Hey guys, is it possible to 'draw' a composeable to a ImageBitmap or to make some kind of screenshot of a specific composable? (during runtime not testing) Asking aspecialy for Compose for Desktop but I would say this is a general Compose topic

This way of observing a SharedFlow (repeat=0) seems to work but it looks suspicious, especially because of

LaunchedEffect(true)

. There's probably some other

Effect

that I should use, right?

val pagerState = rememberPagerState(pageCount = pages.size)

LaunchedEffect(true) {
    //SharedFlow 
    pageChangeFlow.collect { 
        pagerState.animateScrollToPage(it) 
    }
}

HorizontalPager(state = pagerState)

I’ve got some data classes loaded from a database, which make their way to my compose function, via StateIn in a ViewModel. I wanted to adjust the equality predicate for these objects, to be based on ID, rather than comparing all fields. Since making this change, I’ve noticed that my layout isn’t recomposed when the database emits an updated model whose ID has not changed.

I'm having an issue with a preview not rendering, I have a data class that stores a refernce to a drawable, as part of the preview I'm creating some dummy data and referencing real drawables, but the preview complains that the drawables don't exist, see :thread-please:

Hey! Wanted to implement a scrollable list that isn’t clickable when some conditions are met (eg. a snackbar is displayed). I came up with that idea:

Column(modifier = Modifier.pointerInteropFilter {
    when (it.action) {
        ACTION_DOWN -> {
            true
        }
        else -> {
            false
        }
    }
}
... some other code
)

But sadly that code blocks all scroll interactions. How can I intercept clicks to my buttons on a scrollable column without disabling the scroll?

Is there a known bug about LazyRow items overlapping when scrolled fast?

val getContent = registerForActivityResult(ActivityResultContracts.GetContent()) {
    viewModel.imageUriState.value = it
    // Handle the returned Uri
}

if (viewModel.imageUriState.value != null) {

    Log.d(TAG, "${viewModel.imageUriState.value}")
}
getContent.launch("image/*")

Hi, I got the Uri of the photo from the user's album using registerForActivityResult, how can I convert the Uri to ImageBitmap and store it in my room? i've searched a lot from StackOverflow, but there doesn't seem to be a very standard answer

Can someone explain to me why

BocWithConstraints

skips a Frame before rendering its child nodes? [wrong call]

Hi there. Today I managed to catch this crash in 1.0.0-beta03. Is it a known issue? Reproducible only on Pixel 2 XL, 11.0.

What is the icons package for jetpack compose? I have implementation “androidx.compose.material:material:1.0.0-beta03” but I cant find icons like import androidx.compose.material.icons.filled.NavigateBefore

Hi there. Lint is showing me "Conflicting on color for a given background" when creating a DarkColorPallete. Here is a capture. Am I missing something?

Is it possible to customise the equality predicate used by Compose to determine whether recomposition is required (i.e. observe particular fields of an object)?

Any way to show a bottom sheet dialog without adding

ModalBottomSheetLayout

as a root component to the app? My use case: I have an existing app with bottom navigation implemented as a fragment, and I will slowly migrate each tab (each its own fragment) to jetpack compose. How would I render a bottom sheet on top of all that UI? There doesn't seem to be an equivalent to

AlertDialog

but for bottom sheets

how can I listen for route changes in compose navigation and check for a specific route ?

can you point me to idiomatic

Compose

MVI

example?

How to implment button like this with Compose?

Finally achieved parallax effect with LazyList

Hey, are there any plan to have transform(matrix:Matrix, path:Path) API on new compose path package ?

How we should use

Modifier

that is passed to compose function. What the idea there? Should it be passed to first composable function, or to most inner function? Should we treat it like

layoutparams

, so it’s for the most outer composable? Is it okay to pass multiple

Modifiers

to different composables?

Hello, everyone! 👋 Do Jetpack Navigation Compose have support for Dynamic Feature Modules? At the moment I have a Navigation Graph similar to:

NavHost(navController = navController, startDestination = startDestination) {

    composable(Destinations.Home) {
        Home()
    }

    composable(Destination.TaskDetail) { 
        TaskDetailSection()
    }

    composable(Destination.About) {
        About()
    }
}

But I don’t see how I can make my graph call a compose from a DFM ou how could the DFM register on this graph. Thanks a lot in advance! ❤️

I have text in a textfield, but when I use IMEAction next to go to this textfield, the cursor is in front of the text. Does someone know which property I can use to change it.

Has anyone tried to show some compose UI for when the app was moved to the background? The use case is that we need to have a privacy screen that will be shown in the app switcher whenever the user has closed the app. I was able to achieve a UI change by updating a

mutableStateOf

when the activity hit

onPause

but then in the app switcher it still showed the old UI. I also was trying to use the Lifecycle architecture component to update the state but that didn’t work either. Is this something that can be achieved with Compose? The current code is in the thread.

I tried to achieve an online green dot before text using drawWithContent but the text/content is overlapping . Can anyone guide me to solve this issue?

Text(
    text = "Online",
    style = MaterialTheme.typography.subtitle2,
    maxLines = 1,
    color = MaterialTheme.colors.onSurface,
    modifier = Modifier
        .drawWithContent {
            drawCircle(color = green, radius = 25f)
            drawContent()
        }
        .constrainAs(online) {
            start.linkTo(name.start)
            top.linkTo(verifiedLogo.bottom, 10.dp)
        }

)

Is there a new way to create Scrollbars?

VerticalScrollbar

seems no longer to exist..?

Does jetpack compose have an image cropper?

I have seen some Animation examples online, but not able to use

onActive{}

. • Does it still exist, or does it have a different name/approach now? Currently using compose version

1.0.0-beta3

, i did import

runtime

,

livedata

and

rxjava2

but still cant see these methods. • I would like the animation to start as soon as its rendered. For this I would use

animateFloatAsState

for this together with

onActive{}

. I guess the is how we handle animation.

Hi Devs, I need help 😩, please how can I achieve this design ?

Got this error during upgrade to kotlin 1.4.32

e: This version (1.0.0-alpha13) of the Compose Compiler requires Kotlin version 1.4.31 but you appear to be using Kotlin version 1.4.32 which is not known to be compatible.  Please fix your configuration (or `suppressKotlinVersionCompatibilityCheck` but don't say I didn't warn you!).

I knew about this (that this needs to be suppressed if one wants to upgrade kotlin), but the curious thing is the “1.0.0-alpha13” version of compose compiler part. Why alpha13 if I’m using beta03?
