		// Call After OnDisappering
        public void Disposing(View content, PopupPage page)
        {
			// Dispose Unmanaged Code
        }
        
        // Call After OnAppering
        public async Task Appearing(View content, PopupPage page)
        {
            // Show animation
            await content.FadeTo(1);
        }
        
        // Call Before OnDisappering
