Blazor Hybrid MAUI app - ReducerMethods not being called

[lwinch2006]

I'm testing Fluxor with Blazor Hybrid app. And it looks like methods decorated with [ReducerMethod] attribute is not being called.

Setup in MauiProgram.cs

        builder.Services
            .AddFluxor(options =>
            {
                options.WithLifetime(StoreLifetime.Singleton);
                options.ScanAssemblies(typeof(AppStore).Assembly);
            })
            .AddScoped(sp => new HttpClient { BaseAddress = new Uri("https://localhost") })
            .AddBlazorWebViewDeveloperTools()
            .AddMauiBlazorWebView();

Defined action

public record ClearUserReadAction
{
    public ClearUserReadAction()
    {
        Console.WriteLine("ACTION CREATED");
    }
}

Defined reducer

    [ReducerMethod(typeof(ClearUserReadAction))]
    public static AppStore ReduceClearUserReadAction(AppStore appStore)
    {
        Console.WriteLine("ACTION PROCESSED");

        return appStore with {IsLoading = true, UserRead = null, Elapsed = TimeSpan.Zero, ErrorMessage = null };
    }

Calling from Razor component

    [Inject] private IState<AppStore> State { get; set; } = default!;

    [Inject] private Fluxor.IDispatcher Dispatcher { get; set; } = default!;

    private AppStore AppStore => State.Value;

    private async Task Refresh()
    {
        Console.WriteLine("BEFORE ACTION CALLED");

        Dispatcher.Dispatch(new ClearUserReadAction());

    }

So console prints out BEFORE ACTION CALLED AND ACTION CREATED, but not ACTION PROCESSED. So I'm concluding that ReducerMethod not being called.

In usual Blazor WASM app all works OK

Can you provide me with a repro?

[lwinch2006]

Hello. I have created a sample MAUI + Blazor + Fluxor project. It is just a sample app generated from Microsoft template with Counter page. With Fluxor I created sample IncrementCountAction that should lead to calling ReduceIncrementCountAction, but it is not. Incrementing count with local function works normally. Tested for Mac Catalyst, iOS and Android platforms

Have you added a <StoreInitializer> component somewhere, such as Main.razor?

[lwinch2006]

Oh my bad 😰, nope, the most embarrassing that I added it in WASM app but not added in MAUI app. After this was surprised that all looks good in one app and not working in another. Everything works great now, sorry for bothering.

It's not a bother at all. This step is so infrequent it is easily forgotten :)
