So what should I be putting in OnResume, OnAppearing, OnDisappearing? A lot of people say "clean up" but Im not sure what that means. Ive seen other people say I should be unsubbing from events? I want to fool proof my pages and have ideal mem management. What are you guys using these events for? Are they safe to be used versus the native ones, because Ive also heard they can fire at weird and different times on the different platforms.
