The other day I built a flow action that generates random numbers. While doing it, I recorded the process, because we don’t have a lot of tutorial material on how you can turn a chunk of useful Apex code into a nice, declarative flow action.
For a general introduction to the invocable action interface, check this out.
So I was reading this thread that mentioned random numbers, and then I read this great post about building a Blackjack game out of flow, and the Monty Python-caliber dry humor (which may or may not be intentional; I haven’t figured that out yet) about the complicated math necessary to generate pseudo-randomness. And then I thought about how easy it is over in Apex-land to generate random numbers, so I built a Flow Action you can install into your org that takes two values and generates a true random number in that range.
