I'm using datastore preferences but I'm currently unable to set a null/nullable value (see TestRepository from the attached sample project).
From a first look at the code I believe the value parameter type of the set operator of MutablePreference should be nullable since the null value is actually handled inside the setUnchecked function.

public operator fun <T> set(key: Key<T>, value: T) {
    setUnchecked(key, value)
}

internal fun setUnchecked(key: Key<*>, value: Any?) {
    checkNotFrozen()

    when (value) {
        **null -> remove(key)**
        is Set<*> -> preferencesMap[key] = Collections.unmodifiableSet(value.toSet())
        else -> preferencesMap[key] = value
    }
}

I have noticed this parameter is already reported as nullable in the generated metadata API but that does not reflect the current code.

Also the documentation for the set operator is wrong: in the parameters table the second parameter should be value instead of key.
