created issue #1

Feb 26, 2024 02:02PM

Jetpack Compose version: 2024.02.01
Jetpack Compose component used: material3:1.2.0
Android Studio Build: N/A
Kotlin version: 1.9.22

As I was calling the bottom sheet, I was calling the colors function like this

colors = NavigationBarItemDefaults.colors(
  indicatorColor = MaterialTheme.colorScheme.surface,
  selectedIconColor = MaterialTheme.colorScheme.onSurface,
  unselectedIconColor = MaterialTheme.colorScheme.onSurface,
),

but the latest material3 version is not providing sane defaults as it used to for the colors that I am not specifying explicitly. Instead I get black text on dark and light mode since I am not specifying a specific color for selectedTextColor and unselectedTextColor.

These lines here https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/material3/material3/src/commonMain/kotlin/androidx/compose/material3/NavigationBar.kt;l=312-321?q=NavigationBarItemDefaults are the ones that probably break this behavior. Which was introduced here https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/material3/material3/src/commonMain/kotlin/androidx/compose/material3/NavigationBar.kt;l=312-321?q=NavigationBarItemDefaults This Unspecified color is then used over here https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/material3/material3/src/commonMain/kotlin/androidx/compose/material3/NavigationBar.kt;l=445-451?q=NavigationBarItemDefaults Interestingly, the deprecated method which says "Use overload with disabledIconColor and disabledTextColor", does seem to properly set some sane defaults for the parameters you may not be specifying.

In contrast, for NavRail this was not broken in the latest update, see here https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/material3/material3/src/commonMain/kotlin/androidx/compose/material3/NavigationRail.kt;l=308-317?q=NavigationRailItemDefaults

I would expect here to get either a more sane default meaning something from the MaterialTheme which is more likely to have the right value for dark and light mode like it did before. This simply breaks the layout completely as the text is completely illegible by default.

commit c60f33e229e31ab328ef6b59dab63b264954831c

Semantics no-op cleanups

Partly in response to lmr's broad code review, I did a pass of
superficial API/implementation cleanup. The main changes are:

- I changed each Boolean SemanticsProperty where false is equivalent to
not being present to take "Unit" instead. This is conceptually
clearer: it avoids questions like "can I cancel out a semantics from a
merged child by setting it to false?" Because "property = Unit" looks
weird, I also changed the style of these to "property()".

- I moved the Semantics id generator closer to where it's used, in
SemanticsModifierCore. I made it internal and an AtomicInt.
(Note that integer ids are heavily used in the Android
AccessibilityNodeInfo APIs so I can't simply remove them entirely.)

- I deleted dead code. Some examples include SemanticsHintOverrides,
a public API not connected to anything, and SemanticsPropertyKey
merge() open method which is never called. (In both cases I have
a different plan in mind for accessibility.)

Fixes: 145951226
Fixes: 145955412
Test: existing tests
Relnote: "Single-value semantics properties now use a calling style.
For example, 'semantics { hidden = true }' is now written as:
'semantics { hidden() }'."

Hi, thank you for reporting this issue. It is very unfortunate that this was not caught when we were trying to make a performance improvement and definitely not something devs should need to guard against. We are working on a bugfix release shortly.

Thanks a lot for getting back to me here. So it was a simple mistake after all, that is great to hear. I was just a bit concerned that this has setting a different precedent than what we typically expect with these apis. Since it's a bug I'm happy to hear that. Looking forward to the fix, thank you again!
