Add Overridable Method on BlazorStateComponent That Will Be Invoked on Dispose about blazor-state HOT 4 CLOSED

Thanks for using blazor-state and take the time to give your input.
I will be updating to 3.1 this weekend. So if this is something we determine beneficial it could make it in.

Can you give me an example use case?
I am thinking you probably have your own base component in your code that you could implement Dispose on?

The BlazorStateComponent is ensuring it clears the stuff it responsible for.

In my case, I needed to update a state when a component is disposed. My first attempts is to hide the BlazorStateComponent Dispose method in my component, but that did not work.

Then I figure I can create my own base component, but seems like I would need to manage the component state change manually? Since if I were to create a GetState method, the Subscriptions.Add only accept component of type BlazorStateComponent .

    protected T GetState<T>()
    {
      Type stateType = typeof(T);
      Subscriptions.Add(stateType, this);
      return Store.GetState<T>();
    }

I guess changing Subscriptions.Add method to accept IBlazorStateComponent interface instead can be an option. Or maybe my assumption of how the component state changes are handled is wrong?

Also, thank you for creating such an awesome library. 👍

Have your base component inherit from BlazorStateComponent. Then you can dispose your stuff and it will manage the subscritpions.

Aha! I see. So seems like I missed a small but important detail here.

    public class MyComponentBase1 : BlazorStateComponent
    {
        public new void Dispose()
        {
            throw new Exception("WILL NOT BE CALLED");
            base.Dispose();
        }
    }

    public class MyComponentBase2 : BlazorStateComponent, IDisposable
    {
        public new void Dispose()
        {
            throw new Exception("WILL BE CALLED");
            base.Dispose();
        }
    }

Previously, I wrote my base component like the MyComponentBase1 in the snippet and the dispose does not work as expected. After I changed it like the MyComponentBase2, then It works.

Thank you! I will now close this issue.
