Blazor hybrid LocalStorage consume into CS class file

So this is my razor code file

@inject Blazored.LocalStorage.ILocalStorageService localStoragevar test = await localStorage.GetItemAsync<String>("MyKey");

And this WORKS.

So i need to get the data into Utility.cs class

internal class Utility {     protected readonly ILocalStorageService _localStorage;     public Utility(ILocalStorageService LocalStorage)     {         _localStorage = LocalStorage;     }     public async Task updateLocalStorage()     {         await _localStorage.SetItemAsync("test", "123");     }     public async Task getLocalStorage()     {         ResponseLogin login = await _localStorage.GetItemAsync<ResponseLogin>(LocalStorageNames.ResponseLogin);     } }

and into MauiProgram.cs i added this:

builder.Services.AddScoped(p => new Utility(p.GetRequiredService<ILocalStorageService>()));

But, i didn't understand why my Utility class keep null when i start.. i can't understand how to init this class

Utility _utility = new Utility(????);

Any help? I need to use this class like a singletonAlso tried this:

[Inject]public blazored.LocalStorage.ILocalStorageService localStorage { get; set;}

But always null...
