Error: Unsupported operation: Platform._localeName

Question

我正在使用 dart.io 包并尝试使用 Platform.localeName 检测系统的当前位置，就像这样

WidgetsFlutterBinding.ensureInitialized();
String defaultSystemLocale = Platform.localeName;
print('$defaultSystemLocale');

但是当我运行 Chrome (Web) 中的应用程序时，出现此错误

Error: Unsupported operation: Platform._localeName
    at Object.throw_ [as throw] (http://localhost:62284/dart_sdk.js:5061:11)
    at Function._localeName (http://localhost:62284/dart_sdk.js:54692:17)
    at Function.localeName (http://localhost:62284/dart_sdk.js:54698:71)
    at Function.get localeName [as localeName] (http://localhost:62284/dart_sdk.js:54574:27)
    at main (http://localhost:62284/packages/testapp/main4.dart.lib.js:97:45)

知道为什么吗？

如果您从 dart:io 获取 Platform，它在网络上不受支持（改为 see this website). You can import it from universal_io。
