Component Bus

Consider using the Blazor Component Bus for messaging instead of Fluxor. Fluxor is great for when you really need its functionality, but it requires you to write a fair amount of boilerplate, so consider lighter-weight options first. The Bus allows Blazor components to publish and subscribe to messages that you create.

Create a message with either no payload, or whatever payload you require:

public record SomethingHappenedMessage();
public record SomeDataMessage(string StringData, int IntData);

In the publishing component:

[Inject] private ComponentBus Bus { get; set; } = default!;

private async Task OnClick()
{
  await Bus.Publish(new SomeDataMessage("Hello", 5));
}

And in the subscribing component:

[Inject] private ComponentBus Bus { get; set; } = default!;

protected override void OnInitialized()
{
  base.OnInitialized();
  // Other code
  Bus.Subscribe<SomeDataMessage>(HandleSomeDataMessage);
}

private void HandleSomeDataMessage(MessageArgs args)
{
  InvokeAsync(() => // 
  {
  var message = args.GetMessage<SomeDataMessage>();
  // Do something with message.StringData and message.IntData
  StateHasChanged();
  });
}
