The translation comes down to adding a ".tr" to the end of your String, and changing the locale with Get.changeLocale.
follow the example:

import 'package:flutter/material.dart';
import 'package:get/get.dart';

void main() {
  runApp(GetMaterialApp(
    initialRoute: '/home',
    translations: MyTranslations(),
    locale: Locale('pt', 'BR'), // insert initial locale
    getPages: [
      GetPage(name: '/home', page: () => First()),
    ],
  ));
}

class First extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("title".trArgs(['John'])), // use String.tr or String.trArgs
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            RaisedButton(
              child: Text('Change locale to English'),
              onPressed: () {
                Get.updateLocale(Locale('en', 'UK')); // update locale
              },
            ),
          ],
        ),
      ),
    );
  }
}

class MyTranslations extends Translations {
  @override
  Map<String, Map<String, String>> get keys => {
        'en': {
          'title': 'Hello World %s',
        },
        'en_US': {
          'title': 'Hello World from US',
        },
        'pt': {
          'title': 'Olá de Portugal',
        },
        'pt_BR': {
          'title': 'Olá do Brasil',
        },
      };
}
