Proposal

Please re-state the problem that we are trying to solve in this issue.

An extra space gets created between the first chat at the top and the title

What is the root cause of that problem?

In Step 4

Go to the LHN and unpin any other conversation you have and let the conversation you had with account B be at the top

The conversation with B is at the top, but actually in the reportIDs list here, there's another reportID of the IOU that's ordered above this report. The reason why that IOU report does not show is because its notificationPreference is hidden and will early return here.

When the user pin/unpin the chat report, the orders or that chat report and the IOU report will be switched, although the IOU report is hidden, it will still sometimes occupy space when the FlashList is rerendered because we always have the same estimatedItemSize here regardless of if we'll display the item or not.

That's why the blank space will show.

To quickly validate that this root cause is correct, we can simply add the below to here to make sure there's no "item included in list but does not render" and we'll see that the problem no longer occurs

if (report.notificationPreference === CONST.REPORT.NOTIFICATION_PREFERENCE.HIDDEN) {
    return false;
}

What changes do you think we should make in order to solve the problem?

We should consolidate the logic of "should we show this report in LHN?" in once place rather than two currently:

• In the filtering logic here
• In the item rendering here

We should move the logic in the item rendering to the reportIDs filtering logic, ideally here. So that if an item is not to be rendered, it will not appear in the reportIDs list passed into the FlashList at all. FlashList also expects the items passed to it to be rendered (because of the estimatedItemSize), not return null as we're doing.

So in this particular issue, the reportIDs list passed to FlashList will remain consistent when we pin/unpin the chat report, and the list will stay the same.

What alternative solutions did you explore? (Optional)

Looks like this is marked as android only issue.
@dukenv0307 can you please confirm? If so, please explain why this happens only on android.

📣 It's been a week! Do we have any satisfactory proposals yet? Do we need to adjust the bounty for this issue? 💸

[dukenv0307]

Looks like this is marked as android only issue.
@dukenv0307 can you please confirm?

@aimane-chnaif This issue happens on iOS as well, it's not Android-only.

[dukenv0307]

To quickly validate that this root cause is correct, we can simply add the below to here to make sure there's no "item included in list but does not render" and we'll see that the problem no longer occurs

if (report.notificationPreference === CONST.REPORT.NOTIFICATION_PREFERENCE.HIDDEN) {
    return false;
}

@aimane-chnaif I've added the above to the proposal, hope it makes it easier to validate the RCA is correct 👍

[melvin-bot]

@johncschuster, @aimane-chnaif Huh... This is 4 days overdue. Who can take care of this?

can you share a video of the behavior if you're unable to reproduce?

Instead, could you please share a video of the reproduction so I can make sure I'm following the steps correctly

I just followed the steps in the OP, I used an account with ~10 existing reports.

[Julesssss]

Ah, I forgot to unpin my chats.

Thanks for the comment, @aimane-chnaif! I'm having a hard time finding the PRs that fix this issue. Can you point me in the right direction?

Is it #38670, or is it something else?

I'm specifically looking for the merge date so I can calculate the payment date. Thanks!

No need new regression test. Already exists - https://expensify.testrail.io/index.php?/runs/view/20070&group_by=cases:section_id&group_order=asc&group_id=296775

[johncschuster]

Great! It sounds like we can go ahead and close this issue then. Thanks, everyone!
