ViewModel

public class ItemInfoRepository
{
    #region Properties
    public ObservableCollection<ItemInfo> Info { get; set; }
    public Command<object> FavouriteCommand { get; set; }
    #endregion

    #region Constructor
    public ItemInfoRepository()
    {
        FavouriteCommand = new Command<object>(OnFavouriteClicked);

        Info = new ObservableCollection<ItemInfo>();
        Info.Add(new ItemInfo() { Name = "Cheese burger", Description = "Hamburger accompanied with melted cheese. The term itself is a portmanteau of the words cheese and hamburger. The cheese is usually sliced, then added a short time before the hamburger finishes cooking to allow it to melt.", FavouriteIcon = "\uf004" });
        Info.Add(new ItemInfo() { Name = "Veggie burger", Description = "Veggie burger, garden burger, or tofu burger uses a meat analogue, a meat substitute such as tofu, textured vegetable protein, seitan (wheat gluten), Quorn, beans, grains or an assortment of vegetables, which are ground up and formed into patties.",  FavouriteIcon = "\uf0f4" });
