        routes: <GoRoute>[
          GoRoute(
            path: '/',
            builder: (BuildContext context, GoRouterState state) => HomePage(),
            routes: <GoRoute>[
              GoRoute(
                path: 'profile/:id',
                builder: (BuildContext context, GoRouterState state) {
                  final String id = state.params['id']!.toString();
                  return ProfilePage(id: id);
                },
              ),
            ],
          ),
        ],
        errorPageBuilder: (BuildContext context, GoRouterState state) {
          return Scaffold(
            body: Center(
              child: Text('Error: ${state.error}'),
            ),
          );
        },
        debugLogListenable: _debugLogListenable, // 如果你想看到路由的日志
      ),
      routeInformationParser: GoRouter.routeInformationParser,
      routerDelegate: GoRouter.routerDelegate,
    );
  }
}
 
class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: TextButton(
          child: Text('Go to profile page'),
          onPressed: () {
            // 使用GoRouter进行路由跳转
            GoRouter.of(context).go('/profile/0612');
          },
        ),
      ),
    );
  }
}
 
class ProfilePage extends StatelessWidget {
  final String id;
 
  ProfilePage({required this.id});
 
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Text('Profile Page with ID: $id'),
      ),
    );
  }
}

这个示例代码展示了如何在Flutter应用中使用go\_router插件来处理路由跳转和参数传递。代码中定义了一个主页面HomePage和一个个人资料页面ProfilePage，在HomePage中有一个按钮可以跳转到ProfilePage并传递一个ID参数。使用GoRouter进行路由跳转和参数处理，同时展示了错误页面的自定义构建方法。
