How to store fragment state in activity android Kotlin

Question

Hey I am working on androidx fragment. I want to ask is there any way to restore state of fragment in middle of language change configuration. For example I have 1 activity and 4 fragments.

Activity

1st Fragment > 2 Fragment > 3 Fragment > 4 Fragment

Like this I have fragments in single activity. In 1st Fragment I am calling 3 api call through retrofit. I have some callbacks in each fragments. In 1st Fragment I have 2 callback which execute api calls.

Also I have logic to jump directly in 3 Fragment with calling each fragment to go and showing loading spinner to user. Now main scenario starts.

when I am in 3rd Fragment. I change my device language and my 1st fragment callback not called and the result is blank screen. So I am thinking to store my fragment state and restore when created the activity may be that would help me.

Please I checked this answer. I read somewhere Is to use viewmodel to save state of fragment. Using koin for Dependency Injection for my viewmodel. I need latest answer and how to store whole fragment instance?. Please don't add link of google doc. I already tried from there and it didn't work for me. Thanks
