maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(DateTime? startDate, DateTime? endDate, String? timezone, int? limit,)?, { 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(
    DateTime? startDate,
    DateTime? endDate,
    String? timezone,
    int? limit,
  )?
  $default, {
  required TResult orElse(),
}) {
  final _that = this;
  switch (_that) {
    case _Sub2ApiAdminUserSpendingRankingQuery() when $default != null:
      return $default(
        _that.startDate,
        _that.endDate,
        _that.timezone,
        _that.limit,
      );
    case _:
      return orElse();
  }
}
