TIL it's actually easier than I thought to share a memory buffer between Isolates in Dart, and thus avoid the copy cost.
This punches a hole in the isolation but could also be very helpful for performance.
Most people won't need this but if you have a long-living chunk of data that is constantly being updated (common in some games), then this is fantastic news.
![void main() async {
const n = 1000;
final pointer = malloc.allocate<Int64>(n * Int64List.bytesPerElement);
final array = pointer.asTypedList(n, finalizer: malloc.nativeFree);
final random = Random();
for (var i = 0; i < n; i++) {
array[i] = random.nextInt(10);
}
print('Original array: $array');
final receivePort = ReceivePort();
final isolate = await Isolate.spawn(isolateEntry, [
receivePort.sendPort,
n,
pointer,
]);](https://files.mastodon.social/media_attachments/files/114/619/536/149/535/300/original/5669b61844e89d2f.png "void main() async {

Although #ManfredApp (my Mastodon client) is written in Flutter, I am working with #Kotlin in the backend for quite some time and like it better than #Dartlang. Having checked out the latest news from KotlinConf, I am now going to give Compose Multiplatform a try. The last time I checked, it did not have hot reload, which instantly put me off. However, hot reload for Compose is now in alpha, so let's see how it goes.
