Touch events not working in FlashList v2

[owencraston]

Description

We (MetaMask) are using FlashList V2 to render our list of accounts. The user can open this list of accounts, tap one of them and this will change their globally selected account. However we noticed in testing that sometimes touch events are not being registered at all. This leaves the user tapping frantically with no feedback. This could be that the touch events are not firing, or it could be that the onPress is not registered for that cell. Either way the issue is weird and causing a UX regression in our app. The other curious aspect of this bug is that the issue does not occur every time you open the list but instead seems to happen randomly if the user touches the list quickly enough. This issue seems to only be effecting Android. If the user scrolls on the list, all cells become touchable and the list works as expected. Something about the initial load/lack of scrolling is causing this weird behaviour.

related issue: MetaMask/metamask-mobile#20735

Current behavior

1. User opens account list
2. User quickly taps an account to change their selected account preference
3. Tap event does not register and leaves the list open with no action/feedback.

Expected behavior

• When the user touches the account cell, it should update the state to show that this is the new current selected account and close the list.

Reproduction

1. Our code is open source and can be viewed/run here.
2. Once you have setup the codebase, you can run the app locally via
   1. yarn setup
   2. yarn start:android
   3. Once the app builds, disable dev mode via developer settings (shake device, open dev options and toggle off dev mode)
   4. If this is too challenging I can try and find an easier way to share the code.3. create or import a wallet via the onboarding flow
3. once onboarding is complete, you should be taken to the main home page
4. click on the little drop down menu shown in the top left corner (for a new account it should say "Account 1")
5. the list should open in a bottom sheet
6. without scrolling on the list, quickly tab another account.
7. See that the touch event is not triggering the on press handler for that cell

• Reproducing this issue is challenging since it does not occur every time. The user must quickly tap on the cell in the accounts list for this error to occur.
• Once the user scrolls on the screen, all cells become touchable. Therefore you must tap the screen before you do any scrolling in the list.
• I was not able to reproduce this issue in dev mode so you need to turn that of (via developer menu)
• This issue only seems to occur on Android phones. We tested with the latest pixel 8 so the performance of the phone is likely not the issue.

Platform

• iOS
• Android
• Web (if applicable)

Additional context

What we have tried to fix the issue?

• Updating to v 2.1.0 did not fix the issue (our current version is 2.0.3
• I did some research that led me to believe this issue is a result of having the FlashList rendered inside a BottomSheet component using the GestureHandler (described in GestureHandler issue).
  • I tried moving our FlashList component outside of the BottomSheet and into a proper page and removing the renderScrollComponent={ScrollView as React.ComponentType<ScrollViewProps>} but this did not solve the issue.

Key Files

• Our FlashList implementation lives here inside the MultichainAccountSelectorList
• This component is rendered inside the AccountSelector parent component.
• The parent renders this list inside a bottom sheet which is implemented here.

Checklist

• I've searched existing issues and couldn't find a duplicate
• I've provided a minimal reproduction (Expo Snack preferred)
• I'm using the latest version of @shopify/flash-list
• I've included all required information above

I noticed that this issue occurs if you tap the screen as soon as it opens. Do not let the list fully render. If you do this, it goes into a broken state.
