"previousValue" getter does not on signal

[tdomarkas]

Code provided on https://github.com/rodydavis/signals.dart/blob/main/website/src/content/docs/dart/core/signal.md#previousvalue doesn't work as "previousValue" does not exist.

Is this just outdated documentation issue?

[rodydavis]

It should still be the case. It should only be removed for value signal.

I'll double check on the code and documentation

I can confirm on 4.5.1 that previousValue doesn't exist in the above case as per the documentation.

final counter = signal(0);

effect(() {
    print('Current value: ${counter.value}');
    print('Previous value: ${counter.previousValue}');
});

counter.value = 1;

---

The getter 'previousValue' isn't defined for the type 'Signal<int>'.
Try importing the library that defines 'previousValue', correcting the name to the name of an existing getter, or defining a getter or field named 'previousValue'.

Ah it is because I moved it to TrackedReadonlySignal and Signal does not expose it.

Just an interface issue, will fix it!

[rodydavis]

Will be fixed on the next release!

Added an error via mixin for the value signals on the latest beta
