encoding property

@override String? get encoding

encode algorithms Gets the encoding algorithm name (e.g., 'base64').

Implementation

@override
String? get encoding {
  var uri = dataUri;
  if (uri == null) {
    assert(false, 'data uri error');
    return null;
  } else if (uri.isBase64) {
    return EncodeAlgorithms.BASE_64;
  }
  // plaintext
  return '';
}
