For getting all keys

suspend fun Context.readAllKeys(): Set<Preferences.Key<*>>? {
    val keys = dataStore.data
        .map {
           it.asMap().keys
        }
    return keys.firstOrNull()
}

for getting value by it's key

suspend fun Context.getValueByKey(key: Preferences.Key<*>): Any? {
    val value = dataStore.data
        .map {
            it[key]
        }
    return value.firstOrNull()
}
