UserLocations.fromJSON constructor

Implementation

factory UserLocations.fromJSON(json) {
  // Convertir los valores de totalUsers y totalLocations a int,
  // en caso de que vengan como String.
  int totalUsers = int.tryParse(json['totalUsers'].toString()) ?? 0;
  int totalLocations = int.tryParse(json['totalLocations'].toString()) ?? 0;

  // Clonar el mapa para separar los campos de conteo de ubicaciones.
  final Map<String, dynamic> countsJson = Map<String, dynamic>.from(json);
  countsJson.remove('totalUsers');
  countsJson.remove('totalLocations');

  // Convertir cada valor a int.
  Map<String, int> locationCounts = countsJson.map((key, value) =>
      MapEntry(key, int.tryParse(value.toString()) ?? 0));

  return UserLocations(
    totalUsers: totalUsers,
    totalLocations: totalLocations,
    locationCounts: locationCounts,
  );
