when<TResult extends Object?> method
- @optionalTypeArgs
- TResult $default(
- UModerationScheduleActionAction action,
- List<
String> subjects, - String createdBy,
- SchedulingConfig scheduling,
- ModTool? modTool,
- 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(@UModerationScheduleActionActionConverter() UModerationScheduleActionAction action, List<String> subjects, String createdBy, @SchedulingConfigConverter() SchedulingConfig scheduling, @ModToolConverter() ModTool? modTool, Map<String, dynamic>? $unknown) $default,) {final _that = this;
switch (_that) {
case _ModerationScheduleActionInput():
return $default(_that.action,_that.subjects,_that.createdBy,_that.scheduling,_that.modTool,_that.$unknown);case _:
throw StateError('Unexpected subclass');
}
