maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(String platform, Sub2ApiDecimal todayActualCost, Sub2ApiDecimal totalActualCost)?, { 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 platform,
    Sub2ApiDecimal todayActualCost,
    Sub2ApiDecimal totalActualCost,
  )?
  $default, {
  required TResult orElse(),
}) {
  final _that = this;
  switch (_that) {
    case _Sub2ApiAdminPlatformUsage() when $default != null:
      return $default(
        _that.platform,
        _that.todayActualCost,
        _that.totalActualCost,
      );
    case _:
      return orElse();
  }
}
