maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(String? email, int? level, String id, String? flow, String? seed, String? encryption, VLessReverseConfig? reverse, int? testpre, List<int>? testseed,)?, { required TResult orElse(), })

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  TResult Function(
          String? email,
          int? level,
          String id,
          String? flow,
          String? seed,
          String? encryption,
          VLessReverseConfig? reverse,
          int? testpre,
          List<int>? testseed)?
      $default, {
  required TResult orElse(),
}) {
  final _that = this;
  switch (_that) {
    case _VLessUser() when $default != null:
      return $default(
          _that.email,
          _that.level,
          _that.id,

    case _:
      return orElse();
  }
