Recommended Usage with SbToastHost

For proper toast management (positioning, stacking, auto-dismiss), use SbToastHost:

@* In your layout or main component *@
<SbToastHost @ref="toastHost" Position="SbToastPosition.TopRight" />

@* Trigger toasts from your component *@
<SbButton OnClick="ShowSuccessToast">Show Success</SbButton>

@code {
    private SbToastHost? toastHost;
    
    private async Task ShowSuccessToast()
    {
        await toastHost!.ShowSuccessAsync("Operation completed!", "Success");
    }
}

See SbToastHost documentation for full details on toast management.
