Question - use MapContext parameters in Map method in TypeAdapter configs

[naisyrkdev]

Hi guys, I have in db columns like this NameEN, NameFR, NameDE etc. becouse this is needed for my specific example.
Before I had just one column Name, I just wanna change map config.

public class InventoryItemClientModelMap : IRegister
{
    public void Register(TypeAdapterConfig config)
    {
        config.NewConfig<AppItem, InventoryItemClient>()
               .Map(dest => dest.Id, src => src.Id)
               .Map(dest => dest.Name, src => src.GetLocalizedName((string)MapContext.Current.Parameters["lang"])) ;
    }
}

var clientModel = new InventoryItemClient();
using (var scope = new MapContextScope())
{
    scope.Context.Parameters["lang"] = request.Lang // "en", "de" etc, its good;
    clientModel = appItem.Adapt<InventoryItemClient>();
}

Get localized method, just for additonal information

  public static string GetLocalizedName(this AppItem appItem, string langCode)
  {
      switch(langCode)
      {
          case (""):
          case ("en"):
          case ("en-US"):
          case ("en-EN"):
              return appItem.Name;
          case ("de"):
              return appItem.NameDE;
          default:
              return string.Empty;
      }
  }

This throw null error.
Any way to do something like this? Maybe there is another approach to reach result I want (use passed value in adapter in map method)

I had to do null check with entity and null check if MapContext.Current.Parameters["lang"], now working properly as expected.
