Question

I did a todo list, I want to send data home screen but I cannot.
I want to get data from page 2 with to do list app and create object on page 1 and add it to the list, but I can't send it with constructor.
class IlkEkran extends StatefulWidget {
String? works;
toDolist("Limon ", DateTime.now())
];
toDolist selectedIndex = toDolist.testerobject();
String? works;
_IlkEkranState({String? works}) { error is here
this.works = works;
}
#override
Widget build(BuildContext context) {
return Container(
child: Column(children: [
Flexible(
child: ListView.builder(
itemCount: listem.length,
itemBuilder: (context, index) {
return Card(
margin: EdgeInsets.all(5),
elevation: 20,
child: ListTile(
title: Text(listem[index].yapilacaklar),
subtitle: Text(listem[index].tarih.toString()),
leading: CircleAvatar(child: Icon(Icons.shopping_basket)),
trailing: Wrap(
spacing: 5,
children: [
IconButton(
onPressed: () {
selectedIndex = listem[index];
setState(() {
listem.remove(selectedIndex);
});
},
icon: Icon(Icons.delete)),
IconButton(
onPressed: () {
setState(() {
toDolist newWork =
toDolist(works!, DateTime.now());
listem.add(newWork);
});
},
icon: Icon(Icons.notification_important)),
],
),
),
);
}),
),
]),
);
}
}
