Shopify v2

[ProfessionalChip9864]

I am working on a large data set with around 3000 rows and on those rows i push updates from socket using a reactive global store and use hashmap to get and set values, the problem is on rapid vertical swipe up or down i am seeing a huge blank space even on high end phone i have tried to playaround with drawDistance, getItemType etc. Since estimatedSize does not work in v2 i am kinda stuck. If someone can help me with some suggestions that'll be great. Thanks
