transform method

dynamic transform(dynamic value, { String? fieldKey, })

Transforms a field value using the appropriate transformer registered for its type.

Parameters:

• value The field value to be transformed.

Returns: The transformed value, or the original value if no transformer is registered for its type.

Implementation

dynamic transform(dynamic value, {String? fieldKey}) {
  // Priority: field key transformer → type transformer
  final keyTransformer = fieldKey != null ? factoriesByKey[fieldKey] : null;
  final typeTransformer = factoriesByType[value.runtimeType];

  final transformer = keyTransformer ?? typeTransformer;

  // If no transformer is found, check if there is a transformer for the base type
  if (transformer == null && value is Iterable) {
    // Handle cases where the runtime type might be a collection type like Set or List
    if (value is Set) {
      return _transformCollection<Set>(value);
    } else if (value is List) {
      return _transformCollection<List>(value);
    }
  }
  return transformer?.transform(value);
