Hello Osayed,
This is a common issue when the ListView component is inside StackLayout and the ItemSource property is initially an empty list (or empty ObservableCollection), the ListView is not visible on screen, even after items are added later on.

At the moment, suitable workaround I could suggest is replacing the StackLayout with Grid layout.
For more details, please take a look at the topic in our Forum about ListView not showing up
