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

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     
);

资源文件呢

Adventure · Answer 9 · Thu Nov 07 2019 09:13:17 GMT+0800 (China Standard Time)

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 · Answer 10 · Thu Nov 07 2019 10:19:12 GMT+0800 (China Standard Time)

错误信息很清楚啊！parameters[xxx] 是null，无法取值

Adventure · Answer 11 · Thu Nov 07 2019 10:21:04 GMT+0800 (China Standard Time)

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，。

Adventure · Answer 12 · Thu Nov 07 2019 10:21:29 GMT+0800 (China Standard Time)

之前是这样的这样路由是可以取值的

Sky24n · Answer 13 · Thu Nov 07 2019 10:32:02 GMT+0800 (China Standard Time)

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);
}

有调用的这边然后方法也进了

Adventure · Answer 15 · Thu Nov 07 2019 10:34:36 GMT+0800 (China Standard Time)

是因为顺序的问题？？？

Adventure · Answer 16 · Thu Nov 07 2019 10:36:54 GMT+0800 (China Standard Time)

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 · Answer 17 · Thu Nov 07 2019 10:43:05 GMT+0800 (China Standard Time)

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())；
}

Adventure · Answer 18 · Thu Nov 07 2019 10:52:29 GMT+0800 (China Standard Time)

好的我试试谢谢老哥的解答
