fromJson static method

CharacterStatsSchema? fromJson(dynamic value)

Returns a new CharacterStatsSchema instance and imports its values from value if it's a Map, null otherwise.

Implementation

// ignore: prefer_constructors_over_static_methods
static CharacterStatsSchema? fromJson(dynamic value) {
  if (value is Map) {
    final json = value.cast<String, dynamic>();

    // Ensure that the map contains the required keys.
    // Note 1: the values aren't checked for validity beyond being non-null.
    // Note 2: this code is stripped in release mode!
    assert(() {
      return true;
    }());

    return CharacterStatsSchema(
      monstersKilled:
          mapCastOfType<String, int>(json, r'monsters_killed') ?? const {},
      resourcesGathered:
          mapCastOfType<String, int>(json, r'resources_gathered') ?? const {},
      actionCounts:
          mapCastOfType<String, int>(json, r'action_counts') ?? const {},
      deaths: mapValueOfType<int>(json, r'deaths') ?? 0,
    );
  }
  return null;
