ANDROID - Jetpack Compose: how to implement theme settings?
I'm having hard times trying to implement a preference who switch the application theme.
Normally I would be able to do it with XML but with Jetpack Compose I saw that the best practice is to use DataStore (https://developer.android.com/topic/libraries/architecture/datastore)
Someone please, can explain me from scratch how to store a preference and change the whole application theme...
