To remove the value from the array, then try the following:

onPressed: () async {
var clientCollection = Firestore.instance.collection("client");
clientCollection.document("confirmCode").updateData({
  "code" : FieldValue.arrayRemove([int.parse(confirmCode)])
}).then((_) {
  print("success!");
});                                          
},

Using FieldValue.arrayRemove you can delete an item from the array.
