maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(String? userId, @JsonKey.new(readValue: _PPBuyerHelper.readEmail) String? email, PPName? name, List<PPAddress>? addresses, @JsonKey.new(readValue: _PPBuyerHelper.readPhones) List<String>? phones,)?, { 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? userId,
          @JsonKey(readValue: _PPBuyerHelper.readEmail) String? email,
          PPName? name,
          List<PPAddress>? addresses,
          @JsonKey(readValue: _PPBuyerHelper.readPhones)
          List<String>? phones)?
      $default, {
  required TResult orElse(),
}) {
  final _that = this;
  switch (_that) {
    case _PPBuyer() when $default != null:
      return $default(_that.userId, _that.email, _that.name, _that.addresses,
          _that.phones);
    case _:
      return orElse();
  }
