supportedLocales: CustomLocalizations.supportedLocales,//设置支持本地化语言集合这句话更改成 supportedLocales: [
const Locale('zh', 'CH'),
const Locale('en', 'US'),
], 这样APP 可以启动但是text取不到值

Sky24n · 2019-11-06T09:53:57Z

StatelessWidget 有initState这个方法吗？

MaterialApp(  
   home: MyHomePage(),  
   localizationsDelegates: [  
   GlobalMaterialLocalizations.delegate,  
   GlobalWidgetsLocalizations.delegate,  
   CustomLocalizations.delegate //设置本地化代理     
   ],  
   supportedLocales: CustomLocalizations.supportedLocales,//设置支持本地化语言集合     
);

改了但是还是这个问题

Sky24n · 2019-11-06T10:59:29Z

现在具体是什么问题？有没有截图之类的

Sky24n · 2019-11-06T14:34:00Z

资源文件呢

Gyueqi · 2019-11-07T01:13:17Z

请问为什么MAIN 突然报错之前都是好的现在加载H5 报错String 不是一个组件

Sky24n · 2019-11-07T02:19:12Z

错误信息很清楚啊！parameters[xxx] 是null，无法取值

Gyueqi · 2019-11-07T02:21:04Z

我没有改变main 的时候是可以取值的但是加了国际化然后变成StatefulWidget 后就取值不到了，。

Gyueqi · 2019-11-07T02:21:29Z

之前是这样的这样路由是可以取值的

Sky24n · 2019-11-07T02:32:02Z

大哥，下次好好检查下代码！

class RiverAppState extends State {
Locale _locale;
/// 这个方法都没有运行！！！
RiverApp() {
final router = Router();//放到 initState
Routers.configureRoutes(router);//initState
Application.router = router;//initState
}

改

@override
void initState() {
super.initState();
final router = Router();
Routers.configureRoutes(router);
Application.router = router;
setLocalizedValues(localizedValues);
}

Gyueqi · 2019-11-07T02:34:07Z

有调用的这边然后方法也进了

Gyueqi · 2019-11-07T02:34:36Z

是因为顺序的问题？？？

Gyueqi · 2019-11-07T02:36:54Z

按照老哥你这边的没用方法调用直接写进去也一样的这个我调试过的老哥

Sky24n · 2019-11-07T02:43:05Z

最后这样试试吧！再不行我也没有办法了！

void main()  {
final router = Router();
Routers.configureRoutes(router);
Application.router = router;
runApp(RiverApp())；
}

Gyueqi · 2019-11-07T02:52:29Z

好的我试试谢谢老哥的解答
