Can onStateUpdate include the prev state?

[kchro3]

I have a case where I'd like to handle specific types of updates, so if the state is an object, i want to handle a change to a field.

However, I think I need access to the previous state in order to see if the field had changed.

Proposed:

  onStateUpdate(state: State | undefined, prevState: State | undefined, source: Connection | "server") {
    if (state?.field !== prevState?.state) {
      // do something
    }
  }

yeah we could do this. might have to put prevState as the last arg so it's not a breaking change. wanna make a PR?

@kchro3 is it something that you still need?
