onReordered toIndex jumps out of the data.length

[ilyago]

I'm using toIndex to read data inside onReordered and access its object value to recalculate LexoRank.
So if I drag any item at the bottom and go over the Flatlist box, the toIndex value becomes over the data.length

It gives me an error if I want to access the data array like removed[toindex].rank

I'm not sure if it's a bug, but for now, I have implemented workaround and made a comparison if it's in the range
