Is there a hashing algorithm that produces identical results in both Dart and TypeScript?

I am looking to create a unique identifier for my chat application. (Chat between my Flutter app and Angular web)

Below is the code snippet written in Dart...

   String peerId = widget.peerid; //string ID value
    String currentUserId = widget.currentId; //string ID value

    if (currentUserId.hashCode <= peerId.hashCode) {
      ChatId = '$currentUserId-$peerId';
    } else {
      ChatId = '$peerId-$currentUserId';
    }
    print(ChatId);

I have successfully generated a chatID using this code. Now, I want to achieve the same functionality for the chat room on my web app. How can I generate a similar chatID like the one created in Dart?
