flutter get inserted id from Firebase

I'm doing an app in flutter (ecommerce) when there is no cart created or opened I must create an order and get the id to add products, but I can not get the id of the order created

Future<void> createOrder() async {  
    Order order = new Order('Guatemala', new DateTime.now().toString(), '${widget.userId}-0', 0, widget.userId);
    var orderRs =_database.reference().child("orders").push().set(order.toJson());
 }

_orderList = new List();
_orderQuery = _database
  .reference()
  .child("orders")
  .orderByChild("order_status")
  .equalTo('${widget.userId}-0')
  .limitToLast(1);

_onProductAddedSubscription = _productQuery.onChildAdded.listen(_onEntryAdded);
_onProductChangedSubscription = _productQuery.onChildChanged.listen(_onEntryChanged);
_onOrderAddedSubscription = _orderQuery.onChildAdded.listen(_onOrderAdded);
_onOrderChangedSubscription = _orderQuery.onChildChanged.listen(_onOrderChanged);

I need to be able to create the order and get the id to add the corresponding detail

You can get the order ID by hanging on to the DatabaseReference that is created when you all push():

var orderRef =_database.reference().child("orders").push()
orderRef.set(order.toJson());
print(orderRef.key);
