How to take int from json and parse it as bool in dart?

Question

I have my model as follows:

class Abc extends Model {
  int playful;

  Abc({this.playful}) : super(id);

  Abc.fromJson(Map<String, dynamic> json) : this(playful: json['playful']);

  Map<String, dynamic> toJson() {
    final Map<String, dynamic> data = new Map<String, dynamic>();
    data['playful'] = this.playful;
    return data;
  }
}

I am getting integer value playful (it is either 1 or 0) from json but I want to use it as a boolean in my app (receive as bool in app but send as int in database). How do I achieve it?

Solution 1

Try this,

class Abc extends Model {
  bool playful;

  Abc({this.playful}) : super(id);

  Abc.fromJson(Map<String, dynamic> json) : this(playful: json['playful'] == 1);

  Map<String, dynamic> toJson() {
    final data = <String, dynamic>{};
    data['playful'] = this.playful ? 1 : 0;
    return data;
  }
}

Solution 2

As far as I know, Dart doesn't have any function or method for parsing booleans. So I would create a private function in this class which would return boolean for given integer.

bool parseBool(int integer) {
  return integer == 1;
}
