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? orgId,
    10. bool isStarter,
    11. String? domainFamily,
    12. 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? orgId,  bool isStarter,  String? domainFamily,  String? variant)?  $default,) {final _that = this;
switch (_that) {
case _DomainModel() when $default != null:
return $default(_that.id,_that.name,_that.slug,_that.description,_that.iconName,_that.sortOrder,_that.ownerId,_that.visibility,_that.orgId,_that.isStarter,_that.domainFamily,_that.variant);case _:
  return null;
