You should define TextEditingController instance like below inside the widget class.

final textController1 = TextEditingController()
final textController2 = TextEditingController()
final textController3 = TextEditingController()

and set as value of controller. Do it for others too.

                TextFormField(
                  controller: textController1,
                  keyboardType: TextInputType.text,
                  decoration: const InputDecoration(
                    labelText: 'QuestionId ? ',
                  ),
                  validator: (value) {
                    if (value == null || value.isEmpty) {
                      return 'QustionId Required';
                    }
                    return null;
                  },
                  onSaved: (value) {
                    AddQuestionData['QuestionId'] = textController1.text.trim();
                  },
                ),
TextFormField(
controller: textController2,
...

Created 10 Controllers

  final textController1 = TextEditingController();
  final textController2 = TextEditingController();
  final textController3 = TextEditingController();
  final textController4 = TextEditingController();
  final textController5 = TextEditingController();
  final textController6 = TextEditingController();
  final textController7 = TextEditingController();
  final textController8 = TextEditingController();
  final textController9 = TextEditingController();
  final textController10 = TextEditingController();

doing this for all form fields

TextFormField(
                  controller: textController1,    // value of each TextController is different... in 2nd form field used different controller.
                  keyboardType: TextInputType.text,
                  decoration: const InputDecoration(
                    labelText: 'QuestionId ? ',
                  ),
                  validator: (value) {
                    if (value == null || value.isEmpty) {
                      return 'QustionId Required';
                    }
                    return null;
                  },
                  onSaved: (value) {
                    AddQuestionData['QuestionId'] = textController1.text.trim();    // same thing followed here also.
                  },
                ),

Thanks !

Declare as follows: final textController = TextEditingController();

And then use it in TextFormField: TextFormField( controller: textController, .. )
