whenOrNull<TResult extends Object?> method
- @optionalTypeArgs
- TResult? $default(
- int? rand,
- XrayInt32Range? randRange,
- String? capture,
- String? type,
- String? reuse,
- CustomTransform? transform,
- Object? packet,
A variant of when that fallback to returning null
It is equivalent to doing:
switch (sealedClass) {
case Subclass(:final field):
return ...;
case _:
return null;
}
