dart - Unhandled Exception: type 'List<dynamic>' is not a subtype of type 'List<Map<dynamic, dynamic>>' Flutter Firebase

Question

I am trying to get a list from firebase document and then set to another empty List of maps then add a map to this list of maps and pass it back to Firebase.

This is My method:

Future logFinalWorkout(user, finalWorkout) async{
 List<Map<dynamic, dynamic>> result = List<Map<dynamic, dynamic>>();
await users.document(user.uid).get().then((doc){
  result = doc.data['finalWorkouts'];
  result.addAll(finalWorkout);
});
return await users.document(user.uid).updateData({
  'finalWorkouts' : result,
});

}

finalWorkout parameter is of type Map<dynamic,dynamic> final workouts represents the list coming from Firebase. I keep getting the above error

Answer 1

Remove List<Map<dynamic, dynamic>> result and add List< dynamic> result instead of that. Give it a try.
