whenOrNull<TResult extends Object?> method
- @optionalTypeArgs
- TResult? $default(
- String? packets,
- XrayInt32Range? length,
- XrayInt32Range? delay,
- XrayInt32Range? maxSplit,
A variant of when that fallback to returning null
It is equivalent to doing:
switch (sealedClass) {
case Subclass(:final field):
return ...;
case _:
return null;
}
