I should be able to do:
db.transaction([storeName]);
But lib/dom/generated/src/frog/IDBDatabase.dart has this signature:
_IDBTransactionJs transaction(String storeName, int mode) native;
Two problems:
First argument should be a List<String>.
Second argument should be optional.
(Technically, both arguments are optional: https://developer.mozilla.org/en/IndexedDB/IDBDatabase#transaction())
