我使用的是Go Router，它在开发模式下运行得非常好。在/下启动Web应用程序或使用/abc/def?var刷新也可以。当我使用flutter build web构建应用程序并在docker容器中启动nginx时，当我请求根目录以外的目录时，会得到404。
main.dart:

final GoRouter _router = GoRouter(
  initialLocation: '/me',
  errorBuilder: (context, state) {
    return const Page404();
  },
  routes: <RouteBase>[
    GoRoute(
      name: 'root',
      path: '/:tabid',
      builder: (BuildContext context, GoRouterState state) {
        return NavBarPage(tabId: state.params['tabid']!);
      },
      routes: <RouteBase>[
        GoRoute(
          name: 'blog',
          path: ':blogid/:title',
          builder: (BuildContext context, GoRouterState state) {
            return BlogDefault(blogId: state.params['blogid']!);
          },
        ),
      ],
    ),
  ],
);
