What are all the Z Crystals available on each island, in the order that they are/can be found?

I know that there was a similar question, but this is different. I want to know them in the order they can be/are found, separated into islands. for instance, Flyinium Z is only available after visiting Poni Island, so put it after the other two in the Melemele section. You get me? the order per island is actually really important to me because I’m doing a fanfiction, and my protagonist doesn’t leave the island until all the Z Crystals possible are obtained. It’s important to me. Answer for Sun/Moon, please do not spoil US/UM at all.

If you use the earliest possible time you can obtain any of these Z Crystals, then this is your final list.

Or, for a more shortened version:Melemele has 3: Normal, Fighting, and FlyingAkala has 4: Water, Fire, Grass, and RockUla’ula has 7: Electric, Steel, Ghost, Psychic, Bug, Dark, IcePoni has 4: Poison, Ground, Fairy, Dragon

I wasn’t entirely sure if you wanted Pokemon specific Z Crystals as well, so I didn’t include them, but if you’d like me to, I can. Hope I could help!
