when<TResult extends Object?> method
- @optionalTypeArgs
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? totalReports, int? reportedCount, int? escalatedCount, int? appealedCount, int? subjectCount, int? pendingCount, int? processedCount, int? takendownCount, Map<String, dynamic>? $unknown) $default,) {final _that = this;
switch (_that) {
case _RecordsStats():
return $default(_that.$type,_that.totalReports,_that.reportedCount,_that.escalatedCount,_that.appealedCount,_that.subjectCount,_that.pendingCount,_that.processedCount,_that.takendownCount,_that.$unknown);case _:
throw StateError('Unexpected subclass');
}
