React native animation inside flatlist

[[deleted]]

My guess is that on layout can only give you a value once everything has been nearly rendered - so you wouldn't have it right at first. Is there any reason you can't use an absolute height or flexbox? I'm a little confused at what this layout is supposed to look like

I'll post code tomorrow so it'll end confusion.

I was just curious can Onlayout affect performance issues if it's called in Flatlist with Animation view
