How to encrypt the SQLite database in Flutter?

Question

I am creating a database in Flutter by the following code, is there any way we can encrypt the database?

Is there any library available for Flutter?

initDb() async {
    io.Directory documentsDirectory = await getApplicationDocumentsDirectory();
    String path = join(documentsDirectory.path, "test.db");
    var theDb = await openDatabase(path, version: 1, onCreate: _onCreate);
    return theDb;
  }

Pointy Castle seems to be the encryption library of choice at the moment.
