Now we still have the error of that.
Each child in illusion should have a unique key pops in the knees.
We have to add a key that is unique.
And so that we at low which card you want to manipulate.
Some people may said why we can't use index actually index may be changed because of the manipulation
of the card.
So there are just some exceptional cases that you think in that is save use when your list is static
while you will not change or this will never be ordered or you haven't do any many police or anything
like filtering.
Otherwise there indefinitely change.
For example if this card used to date had originally these index would be one but since the first one
already stated that it will change to zero.
So it will become changing differently and you may have some unexpected errors.
So we have to add a idea here.
Normally it should be returned from your database.
We may add some random test and just a different.
And then now we can pass these key positive top or IP to the key and save it.
The ERA has gone.
