Properly calculate alwaysUse24HourFormat on MacOS #53795

kpsroka · 2024-07-10T10:28:27Z

Moves the implementation if isAlwaysUse24HourFormat from iOS's FlutterViewController internals to common utility, and makes use of it on MacOS in order to return correct value of alwaysUse24HourFormat.

This PR partially resolves #32006.

Note that on iOS 16 and MacOS 13 , there is a new API for obtaining this information: https://developer.apple.com/documentation/foundation/locale/components/3952289-hourcycle. However, to keep things simpler, I wanted to not include changes to the logic.

It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption to this rule, contact "@test-exemption-reviewer" in the #hackers channel in Chat (don't just cc them here, they won't see it! Use Discord!).

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing.

LGTM. This seems like a straightforward refactor. Not sure if this needs a test since it only moves things from iOS to darwin embedder. Also I'm not sure how to test this given that the behavior depends on system settings. @cbracken, any ideas?

cbracken · 2024-07-12T18:30:52Z

Also I'm not sure how to test this given that the behavior depends on system settings.

In the usual case, we'd say extract out a thin utility class that wraps the system setting and then write a test of the usage site against a mock. ~~In this case, this is just a refactoring that factors out the thin wrapper that wraps the system setting.~~ Since this also makes use of this in the mac embedding, we should add a test there.

You could write a test against the existing usage that just tests that the value set in the FlutterHourFormat is the value that's used. Probably not too much effort, ~~but I think a case could also be made for requesting a test exemption.~~

Looks great! Thanks for the patch!

In this case, this is just a refactoring that factors out the thin wrapper that wraps the system setting.

This isn't just a refactoring though; the purpose of this PR is to change the behavior of the macOS embedding. That's a behavioral change that should not regress, and thus should be tested.

(In this case I would suggest a test that onSettingsChanged: call the channel with expected values, probably using an injected formatter as cbracken suggested.)

From PR triage: It looks like this PR is waiting for a test to be added, correct?

Overall looks good, just a few nits and suggestions.

kpsroka · 2024-08-01T09:50:55Z

I think that the PR is ready for merge. @cbracken please merge/add "autosubmit" [if you agree].

kpsroka · 2024-08-01T09:51:38Z

Note that flutter/flutter#32006 is best left [re-]opened, and updated to refer only to textScaleFactor

cbracken · 2024-08-01T18:51:37Z

Thanks for the fix, @kpsroka! Merged!
