Question

I am trying to fetch data from my create and showing those data into my update page data are coming. I am able to update from normal textformfield, but am not able to edit data from my drop down table. Please anyone give suggestion that where am doing mistake.
class UpdateEdic extends StatefulWidget {
final String docId;
const UpdateEdic({
Key? key,
required this.docId,
}) : super(key: key);
#override
_UpdateEdicState createState() => _UpdateEdicState();
}
class _UpdateEdicState extends State<UpdateEdic> {
final _formKey = GlobalKey<FormState>();
CollectionReference devtradecalls =
FirebaseFirestore.instance.collection('dev-trade-calls');
List<String> tslList = ['T', 'F'];
String imageUrl = "";
List<String> archivedList = ['T', 'F'];
List<String> targetAchivedList = ['T', 'F'];
DateTime tgtachtime = DateTime.now();
DateTime calltime = DateTime.now();
List tools = [];
List indicators = [];
String imageFilePath = "";
File? _imageFile;
final _picker = ImagePicker();
final format = DateFormat("HH:mm dd-MM-yyyy");
Future<void> updateEdicData(id, tsl, pattern, indicators, tools, img, notes,
targetAchieved, targetAchievedTime, archived, callTime) {
return devtradecalls
.doc(id)
.update({
'tsl': tsl,

'tools': tools,
'img': img,
'notes': notes,

})
.then((value) => Navigator.pop(context))
.catchError((error) => print('Failed to update: $error'));
}
