final StringManager str = StringManager.instance;

void main() async {

  StringManager(language: Intl.defaultLocale);

  await str.initialize();

  ///you must initialize the stringManager first

}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

      const MaterialApp(
        home: MyHomePage(),
      );
}

class MyHomePage extends StatefulWidget {


  const MyHomePage({
    Key? key,
  }) : super(key: key);

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  @override
  void dispose() {
    ///do not forget to close or save your strings
    str.save();
    str.close();
    super.dispose();

          children: <Widget>[
            Text(
              str.reg('You have pushed the button this many times'),

              ///str.reg(String text) registers the string in stringManger and returns it to be used
