How do I create a computed column in an SQLite Table class definition in .Net Maui?

How do I create a computed column in an SQLite Table class definition in .Net Maui?

Here is the table...

[SQLite.Table("ItemHist")]
public class cl_ItemHist : TableData
{
	[NotNull, ForeignKey(typeof(cl_Stores))]
	public int Store_id { get; set; }
       
	[NotNull]
	public DateTime PurchDate { get; set; }
        
	[NotNull, ForeignKey(typeof(cl_Items))]
	public int Item_id { get; set; }
       
	[NotNull] 
	public float ItemQty { get; set; }
       
	[NotNull]
	public float TotalPrice { get; set; }
       
	[ForeignKey(typeof(cl_SaleCodes))]
	public int SaleCode_id { get; set; }

	[NotNull, ForeignKey(typeof(cl_Uom))]
	public int UnitPriceUom_id { get; set;}
        
	[NotNull, DefaultValue(0)]
	public int Purchased { get; set; }

	// References cl_Stores
	[OneToOne(CascadeOperations = CascadeOperation.CascadeRead)]
	public cl_Stores StoreName { get; set; }
        
	// References cl_Items
	[OneToOne(CascadeOperations = CascadeOperation.CascadeRead)]
	public cl_Items ItemName { get; set; }
        
	[OneToOne(CascadeOperations = CascadeOperation.CascadeRead)]
	public cl_Items ItemSize { get; set; }

	// References cl_SaleCodes
	[OneToOne(CascadeOperations = CascadeOperation.CascadeRead)]
	public cl_SaleCodes SaleCode { get; set; }

	// References cl_Uom from cl_Items
	[OneToOne(CascadeOperations = CascadeOperation.CascadeRead)]
	public cl_Uom Uom { get; set; }
}

The computed column I want to include contains three existing columns:

(TotalPrice / (ItemSize * ItemQty))

To exclude the computed property from sqlite, mark it [Ignore].

[Ignore]
public float MyComputedColumn => . . .;

However, you mention "dynamic". If you need display to be updated immediately, on any change of the three properties that affect this column, you’ll need additional code in the setters of those three properties. And class cl_itemHist will need to implement INotifyPropertyChanged.
