Stateless widget to Stateful widget convert Dart Flutter-CodePudding

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?

CodePudding user response：

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.

CodePudding user response：

Press ctrl . on vs-code to get convert option, and select option

While the data is nullable, you can remove required, if not needed.


class StocksDetailScreen extends StatefulWidget {
  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,
    this.sondeger,
    this.hacim,
    this.mindeger,
    required this.maxdeger,
    this.zaman,
    this.hisseismi,
    this.hissekodu,
  }) : super(key: key);

  @override
  State<StocksDetailScreen> createState() => _StocksDetailScreenState();
}

class _StocksDetailScreenState extends State<StocksDetailScreen> {
  @override
  Widget build(BuildContext context) {
    return Container();
  }
}
