Excelente resource thanks!!!

This is an implementation using just one file for the component and implementing the Online/Offline mark. Just in case someone needs it

@inject INetworkState State

@if (IsOnline)
{
   <span class="btn-success">Online</span>
}
else 
{
    <span class="btn-danger">Offline</span>
}

@code
{
    protected bool IsOnline => State.IsOnline;

    protected override void OnInitialized()
    {
        base.OnInitialized();

        State.StatusChanged += StateHasChanged;
    }

    public void Dispose()
    {
        State.StatusChanged -= StateHasChanged;
    }
}
