How to only listen for property changes

[eefan000]

I want to monitor property changes and then play animations or special effects

I know there is a 'BindingProperty', but it must have a parameter and it will generate extra code.
Perhaps we can consider adding a 'ListenerPropertyChanged'?

There are partial methods generated inside your observable classes so you can implement custom logic upon either or both value changing and value changed events.

public partial class MyModel : IObservableObject
{
    [ObservableProperty] public int IntValue { get => Get_IntValue(); set => Set_IntValue(value); }

    partial void OnIntValueChanging(int oldValue, int newValue)
    {
        // run before newValue is assigned to the backing field _intValue
    }

    partial void OnIntValueChanged(int oldValue, int newValue)
    {
        // run after newValue is assigned to the backing field _intValue
    }
}

I have an ACAnimatorPlayerBinder and I hope to provide a feature to play animations when any property changes

Okay. Got it.
