Discussion on Requirements and Solutions for Unified Monitoring of Attribute Value Changes

[HCareLou]

Overview

In actual projects, there is often a requirement to record the old and new values of an attribute when its value changes (e.g., monitoring personnel changing parameters in the industrial field). In CommunityToolkit.MVVM, each property has its own OnXXXChanged(oldValue, newValue) method. However, this means I need to write n such functions to achieve the above functionality, which is not ideal. Is it possible to add a callback OnPropertyValueChanged(propertyName,oldValue, newValue)?
