Details

We cannot use ScrollView with SelectionList because it is anti-pattern and will lead to performance issues and bugs.

With this PR, we are removing the usage of ScrollView and adding the extra components as either listHeaderContent or listFooterContent

Fixed Issues

$ #48974
PROPOSAL:

Tests

  • Only on Dev environment

PREREQUISITES: all betas or workspace feed beta enables

  1. Enable Expensify Card in More Features
  2. Add a new bank account and choose this bank for Expensify Card
  3. Right after adding a bank and enabling the card on the Expensify Card page go to Settings
  4. Go to Settlement Account settings page

Verify that we do not get the error: VirtualizedLists should never be nested inside plain ScrollViews with the same orientation because it can break windowing and other functionality - use another VirtualizedList-backed container instead.


  • Precondition:
  1. Comment this line of code to shouldShow={false}.

  2. Have 2 bank accounts set up on wallet page

  3. Go to settings/wallet/choose-transfer-account

Verify that we do not get the error: VirtualizedLists should never be nested inside plain ScrollViews with the same orientation because it can break windowing and other functionality - use another VirtualizedList-backed container instead.

  • Verify that no errors appear in the JS console

Let's wrap it by View Component. This is draft implementation. YOu can apply more style to View to display the correct UI

             <View style={[styles.flexRow]}>
                <SelectionList
                    ......
                />
            </View>
            <MenuItem
                onPress={navigateToAddPaymentMethodPage}
               .......
            />

@DylanDylann Your solution doesn't work well with scrolling or when we have several bank accounts, take a look:

@DylanDylann @allgandalf One easy way to solve this particular case is to use the listFooterContent of SelectionList component, which allows us to render the button at the bottom of the list:

            <SelectionList
                sections={[{data}]}
                ListItem={RadioListItem}
                onSelectRow={(value) => {
                    const accountType = value?.bankAccount?.accountType;
                    const accountData = value?.bankAccount?.accountData;
                    selectAccountAndNavigateBack(accountType, accountData);
                }}
                shouldSingleExecuteRowSelect
                shouldUpdateFocusedIndex
                initiallyFocusedOptionKey={walletTransfer?.selectedAccountID?.toString()}
                listFooterContent={
                    <MenuItem
                        onPress={navigateToAddPaymentMethodPage}
                        title={
                            walletTransfer?.filterPaymentMethodType === CONST.PAYMENT_METHODS.PERSONAL_BANK_ACCOUNT
                                ? translate('paymentMethodList.addNewBankAccount')
                                : translate('paymentMethodList.addNewDebitCard')
                        }
                        icon={Expensicons.Plus}
                    />
                }
            />

I tested on iOS Native, Safari MWeb and Chrome, seems to work well. We should test on Android too.

The only drawback of this approach is that by supplying the listFooterContent prop, SelectionList won't render the Show More button anymore if the list has more than 500 items, but I think it's unlikely for an user to have so many bank accounts. If this is a problem we should explore the FlatList "wrapper" solution then.

SelectionList won't render the Show More button anymore if the list has more than 500 items, but I think it's unlikely for an user to have so many bank accounts.

This would really be an edge case, and in general no single user would have 500+ bank accounts, so i guess this solution would work good, I will also apply this in settlement account page as well. thanks for looking out @fabioh8010

  • If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.
  • I have checked off every checkbox in the PR reviewer checklist, including those that don't apply to this PR.
