      ),


      home: MyHomePage(),


    );


  }


}


 


class MyHomePage extends StatefulWidget {


  @override


  _MyHomePageState createState() => _MyHomePageState();


}


 


class _MyHomePageState extends State<MyHomePage> {


  @override


  Widget build(BuildContext context) {


    return Scaffold(


      appBar: AppBar(


        title: Text('Flutter Google Sign-In'),


      ),


      body: Center(


        child: ElevatedButton(
