Methods

Method	Job
currentLanguage	returns current Language
locale	returns current Locale
init()	initialize things, before runApp()
translate(word)	returns word translation
setNewLanguage('en')	switch to another language
locals()	returns current Locales

How To Use

1. add localize_and_translate: ^<latest> to pubspec.yaml dependencies
2. run flutter pub get into root dir of the app
3. add import 'package:flutter_localizations/flutter_localizations.dart'; to use GlobalMaterialLocalizations.delegate
4. add import 'package:localize_and_translate/localize_and_translate.dart'; to use plugin 😁
5. wrap app entry into LocalizedApp(), and make sure you define it's child into different place "NOT INSIDE"

  runApp(
    LocalizedApp(
      child: MyApp(),
    ),
  );

6. convert your main() method to async, we will need next

Future<void> main() async {
  runApp(
    LocalizedApp(
      child: MyApp(),
    ),
  );
}

7. add WidgetsFlutterBinding.ensureInitialized(); at very first of main()
8. inside main() define your languages

LIST_OF_LANGS = ['ar', 'en'];

9. add .json translation files as assets

• For example : 'assets/langs/ar.json'| `'assets/langs/en.json'
• structure should look like

{
  "appTitle" : "Example",
  "buttonName" : "التحول للعربية",
}

{
  "appTitle" : "تجربة",
  "buttonName" : "English",
}

• define them as assets into pubspec.yaml

flutter:
  assets:
    - assets/langs/en.json
    - assets/langs/ar.json

• run flutter pub get
• into main() define your root directory

LANGS_DIR = 'assets/langs/';

10. intialize plugin await translator.init();

• so now your main() should look like this

Future<void> main() async {
  // if your flutter > 1.7.8 :  ensure flutter activated
  WidgetsFlutterBinding.ensureInitialized();

  LIST_OF_LANGS = ['ar', 'en']; // define languages
  LANGS_DIR = 'assets/langs/'; // define directory
  await translator.init(); // intialize

  runApp(
    LocalizedApp(
      child: MyApp(),
    ),
  );
}

11. define your LocalizedApp() child as MaterialApp() like this

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Home(), // re Route
      localizationsDelegates: [
        GlobalMaterialLocalizations.delegate,
        GlobalWidgetsLocalizations.delegate,
      ],
      locale: translator.locale,
      supportedLocales: translator.locals(),
    );
  }
}

12. enjoy like next example

• we use translate(word)
• setNewLanguage(languageCode) : and it's parameters

class Home extends StatefulWidget {
  @override
  _HomeState createState() => _HomeState();
}

class _HomeState extends State<Home> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      drawer: Drawer(),
      appBar: AppBar(
        title: Text(translator.translate('appTitle')),
        // centerTitle: true,
      ),
      body: Container(
        width: double.infinity,
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.center,
          children: <Widget>[
            SizedBox(height: 50),
            Text(
              translator.translate('textArea'),
              style: TextStyle(fontSize: 35),
            ),
            SizedBox(height: 150),
            OutlineButton(
              onPressed: () {
                translator.setNewLanguage(
                  context,
                  newLanguage: translator.currentLanguage == 'ar' ? 'en' : 'ar',
                  remember: true,
                  restart: true,
                );
              },
              child: Text(translator.translate('buttonTitle')),
            ),
          ],
        ),
      ),
    );
  }
}
