Hello guys,
i'm using Xamarin Forms to develope my app on both iOS and Android
I have 2 page:
1. A Custom Renderer Page for each platform, it include a listview to show list of item in SQLite database
2. A Result Page to show data when I press button to show camera and link item to taken image. This page i using NavigationAsync to show up
The question is, How to update list of item when i already link item to image and press back button?

Thanks.
