toMap method
This method returns a Map<String,String> object of the current state of the question cards. This format is useful for writing to a database eg Firestore.
Implementation
Map<String, dynamic> toMap() {
Map<String, dynamic> temp = new Map<String, dynamic>();
_expanded.forEach((element) {
String? answer = (!(element.keys.toList()[0] is NestedQuestion ||
element.keys.toList()[0] is PolarQuestion))
? element.keys.toList()[0].answer.text
: element[element.keys.toList()[0]];
temp[element.keys.toList()[0].toString()] = answer;
});
return temp;
}
