maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(@JsonKey.new(name: 'method') String? cipher, String password, int? level, String? email, XrayAddress? address, int? port,)?, { 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(@JsonKey(name: 'method') String? cipher, String password,
          int? level, String? email, XrayAddress? address, int? port)?
      $default, {
  required TResult orElse(),
}) {
  final _that = this;
  switch (_that) {
    case _ShadowsocksUserConfig() when $default != null:
      return $default(_that.cipher, _that.password, _that.level, _that.email,
          _that.address, _that.port);
    case _:
      return orElse();
  }
}
