whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String id,
    2. String orgId,
    3. String domainId,
    4. String? domainName,
    5. String? curriculumLevelId,
    6. String? teamId,
    7. String? userId,
    8. String assignedBy,
    9. DateTime assignedAt,
    10. DateTime? dueDate,
    )?
)

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 orgId,  String domainId,  String? domainName,  String? curriculumLevelId,  String? teamId,  String? userId,  String assignedBy,  DateTime assignedAt,  DateTime? dueDate)?  $default,) {final _that = this;
switch (_that) {
case _CurriculumAssignmentModel() when $default != null:
return $default(_that.id,_that.orgId,_that.domainId,_that.domainName,_that.curriculumLevelId,_that.teamId,_that.userId,_that.assignedBy,_that.assignedAt,_that.dueDate);case _:
  return null;

}
