With reference #79 issue, I am getting type error

[Vpdwivedi]

Describe the bug Getting the error '_Map<dynamic, dynamic>' is not a subtype of type 'Map<String, Object?>?' however I am storing the survey response data to HiveBox and then sending the same response data to answer. If I add a survey and edit the same response works fine but Error coms when I restart the application and then going to the edit survey screen.

To Reproduce SurveyJs json

{
 "title": "Survey Form for Commune",
 "description": "Survey for commune level users",
 "logoFit": "cover",
 "logoPosition": "right",
 "pages": [
  {
   "name": "Page1",

Not familiar with HiveBox, but I believe that you can try to store as string into HiveBox and then deserialize it as Map<String, Object?>

s.SurveyWidget(
      survey: survey!,
      onChange: (v) {
         final String s = json.encode(v);
         // put s into hivebox
      }

after your application restart

FutureBuilder(
  future:  //get s from hivebox
  builder :(){
      s.SurveyWidget(
        survey: survey!,
        answer: json.decode(snapshot.data)
   }
)
