有没有人遇到过使用 Web url 直接路由到已知路由的问题。我已经在当前稳定版（2.5.3）中使用非常小的颤振应用程序复制了这一点。举一个简单的路由示例：

initialRoute: '/login',
routes: {
  '/login': (context) => LoginScreen(),
},
onGenerateRoute: (RouteSettings routeSettings) {
  if (routeSettings.name == LoginScreen.routeName) {
    return MaterialPageRoute(
      settings: routeSettings,
      builder: (context) => LoginScreen(),
    );
  }
},
onUnknownRoute: (RouteSettings routeSettings) {
  return MaterialPageRoute(
    settings: routeSettings,
    builder: (context) => Scaffold(
      body: Center(
        child: Text('404!'),
      ),
    ),
  );
},

加载应用程序后，它会按预期运行，并毫无例外地直接进入登录屏幕。如果您输入未知路线，我会看到 404 not found scaffold 。如果您打开一个新选项卡并粘贴完全相同的网址，即 http://localhost:5000/#/login 我得到：

Could not navigate to initial route.
The requested route name was: "/login"
There was no corresponding route in the app, and therefore the initial route specified will be ignored and "/" will be used instead.

这个问题是我试图通过另一个应用程序中的 webview 访问已知路由并传递 url 参数，并且总是遇到这个问题。有没有办法捕获这个事件，因为 onUnknownRoute 和 onGenerateRoute 都没有被调用并且导航恢复到“/”。

我的flutter doctor -v输出：
