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? email, int? level, String id, String? flow, String? seed, String? encryption, VLessReverseConfig? reverse, int? testpre, List<int>? testseed) $default,) {final _that = this;
switch (_that) {
case _VLessUser():
return $default(_that.email,_that.level,_that.id,_that.flow,_that.seed,_that.encryption,_that.reverse,_that.testpre,_that.testseed);case _:
throw StateError('Unexpected subclass');
}
