maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(String date, int userId, String email, String username, int requests, int tokens, Sub2ApiDecimal cost, Sub2ApiDecimal actualCost,)?, { 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 date,
    int userId,
    String email,
    String username,
    int requests,
    int tokens,
    Sub2ApiDecimal cost,
    Sub2ApiDecimal actualCost,
  )?
  $default, {
  required TResult orElse(),
}) {
  final _that = this;
  switch (_that) {
    case _Sub2ApiAdminUserUsageTrendPoint() when $default != null:
      return $default(
        _that.date,
        _that.userId,
        _that.email,
        _that.username,
        _that.requests,
        _that.tokens,
        _that.cost,
        _that.actualCost,
      );
    case _:
      return orElse();
  }
