgs,'
                ' but instead got ${state.extra.runtimeType}',
              );
              return MaterialPage(
                child: MenuScreen(
                  args: state.extra as MenuScreenArgs?,
                ),
              );
            },
            routes: [
              GoRoute(
                parentNavigatorKey: _rootNavigatorKey,
                name: CoffeeDetailsScreen.routeName,
                path: 'coffee_details_screen',
                pageBuilder: (_, state) {
                  assert(
                    state.extra != null &&
                        state.extra is CoffeeDetailsScreenArgs,
                    'extra of coffee_details_screen route should have a type of'
                    ' CoffeeDetailsScreenArgs,'
                    ' but instead got ${state.extra.runtimeType}',
                  );
                  return MaterialPage(
                    child: CoffeeDetailsScreen(
                      args: state.extra as CoffeeDetailsScreenArgs,
                    ),
                  );
                },
              ),
              GoRoute(
               // ... another nested route
              ),
            ],
          ),

字符串

• 如果我在，比如说主屏幕，并转到menu_screen，那么menu_screen路由的页面构建器被调用，Assert通过，没有错误
• 如果我在menu_screen中调用这段代码，那么coffee_details_screen被成功推送，但是menu_screen和coffee_details_screen的pageBuilder都被调用：

CoffeeDetailsScreen.routeName,
                extra: CoffeeDetailsScreenArgs(productId: product.id),
              );

型

• 如果我现在在coffee_details_screen中，我打开flutter devtools并按下select widget，并且我还在menu_screen和coffee_details_screen的'pageBuilder'上放置断点，那么我注意到它们都被调用了，但是当menu_screen builder被调用时，它被传递了错误的args，它被传递了coffee_details_screen的args，这使得Assert失败：

assert(
                state.extra is MenuScreenArgs || state.extra == null,
                'extra of menu_screen route should be null or have a type of MenuScreenArgs,'
                ' but instead got ${state.extra.runtimeType}',
              );

为什么会发生这种情况，是我使用路由器时的错误还是什么问题？
