maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. int? plusOne,
    2. int? minusOne,
    3. int? confused,
    4. int? eyes,
    5. int? heart,
    6. int? hooray,
    7. int? laugh,
    8. int? rocket,
    9. int totalCount,
    10. ModelUri? url,
    )?, {
  2. 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();
}
