I know that it is possible to create a IndexedDb at client side, but I was wondering if it possible to create a key/value store server Side. In that case we could use that db as a cache server or even as an elasticSearch server, or maybe replace a SQL or NoSQL database

Unfortunately it is not possible to create an IndexedDb on the server in Dart. The implementation primarily leverages the APIs provided by the client-side navigator (eg. Chrome, Firefox, etc). IndexedDb is a developing web standard which will hopefully be implemented in all browsers in the future. In this way, Dart is basically using APIs to access a separate database (albeit a very simple one). It is not implemented in Dart itself.
That said, in addition to other serverside database APIs, there is also a Dart client interface for memcache which can be run on the sever to connect to a memcache instance
