fix: mobile doesn't need manual focus anymore for autoFocus

[hannojg]

Explanation of Change

There is a bug in react native where calling textInputRef.focus() doesn't focus the text input. That is the reason for the bug which this PR wants to fix. This kind of bug doesn't happen when we use the autoFocus native prop on the TextInput.
I figured, instead of going down the rabbit hole and analyzing why .focus() became broken in certain conditions, we should start to rely on the autoFocus prop again.

In the past we use to manually call textInputRef.focus() to circumvent a bunch of bugs. However, now that we are:

• on the new arch
• use native-stack for navigation

those previous problems don't really exist anymore, and it seems safe to remove our manually calling code. (I think it's also cleaner to remove our "custom" code and instead rely on the build in APIs such as the autoFocus prop).

Note

For now I have kept the shouldDelayFocus prop. I think we should be able to remove this prop as well as it was only helping us to circumvent certain bugs, but:

• I think it would be better to handle this in a separate PR
• On android there was one case where the input wasn't focused just using the autoFocus prop and we need to investigate why that happens

Opened a follow up ticket here:

Tests

• Open the app on a physical iOS device
• Open the sign in page
• Enter your email (note: make sure that the email address is added to your iOS mail app as well)
• When being brought to the magic code page
  1. Make sure that the keyboard has switched to a numeric input
  2. open your mail app and wait for the code to arrive, don't open it
• Go back to the app and make sure that it auto suggests the magic code

Additionally make sure all other text inputs when navigating through the app are still being auto focused.

PR Author Checklist

• I linked the correct issue in the ### Fixed Issues section above
• I wrote clear testing steps that cover the changes made in this PR
  • I added steps for local testing in the Tests section
  • I added steps for the expected offline behavior in the Offline steps section
  • I added steps for Staging and/or Production testing in the QA steps section
  • I added steps to cover 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 tested this PR with a High Traffic account against the staging or production API to ensure there are no regressions (e.g. long loading states that impact usability).
• I included screenshots or videos for tests on all platforms
• I ran the tests on all platforms & verified they passed on:
  • Android: Native
  • Android: mWeb Chrome
  • iOS: Native
  • iOS: mWeb Safari
  • MacOS: Chrome / Safari
  • MacOS: Desktop
• I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
• I followed proper code patterns (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 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
    • If any non-english text was added/modified, I used JaimeGPT to get English > Spanish translation. I then posted it in #expensify-open-source and it was approved by an internal Expensify engineer. Link to Slack message:
  • 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 either coming verbatim from figma or has been approved by marketing (in order to get marketing approval, ask the Bug Zero team member to add the Waiting for copy label to the issue)
  • 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 followed the guidelines as stated in the Review Guidelines
• I tested other components that can be impacted by my changes (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar are working as expected)
• 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.ts or at the top of the file that uses the constant) are defined as such
• I verified that if a function's arguments changed that all usages have also been updated correctly
• 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(theme.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 the PR modifies the UI (e.g. new buttons, new UI components, changing the padding/spacing/sizing, moving components, etc) or modifies the form input styles:
  • I verified that all the inputs inside a form are aligned with each other.
  • I added Design label and/or tagged @Expensify/design so the design team can review the changes.
• 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.
• I added unit tests for any new feature or bug fix in this PR to help automatically prevent regressions in this user flow.
• 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.

@hannojg Although the field is focused, but the keyboard does not appear. Is that expected?

[hannojg]

Although the field is focused, but the keyboard does not appear. Is that expected?

I know that there are certain conditions in which we will display the keyboard in the chat. We don't display it per se for every chat. I would need to lookup the conditions for that, hold on …

[allroundexperts]

This is happening on dev as well btw, so it shouldn't block the approval.

[mountiny]

Thanks, changes look good to me

[mountiny]

Is this issue happening in dev too? #54755 (comment) I think we should open the keyboard everytime

[hannojg]

I think there is custom behavior to when the keyboard should open when opening a chat (I never understood why though, but there were some reasons for that). On production the keyboard doesn't open for me for every chat.
So I think this is a feature, not a bug.

[mountiny]

got it

[hannojg]

😂 😂

when I have time I will find the specific code lines that control that behaviour
