patch static method
Apply patch to storage.
It will do deletion first, then set items.
Implementation
static Future<void> patch({
Iterable<String>? itemsToDelete,
Map<String, dynamic>? itemsToSet,
}) async {
assert(_box != null, 'call "prelude" first');
assert(itemsToSet != null || itemsToDelete != null, 'Nothing to patch.');
if (itemsToDelete != null) await _box!.deleteAll(itemsToDelete);
if (itemsToSet != null) await _box!.putAll(itemsToSet);
}
