I'm creating a shopping application using Navigation Component(NavHost with BottomNavigationView)
The app has two tabs(Tab Home & Tab Categories). From Tab Home, the user can select a product and see the product detail and from Tab Categories, the user can navigate through categories. Now when the user opens a product from Tab Home, then if he/she selects Tab Category and then he/she selects Tab Home again, the Home destination will show but I want to show product destination and when the user clicks on back button show him/her home destination.
I've read these questions(Question 1 , Question2) but they don't use NavHost. I want to know is there any simpler or automatic way to accomplish this in NavHost?
