flutter - 更改支持的语言环境

Question

我通过此补丁根据相关的this line更改documentation:

           return MaterialApp(

             // ...

             initialRoute: initialRoute,
-            supportedLocales: GalleryLocalizations.supportedLocales,
+            supportedLocales: [
+              const Locale('en'),
+              const Locale('he'),
+            ],
             locale: GalleryOptions.of(context).locale,
             localeResolutionCallback: (locale, supportedLocales) {
               deviceLocale = locale;
               return locale;
             },

// ...

但是设置页面上的语言环境选项未修改。知道为什么吗？

设置页面支持的语言环境位于lib/pages/settings.dart文件中，可以通过使用此修补程序修改this line来进行限制:

-    var supportedLocales =
-        List<Locale>.from(GalleryLocalizations.supportedLocales);
+    var supportedLocales = [
+      const Locale('en'),
+      const Locale('he'),
+    ];
     supportedLocales.removeWhere((locale) => locale == deviceLocale);
