Random order of list?

hi do you know how to make the list order random? Because if i understand correct if you dont have any ordering value the list shows in the same order as in firebase and i want it to be random.
i have tried things like this
SORT_BY_KEY(data.postinfo1, RANDOM(data.postinfo1[0].newprice))
but dont work

Thank you in advance

You can use SHUFFLE to randomize a List

Dont put the index (0)
