Flutter Scaffold(appBar: AppBar()) not working 'const' error

 void main() {

  runApp(
    const MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('I am Rich'),
        ),
      ),
    ),
  );
}

MaterialApp önünde bulunan const siliniz

void main() {
  runApp(MaterialApp(
    home: Scaffold(
      appBar: AppBar(
        backgroundColor: Colors.indigo,
        title: Text('Mehmet BALIK'),
      ),
    ),
  ));
}
