Creating the view

First, we will create a converter that will convert a byte[] to Xamarin.Forms.ImageSource. In the GalleryApp project, create a new folder named Converters, and inside the folder, create a new class named BytesToImageConverter:

public class BytesToImageConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
     {
         if (value != null)
         {
             var bytes = (byte[])value;
             var stream = new MemoryStream(bytes);
                
             return ImageSource.FromStream(() => stream);
        }
        
        return null;
 }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
         throw new NotImplementedException();
    }
}

To use the converter, we need to add it as a resource. We will do this by adding it to a ResourceDictionary object in the Resources property of GalleryView:

1. Open GalleryView.xaml.
