Giant crab spiders and flower crab spiders do share a lot in common.Definitely looks like a huntsman/sparassidae due to the flattened, forwards orientation of the legs and the fact that the front legs appear significantly longer than the back legs.
Was this caught in the Philippines (your location)? I did a google search for 'green huntsman spider' but it kept coming up with the Australian one.
I've heard that some juvenile huntsman are green before morphing into the standard brown/grey adult hues. How big is this pretty munchkin?
