How to clear jetpack datastore data on specific condition

Question

i've been using jetpack datastore for a while, but then i got a problem. I want to clear data in datastore when the app is destroyed. Im using jetpack datastore to persist data only in form

i've searched that sharedPreferences has a clear() function, is there a similar function for Jetpack Datastore ? and how can i use it ?

i found clear function in datastore documentation but there is no explanation on how to use it

Answer 1

Use this

dataStore.edit { 
        it.clear()
    }

Method description states

Removes all preferences from this MutablePreferences.

For proto datastore (Thanks to Amir Raza for comment)

datastore.updateData { 
    it.toBuilder().clear().build()
}

Answer 2

In case anyone wants to know how to remove a specific preference

context.dataStore.edit {
    it.remove(key)
}
