By default, Blazor detects changes and reflects them in the UI automatically. However, there might be a situation where we have to manually trigger changes. StateHasChanged informs the component that its state has changed, but it does not render the component. The component will decide when to render itself. You can’t do that in a synchronous method, so you should async your code to give the component a chance to render.
