xamarin forms change ffimage programmatically

Question

I'm struggling with changing an image programmatically.

In xaml I have an image like:

<ffimageloading:CachedImage x:Name="n3" Source="N3.png" ></ffimageloading:CachedImage>

In Code I have a TapGesture Recognizer:

var tapn3 = new TapGestureRecognizer();
            tapn3.Tapped += tapn3_Tapped;
            n3.GestureRecognizers.Add(tapn3);

And the corresponding event:

async private void tapn3_Tapped(object sender, EventArgs e)
        {
            string level = GetLevel();
            if (level == "N3") {
                   // n3.Source = new Image (Source "n3.png");
            } else {
                  // n3.Source = new Image (Source "n4.png");
            }
        }

GetLevel, returns a string which is stored in a SQLite DB, and that is working fine.

Off course, the commented lines is the functionality I'm not able to resolve.

If the images are already in your app, you should be able to do this: n3.Source = ImageSource.FromFile("n3.png");

Thanks. It was a lot easier htan I was trying. As it happens, sometimes, was trying to Nuke a Fly. – Gustavo Crispy Blanco Sep 14 '18 at 17:38
What if the file is SVG in the resource folder? – Ali Albahrani May 31 '21 at 03:32
