step 1
安装Android Studio 插件 Flutter_i18n （当前版本是0.2）
step 2
安装完成之后，重启 Android Studio，flutter项目下面会出现res/values文件夹
step 3
点击同步按钮，会自动生成lib/generated/i18n.dart
step 4
4.编辑main.dart, 由于lib/generated/i18n.dart文件有bug，所以localizationsDelegates, localeResolutionCallback部分代码需要重写
class MyApp extends StatelessWidget {
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
theme: ThemeData(
primarySwatch: Colors.red,
),
localizationsDelegates: [
S.delegate,
GlobalMaterialLocalizations.delegate,
GlobalWidgetsLocalizations.delegate,
],
supportedLocales: <Locale>[
Locale("en", ""),
Locale("zh", ""),
Locale("fr", ""),
Locale("de", ""),
],
localeResolutionCallback: (Locale locale, Iterable<Locale> supported) {
bool isSupported(Locale locale) {
if (locale == null) return false;
if (supported.contains(locale)) {
return true;
} else {
for (Locale supportedLocale in supported) {
if (supportedLocale.countryCode == null || supportedLocale.countryCode.isEmpty)
if (supportedLocale.languageCode == locale.languageCode) return true;
}
return false;
}
}
if (!isSupported(locale))
return supported.first;
final Locale languageLocale = Locale(locale.languageCode, "");
if (supported.contains(locale)) return locale;
else if (supported.contains(languageLocale)) return languageLocale;
else return supported.first;
},
home: MyHomePage(),
);
}
}
step 5
重启应用
