在我的Flutter应用程序中，我使用go_router在页面之间导航。
以下是我的应用程序中的当前页面：

• accounts_page
• add_account_page
• import_accounts_page

现在，我想在add_account_page中实现嵌套导航，这样我就可以使用多个步骤添加一个新帐户，比如：

• account_info_step
• account_type_step
• account_detail_step

下面是我的尝试：

final _navigatorKey = GlobalKey<NavigatorState>();
  final _addAccountNavigatorKey = GlobalKey<NavigatorState>();

  late final router = GoRouter(
    navigatorKey: _navigatorKey,
    initialLocation: "/accounts_page",
    routes: [
      ShellRoute(
        navigatorKey: _addAccountNavigatorKey,
        builder: (context, state, child) => AddAccountPage(child: child),
        routes: [
          GoRoute(
            parentNavigatorKey: _addAccountNavigatorKey,
            name: "account_info_step",
            path: "/account_info_step",
            builder: (context, state) => const AccountInfoStep(),
          ),
          GoRoute(
            parentNavigatorKey: _addAccountNavigatorKey,
            name: "account_type_step",
            path: "/account_type_step",
            builder: (context, state) => const AccountTypeStep(),
          ),
          GoRoute(
            parentNavigatorKey: _addAccountNavigatorKey,
            name: "account_detail_step",
            path: "/account_detail_step",
            builder: (context, state) => const AccountDetailStep(),
          ),
        ],
      ),
      GoRoute(
        name: "accounts_page",
        path: "/accounts_page",
        pageBuilder: (context, state) => const AccountsPage(),
      ),
      GoRoute(
        name: "import_accounts_page",
        path: "/import_accounts_page",
        pageBuilder: (context, state) => const ImportAccountsPage(),
      ),
    ],
  );

然后我调用context.pushNamed("account_info_step")，但是什么也没发生。
那么是否可以使用go_router在add_account_page中实现嵌套导航？如果可以，如何实现？
谢谢。
