In the lib folder of our project, let’s add a new file, called settings_screen.dart.

String _listName = ''; 
int _calories = 0; 
bool _showFileSize = false; 
final double fontSize = 22.0;
final _listNameController = TextEditingController(); 
final _caloriesController = TextEditingController(); 
@override 
  void initState() { 
    super.initState(); 
    _loadSettings(); 
  } 
@override 
void dispose() { 
    _listNameController.dispose(); 
    _caloriesController.dispose(); 
    super.dispose(); 
  }
