Navigation, Saving fragment state

[ibrahimAlii]

Hi, I'm was trying to save fragment state, Is there a suggested way to use while using Navigation component?

It's like open new fragment without lose the previous fragment states.

Do you really need to save fragment state while using Navigation?

Yes, I do. It's like using FragmentTransaction.show()/hide()

Yes, I do. It's like using FragmentTransaction.show()/hide()

You are right.
Using FragmentTransaction.add()/show()/hide() by override the method navigate() of FragmentNavigator

In the case of that repo, fragments are not destroyed when navigating but they are recreate view all the time by onCreateView(). I want when I pop fragments from backstack, they are not recreate view like I do with the FragmentTransaction

The reason fragments are recreated is using attach/detach in navigate method of KeepStateNavigator class, so you should know that the correct is use show/hide instead of attach/detach.

yeah, yeah, I know. haha. But the point is I haven't succeed yet when I replace attach/detach by show/hide in the KeepStateNavigator class :D
