refactor(28902): [FlashList migration] PaymentMethodList #29095

adhorodyski · 2023-10-09T14:43:48Z

Details

This PR introduces FlashList as a new dependency and refactors PaymentMethodList component to use it instead of react-native's FlatList.

Before

Native Android, debug build with dev js bundle turned off, 100 items:
https://github.com/Expensify/App/assets/42047036/f7b51a2a-ef84-4038-875c-809a01afd2e0
Some really visible blank areas.
Native Android, adhoc release build, 1000 items:
https://github.com/Expensify/App/assets/42047036/f4bc8bc4-bce0-43b2-affc-1f36fee982dc
Visible blank areas, even though the FPS is around 55-60, content is mostly invisible when fast scrolling.
Native Android, adhoc release build 1000 items heavy usage results from Flashlight:

Little to no visible blank areas, definitely better than before.

Little to no visible blank areas.
Native Android, adhoc release build 1000 items heavy usage results from Flashlight:

Summary

Migrating to Flashlist resulted in a lower memory and CPU consumption, FPS stayed at the high level and it has eliminated blank areas especially when fast scrolling.
As per the numerous Slack discussions, the underlying components on the renderItem such as MenuItem with PressableWithSecondaryInteraction inside can be improved as a separate effort.

Hey @burczu, can I please ask for your review in here? I've rebased this over the latest main so it's up to date :) Let me know if I can help you in any way.

burczu · 2023-10-17T08:13:58Z

Hey @adhorodyski! Sorry for the delay, I was quite overloaded with tasks recently. I should move things forward here today.

Reviewer Checklist

I have verified the author checklist is complete (all boxes are checked off).
I verified the correct issue is linked in the ### Fixed Issues section above
I verified testing steps are clear and they cover the changes made in this PR
- I verified the steps for local testing are in the Tests section
- I verified the steps for Staging and/or Production testing are in the QA steps section
- I verified the steps cover any possible failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
- I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
I checked that screenshots or videos are included for tests on all platforms
I included screenshots or videos for tests on all platforms
I verified tests pass on all platforms & I tested again on:
- Android: Native
- Android: mWeb Chrome
- iOS: Native
- iOS: mWeb Safari
- MacOS: Chrome / Safari
- MacOS: Desktop
If there are any errors in the console that are unrelated to this PR, I either fixed them (preferred) or linked to where I reported them in Slack
I verified proper code patterns were followed (see Reviewing the code)
- I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick).
- I verified that the left part of a conditional rendering a React component is a boolean and NOT a string, e.g. myBool && <MyComponent />.
- I verified that comments were added to code that is not self explanatory
- I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
- I verified any copy / text shown in the product is localized by adding it to src/languages/* files and using the translation method
- I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
- I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is approved by marketing by adding the Waiting for Copy label for a copy review on the original GH to get the correct copy.
- I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.
- I verified the JSDocs style guidelines (in STYLE.md) were followed
If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
I verified that this PR follows the guidelines as stated in the Review Guidelines
I verified other components that can be impacted by these changes have been tested, and I retested again (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar have been tested & I retested again)
I verified all code is DRY (the PR doesn't include any logic written more than once, with the exception of tests)
I verified any variables that can be defined as constants (ie. in CONST.js or at the top of the file that uses the constant) are defined as such
If a new component is created I verified that:
- A similar component doesn't exist in the codebase
- All props are defined accurately and each prop has a /** comment above it */
- The file is named correctly
- The component has a clear name that is non-ambiguous and the purpose of the component can be inferred from the name alone
- The only data being stored in the state is data necessary for rendering and nothing else
- For Class Components, any internal methods passed to components event handlers are bound to this properly so there are no scoping issues (i.e. for onClick={this.submit} the method this.submit should be bound to this in the constructor)
- Any internal methods bound to this are necessary to be bound (i.e. avoid this.submit = this.submit.bind(this); if this.submit is never passed to a component event handler like onClick)
- All JSX used for rendering exists in the render method
- The component has the minimum amount of code necessary for its purpose, and it is broken down into smaller components in order to separate concerns and functions
If any new file was added I verified that:
- The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
If a new CSS style is added I verified that:
- A similar style doesn't already exist
- The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(themeColors.componentBG)
If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
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.

@adhorodyski Did you notice that on native devices we get such warning while opening page with the FlashList - can we get rid of it?

adhorodyski · 2023-10-17T11:27:07Z

I don't recall having it at the later stage of development (I've seen this at the start though) - let me handle this and get back to you, thanks!

adhorodyski · 2023-10-18T11:14:35Z

I'm currently getting other errors after rebasing over main, probably related to #29839 - will get back to debugging when it's fixed.

adhorodyski · 2023-10-23T11:23:17Z

@burczu looks like setting the minHeight on a parent view helped with this issue, please let me know if you'd spot anything else :)

burczu

Confirmed that the warning does not show up anymore.

LGTM then.

@mountiny from my end it's ready to be merged, please let me know if there's anything I can add in here :)

@adhorodyski I just realized we already had a const for this optionRowHeight – in your next PR can you please get rid of this paymentMethodHeight and instead use optionRowHeight?

Sure thing, will update in the morning! 🙂

-            />
+            <View style={[style, {minHeight: variables.paymentMethodHeight}]}>


I believe this may have caused #33075 as variables.paymentMethodHeight is only equal to 1 item's height, but we can have multiple cards. More details here.
