Flutter Modular 重定向到 404 页面

Question

我使用 flutter_modular 进行 flutter web 导航。

import 'package:flutter_modular/flutter_modular.dart';

 class AppModule extends Module {
   @override
   final List<Bind> binds = [];

   @override
   final List<ModularRoute> routes = [
       ChildRoute('/', child: (_, __) => HomeScreen()),
       ChildRoute('/signin', child: (_, __) => SignInPage()),
       ChildRoute('/login', child: (_, __) => LogInPage()),
       ChildRoute('/404', child: (_, __) => Custome404()),
  ];
 }

如果不幸的是用户键入了 URL，例如 example.com/gfhgfhb/。 flutter 模块化插件显示错误 Error: RouteNotFoundException: Route (/rferwg) not found。现在谁可以在代码中设置默认 404 页面？

Answer 1

您在某处使用 MaterialApp、CupertinoApp 或 WidgetsApp 吗？如果是这样，您可以使用 onUnknownRoute 属性:

onUnknownRoute: (settings) {
  return MaterialPageRoute(builder: (_) => PageNotFound());
},

Answer 2

你可以使用 WildcardRoute :

WildcardRoute(child: (context, args) => NotFoundPage()),

根据其 documentation :

Have only one WildcardRoute per module and, if possible, let it be the last element.
