when<TResult extends Object?> method

TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. int id,
    3. @UModEventViewEventConverter() UModEventViewEvent event,

    9. String? subjectHandle,
    10. @ModToolConverter() ModTool? modTool,
    11. Map<String, dynamic>? $unknown,
    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( String $type,  int id, @UModEventViewEventConverter()  UModEventViewEvent event, @UModEventViewSubjectConverter()  UModEventViewSubject subject,  List<String> subjectBlobCids,  String createdBy,  DateTime createdAt,  String? creatorHandle,  String? subjectHandle, @ModToolConverter()  ModTool? modTool,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _ModEventView():
return $default(_that.$type,_that.id,_that.event,_that.subject,_that.subjectBlobCids,_that.createdBy,_that.createdAt,_that.creatorHandle,_that.subjectHandle,_that.modTool,_that.$unknown);case _:
  throw StateError('Unexpected subclass');
