[HOLD for payment 2023-10-09] [HOLD for payment 2023-09-27] [Tracking] Improve ReportScreen re-renders

[mountiny]

Problem

The Report screen has a lot of performance bottlenecks. Mostly they are caused by unnecessary re-renders and given this component is very heavy to render, it can visibly slow down the App.

Solution

This is a tracking issue for multiple PRs and improvements which are found.

We are analysing the render cycles via Flipper Profiler and React Dev Tools and finding where are the bottle necks in the rendering of the component and its sub-tree.

So far we have found bugs regarding shared context and misuse of hooks that cause unnecessary re-renders. It might be an issue of death by a thousand paper cuts where seemingly innocuous changes cause large tree re-renders.

• Add initialValue, delayUpdates to allow components to eagerly render. react-native-onyx#329

Hey @ospfranco can you complete these steps for the Upwork job assignment? Thanks! #26087 (comment)

[ospfranco]

I'm working with margelo internally, do I need an upwork account @mountiny?

[mountiny]

@Christinadobrzyn @ospfranco is from Margelo so he does not use Upwork

[Christinadobrzyn]

Ah! So sorry for my confusion @ospfranco!

[Christinadobrzyn]
