Stateless widget to Stateful widget convert Dart Flutter

This is my code :

class StocksDetailScreen extends StatelessWidget {

  final String degisimoran;
  final String? sondeger;
  final String? hacim;
  final String? mindeger;
  final String maxdeger;
  final String? zaman;
  final String? hisseismi;
  final String? hissekodu;



  const StocksDetailScreen({
Key? key,
required this.degisimoran,
required this.sondeger,
required this.hacim,
required this.mindeger,
required this.maxdeger,
required this.zaman,
required this.hisseismi,
required this.hissekodu,


  }) : super(key: key);

  Widget build(BuildContext context) {

I need to convert it to stateful widget because I will use setstate. but when I implement my const (which I call from API) in stateful I get null safety errors. what is the best way to do this?

Solution

  • Move your cursor at statelessWidget word and press Alt + Enter (android studio) and you will get an option to convert statefulWidgets. You can convert easily.
