Map<String, dynamic> toMap()

Implementation

Map<String, dynamic> toMap() {
  var map = <String, dynamic>{"type": type!.toValue(), "selector": selector};

  map.keys
      .where((key) =>
          map[key] == null ||
          (map[key] is List && (map[key] as List).isEmpty)) // filter keys
      .toList() // create a copy to avoid concurrent modifications
      .forEach(map.remove);

  return map;
}
