ContentAlreadySetError cc.: @Jelle Fresen [G] Can you elaborate a little bit on that? Why is that always bad? We have a test that perfectly worked pre 1.2.0-rc01 and now breaks with this exception. (more details in the thread) Whats the alternative?

Is it possible to change the background color of a

DropdownMenu

? It seems to inherit it from the theme internally. Using

Modifier.background

doesnt work in the sense that Im able to see parts of the inherited background as well.

What's the best option to run a modifier only if a value is not null? We've created this:

inline fun Modifier.optional(
    block: Modifier.() -> Modifier?
) = block() ?: this

And we use it this way:

.optional {
    frameColor?.let {
        border(4.dp, it, CircleShape)
    }
}

It there a better way to do this? 🤔

Is live edit working with multimodule with KMP?

I have an app with three distinct graphs, each with separate needs for a

Scaffold

. • Graph1 has no scaffold • Graph2 has typical bottom scaffold • Graph3 has top and bottom scaffolds, but only with

Graph3

routes I am wondering how to build this. Should I have multiple

Scaffold

and

NavHost

or instead use just one

NavHost

and one

Scaffold

, switching out the

Scaffold

content based on current Graph? Thank you 🙂

Hi folks, LazyVerticalGrid in

1.2.0-beta02

crashes (only on OPPO and Realme devices) when calculating child constraints.

crossAxisSize

has a negative value. Does anyone experience the same crash?

We have some problems with the statusbarpadding appearing to be 0 only on some devices… so far only observed on Android 10 (Pixel XL Emulator and Xiaomi real device) but not on higher APIs … has anybody come across this / is this a known issue?

I'm looking for a component that could work for a 'popup' effect on my screen. Something where it could appear to be 'on top of' other screen components (raised z axis) but having some trouble implementing. At first I thought a Box would be good, but when that is embedded in a row and column it will resize and move other components around. I want it to appear above these components instead - is there a way to do that with a box or should I be using a different component?

Has anyone done a PDF Viewer type of component in Compose? Would people generally just wrap existing libraries that were build for the old view system? Looking for the correct/good way of doing this, in a full compose app (don’t mind wrapping an android view tho if that’s what we have to do).

Does compose

1.2.0-*

needs

Android32

as targetSdk? Happening when am using latest accompanist version 🤔

😬 could be a stupid question: If a library is transitively using a latest alpha version of compose, (eg,

1.2.0-alpha01

) and the app using latest stable version (eg.

1.1.1

), which version will gradle pick? (i hope its the former -

1.2.0-alpha01

) In that case, if there’s a breaking API change in the latest version, how that’s managed by gradle? Would that fail the build? or does compose compiler will do some magic? 👀 Would this version conflict can cause an error like this?

question for those who are using one

NavHost

, one

Scaffold

and

BottomNavigation

at the root level, with many nested screens & Composables under that: is there a recommended way to show and hide the

BottomNavigation

? I have a nested

LazyColumn

which I’d like to use to trigger showing/hiding of that

BottomNavigation

when I scroll up/down. this is fairly simple when the

BottomNavigation

is “closer” to the Composable triggering it, but when it’s deeply nested I wonder what the best solution is? do I simply pass a lambda like

toggleBottomNavigationVisibility

all the way from the top level where the

Scaffold

is, through many Composables, down into my deeply nested one? this would work but I would like to know if there’s a better way and my brain isn’t seeing it 😄

I am trying to get some content align with in a specific way and wanted some thoughts on how you would build this. Weight of 1 seems to fill the full width so I am nesting that and assumed I could put something to the right of it but its off the screen 🧵

Hello, how are you guys saving and restoring the text states for your

TextFields

?

I drew a rectangle where i wanted only top left and bottom left rounded. But when you zoom in the corners look bad. Is it something to do with anti-aliasing. I draw rect with path. https://gist.github.com/raghunandankavi2010/aecb872b021dc42a9568d76c023629ca. How can i make this rounded corner smooth?. Emulator screen shot added.

How do I call methods of view in androidView?

AndroidView(
                factory = {
                    CropImageView(it).apply {
                        setCenterMoveEnabled(true)
                        setSnapRadius(16f)
                        setBackgroundColor(Color.Black.toArgb())
                        with(density) {
                            layoutParams = ViewGroup.LayoutParams(maxWidth.roundToPx(), maxHeight.roundToPx())
                        }
                    }
                },
                update = { cropView ->
                    // how to call cropView.rotateImage(90)                                    }
            )

I am having some issues with LazyListState and the initial scroll position. In some cases I am trying to set the position to the last item in the list. This works for smaller lists, say 20 items. But when I get to larger lists I seem to end up in the middle of the list. Code in reply

Wouldnt it be beneficial to have navigation logic outside of compose? Ive seen quite a few navigation libraries where a navigator sits at the root, and the different screen composables of the app delegate onViewDetails, etc, to the navigator which manipulates the backstack to show the appropiate screen. 🧵

Is there a chance Pager loads pages without being attached ? I have a very simple layout with custom measurements/placements. That layout is used on every Pager page. I had no problem for months, but the moment I updated Compose (1.05 -> 1.2.0-rc1) and accompanis (0.18 -> 0.24.11-rc) I started seeing :

Fatal Exception: java.lang.IllegalStateException: LayoutCoordinates androidx.compose.ui.node.InnerPlaceable@50d1d48 is not attached!

On firebase, without code changes. Worst of all is that It cant even bee reproduced reliable

If I have the below code, Is there a way to clip B to only where A has content (not clip to bounds, but actually clip B to where A has drawn)?

Box {
  A()
  B()
}

It’s fine if the API here changes. The only way I can think to do this would be to somehow render A and B to `ImageBitmap`s and then draw them in a

Canvas

with a

BlendMode

. However the only way that I can think to get A or B to

ImageBitmap

would be with

ImageComposeScene

which seems like a really bad idea.

Hello, I am implementing smooth scroll to top functionality, but the call to scroll to the top comes from outside compose land. Is this a proper way to use a LaunchedEffect?

if (viewModel.state.scrollToTop) {
    LaunchedEffect(viewModel.state.scrollToTop) {
        scrollState.animateScrollTo(0)
        viewModel.updateScrollToTop(false)
    }
  }

When Compose 1.2.0 reaches stable , will it target 1.6.21 or 1.7.0 of the Kotlin Compiler

Maybe I need more sleep... but how do I make sure that I use the default capitalization EXCEPT when I declare the type to be a NAME?

KeyboardOptions.Default.copy(
    capitalization = when (textFieldType) {
        MyCustomInputFieldType.EMAIL -> "How do I use the default here?"
        MyCustomInputFieldType.NAME -> KeyboardCapitalization.Sentences
        MyCustomInputFieldType.NUMBER -> "and here?"
    }

😛arty-parrot: Compose Version 1.2.0-rc02 out today! • Nothing substantial! Hooray getting close to stable material3 Version 1.0.0-alpha13 out today! • Supports maintaining the top app bar position on configuration change • Fix Material outline text field label measurement (although I think this was in the previous release)

Hi everyone, I was currently working on my apps with colors and themes using compose, does anyone have an idea how to change the cursor color from this very bright pink to something else

I have an ExposedDropDownMenu that is extremely laggy delayed when opening. It takes like a good 4 seconds (and yes this happens in release builds too). I have a bunch of items (it's a country picker actually). My idea was "I know lets make it Lazy" but that leads to a crash. Any ideas from anyone?

Hi! I am trying to implement swipeable buttons like below...like you can swipe that blue highlighted box to select a different setting. However, I am not yet fully successful in doing so.. please share if you have any helpful ideas or links. Thanks!

In which compose version, foundation introduced the

WindowInsets

class ? 🤔
