whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String id,
    2. String name,
    3. String slug,
    4. String? description,
    5. String? iconName,
    6. int sortOrder,
    7. String? ownerId,
    8. String visibility,
    9. String? domainFamily,
    10. String? variant,
    )?
)

A variant of when that fallback to returning null

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return null;
}

Implementation

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? Function( String id,  String name,  String slug,  String? description,  String? iconName,  int sortOrder,  String? ownerId,  String visibility,  String? domainFamily,  String? variant)?  $default,) {final _that = this;
switch (_that) {
case _DomainEntity() when $default != null:
return $default(_that.id,_that.name,_that.slug,_that.description,_that.iconName,_that.sortOrder,_that.ownerId,_that.visibility,_that.domainFamily,_that.variant);case _:
  return null;

}
