Optimize FlatLists #19

Open mvaivre opened 1 year ago

mvaivre commented 1 year ago

We're seeing the following warning: VirtualizedList: You have a large list that is slow to update.... We're already memoizing the flat list items, however more can probably be done. We're using such lists across the whole app: improving this will probably have a great impact on smoothness & loading time.

Imo, none of this can grow to a size that will impact performance. I tried adding 100 contacts and I didn't get any warnings. So, I would leave this task for after the initial release. It requires quite a bit of work and I'd rather focus on other more pressing issues.

@mvaivre WDYT?
