Title: Performance Issues with Large Datasets in Flash List

[Encoded99]

Description: I’m experiencing performance degradation with Shopify Flash List when handling larger datasets. As the data size grows, scrolling becomes laggy, and rendering slows down. These issues persist despite optimizing my code and implementing a static version of my feed to minimize re-rendering.

Steps Taken:

Optimized lazy rendering props (initialNumToRender, maxToRenderPerBatch).

Created a static feed equivalent to reduce rerenders.

Despite these efforts, the problem persists, particularly with datasets larger than 30 items.

I would appreciate guidance or updates to improve Flash List's handling of large datasets, or documentation for efficient scrolling with larger data sizes

30 isn't large. FlashList can easily handle thousands of items. Will you be able to share a video or sample?
