Error while connecting Mongodb Atlas using Dart

Question

HandshakeException

This is how I'm trying to connect to the MongoDB:

class MongoDatabase {
  static connect() async {
   var db = await Db.create(MONGO_URL);
    await db.open();
    inspect(db);
    var status = db.serverStatus();`
    print(status);
    var collection = db.collection(COLLECTION_NAME);
    print(await collection.find().toList());****
  }
}

Which gives the following error:

E/flutter ( 2466): - HandshakeException: Handshake error in client (OS Error:
