How to get the current locale in Flutter using the GetX package?

Question

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?

Solution 1

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

Solution 2

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>')
);

Solution 3

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,
);

Solution 4

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';
