CustomParameterCodec class final

annotation to define a custom parameter decoder/encoder this is useful when the is encoded/decoded in a non-standard way like base64Url this must be used as an annotation on a field

String fromBase64(String value) {
  return const Utf8Decoder()
    .convert(base64Url.decode(base64Url.normalize(value)));
}
String toBase64(String value) {
  return base64Url.encode(const Utf8Encoder().convert(value));
}
@TypedGoRoute<JsonRoute>(path: 'json')
class JsonRoute extends GoRouteData with _$EncodedRoute {
  @CustomParameterCodec(
    encode: toBase64,
    decode: fromBase64,
  )
  final String data;
  JsonRoute(this.data);
}
