Yes. As doing Apex and it’s associated test class would take a very long time and only one person on the team has the skills. Flow is fairly straightforward. I’d prefer to use javascript though. 😉
… What if it’s possible to create this in skuid and have apex screen scrape the value skuid generates. Not that I have no clue what you’re doing :). And the time it takes to write the screen scraper would probably be approximate to the time it would take to transform this into apex code.
