Auto Migration Realm SDK Native Android

Hi Realm Community.

I,m start using Realm as a local database for our native android development ,no doubt realm has too much advantages over room and sql-lite .
But we stuck in problem ,we have an Client based applications and there is alot changes on every release now we need Auto Realm migration which automatically detects is something is changed in model class then update the database scheme without delete the existing user data same like sql-lite and room did .
We search alot tried all available code that will mentioned in realm doc and stackover flow ,github but not successful.
COULD you please help us or provide link how to do this or you have any auto migration code please send us .
Highly Appreciate.
