The example https://pub.dev/packages/get/example only shows setting the locale from a string manually:
void main() {
runApp(GetMaterialApp(
...
locale: Locale('pt', 'BR'),
...
If I don't use "locale: Locale ('pt', 'BR')", then code like Text("title".tr) don't work. So, I need setup current locale to "locale" property, but how get current locale?
if BuildContext is available, we can get current locale this way
Locale myLocale = Localizations.localeOf(context);
according to the documentation https://flutter.dev/docs/development/accessibility-and-localization/internationalization
another option is to use the official intl library
import 'package:intl/intl.dart';
String locale = Intl.getCurrentLocale(); // returns language tag, such as en_US
To get Device Current Locale:
import 'package:get/get.dart';
return GetMaterialApp(
locale: Get.deviceLocale, //returns Locale('<language code>', '<country code>')
);
To get the App Current Locale:
import 'package:get/get.dart';
return GetMaterialApp(
locale: Get.locale, //returns Locale('<language code>', '<country code>')
);
The authors of the package added information about this in Readme (https://pub.dev/packages/get#internationalization):
To read the system locale, you could use window.locale.
import 'dart:ui' as ui;
return GetMaterialApp(
locale: ui.window.locale,
);
if u need device locale, u can use
return GetMaterialApp(
locale: Get.deviceLocale,
);
but u need current app locale u must be use
final locale = Get.locale;
You can use Get.locale read only property defined inside the LocalesIntl extension from package:get/get_utils/src/extensions/internacionalization.dart
final locale = Get.locale;
If you want current system locale, window.locale and add import 'dart:ui';
