Is there a way in which I can automate the packaging of a Desktop Compose app using a CI agent? I've been trying to use a Gitlab-ci Runner. My goal is to automatically make an msi when I push to a certain branch. As far as I understand, one can't use

packageMsi

from a linux context, so there goes the docker runner. I've been trying to get it done with a windows-docker executor, but that doesn't seem to be able to reach gradle, and I don't think a win-gradle image exists on Docker Hub (at least I couldn't find one). I'm sorry if this has been asked before.

Hi, how wrong is it to rely on

NavDestination.createRoute

to use

Parcelable

with Navigation Component when using the new Route System (String based) for Fragments/Composables? I understand that it is an internal API, and I’m not supposed to use it, so I’m coming here to find a better option before making a final decision (see the thread for more details). I appreciate any help you can provide.

What's the best way to achieve this layout? I'm currently offsetting my image but that causes spacing issues so is there a better way?

Hi all, I have this issue with StateFlow: MainActivity:

...
    val loading = binding.loading
    loading.setContent {
        LoadingSpinner()
    }
...

@Preview
@Composable
fun LoadingSpinner() {
    if (viewModel.loadingState.value) {
        CircularProgressIndicator()
    }
}

in my viewmodel:

_loadingState.value = true
viewModelScope.launch {
    doSomeLongTask()
    _loadingState.value = false //or calling this at some later point
}

LoadingSpinner() is updated correctly when value == true, but then when I set it to false, LoadingSpinner does not get updated and so stays on screen. Any help appreciated!

compose 1.0.1 finally supports kotlin 1.5.21 https://developer.android.com/jetpack/androidx/releases/compose#1.0.1

Alright, so this was definitely working yesterday and now it's not today and I've spent 3 hours trying to figure out why my composable isn't recomposing when the list contents change. Code in thread.

Is there a way to override `DropdownMenuItem`’s click indication color outside of the material theme? I’ve tried this to no success

DropdownMenuItem(onClick = { /*TODO*/ }, 
                 modifier = Modifier
                .indication(
                            interactionSource = remember { MutableInteractionSource() } , 
                            rememberRipple(color = Color.Red))) {
   Text("Some Menu Item")
}

Is anyone else facing compiler issues in projects with multi-modules?

Caused by: org.jetbrains.kotlin.codegen.CompilationException: Back-end (JVM) Internal error: Couldn't inline method call 'Row$default' into
@androidx.compose.runtime.Composable public fun Error(): kotlin.Unit

Possible related issue: https://issuetracker.google.com/issues/189138228 Working with Compose in a small sandbox app works fine but as soon as I try to integrate it into our main app I get the above error when using any Composable that’s an inline function (

Row

 and 

Column

 for example) We started playing with Compose during the first RC and have seen it since then and continue to see it in todays 1.0.1 release

I'm just trying to pin a Crossfade with a button at the bottom of the screen with weight 1f. I can pin the button at the bottom of the screen, but once I wrap it with Crossfade it pins the button at the top of the screen. Code in thread.

Is this not required for Compose 1.0 anymore? Seems to build just fine without it.

composeOptions {
    kotlinCompilerExtensionVersion "…"
  }

Hello! How can i adjust compose view to keyboard show/hide?

Would it make sense to create (and dispose with

DisposableEffect

) a

Composition

in the

skippableUpdate

parameter of

ComposeNode

?

Row() {
    Canvas(modifier = Modifier.size(20.dp)) {
        drawCircle(
            color = Color.Gray,
            center = Offset(x = 10f, y = 10f),
            radius = size.minDimension / 4,
        )
    }
    Canvas(modifier = Modifier.size(20.dp)) {
        drawCircle(
            color = Color.Gray,
            center = Offset(x = 10f, y = 10f),
            radius = size.minDimension / 4,
        )
    }
}

How Can I update color of specific circle based on index number?

What is NavigationRail?

Anyone else do a bunch of updates today (latest alpha androidx everything, compose 1.0.1 or 1.1.0-alpha01 and kotlin 1.5.21) and hilt started breaking? Been trying to diagnose this now for a few hours. Throwing in the towel for now and reverting. https://github.com/google/dagger/issues/2800

Hi there, I'm using Hilt to inject dependencies. I was wondering if it's possible to instanciate an object which contains depencies (injected with Hilt) in a Composable ?

What would be a good approach to building a “modular” composable. e.g. something that has a header,content,footer section. Would you you write it like fun Container(header: () -> Composable, content: () -> Composable, footer: () -> Composable): Composable ?

Hi! I’m using navigation-compose alpha06 and having crashes whenever I tried to popBackStack from a nested navigation. Does anyone having the same issue? Sample code in 🧵

what is the best way to expose state from

ViewModel

? am using compose’s

MutableState

but I see a lot of examples with

Flow

but I don’t see any need for using

Flow

to expose state in pure compose app. is

Flow

used in app in transition from

View

to

Compose

to bridge the gap and use some of the existing code or

Flow

is for some reason more favourable than

MutableState

?

Is it possible to make extra padding for content in Scaffold if FAB is showing? Or may be there are more correct way to handle FAB overlaping?

In Compose do you typically inline define menu items using maybe something like listOf(“menu item 1”, “menu item 2" … etc) or would you load menu items from a menu XML like you used to?

Hello! I 've a compose test on here: https://github.com/alorma/Coupons but trying to run it it always says:

Let's say you have some logic in your ViewModel that should trigger a snackbar in your UI/Composable. How do you send that event? In XML times I used an event channel but this doesn't seem to work well with Compose since 2 times the same snackbar text in a row gets ignored by the

mutableStateOf

holder.

Is there a way to go through one measure pass in a custom layout and then before laying out children, re-measure with a different set of constraints calculated from the first measurement? Essentially I think I'm trying to use

Intrinsics

in a custom layout because I want all my children to be the height of the largest child. Is there an easier way to solve this? I could potentially just use out of the box Layouts + Intrinsics but I'd like to try and solve it with a custom layout.

How to make loading new chunk of items in LazyColumn when user scroll to last item?

Hi, I am getting the dreaded

java.lang.Class<ViewModel> has no zero argument constructor

error when using the

hiltViewModel

function. Being stuck on this for over two hours now. I have added all the required libs and annotations but the error won’t go. Any help will be appreciated.

This is how I send a result from an edit screen back to the parent screen on the backstack. But I would like to receive this event only once (like it is the case for the old fragment result API). Is there a way to do that?

composable(TodoScreen.TodoList.name) { navBackStackEntry ->
            TodoListScreen(
                [...]
                addEditResult = navBackStackEntry.savedStateHandle.get<Int>(KEY_ADD_EDIT_RESULT)
            )
        }

As far as I see, I will always receive this result on every recomposition (like when the screen is rotated) causing to show feedback snackbars again.

Does

LazyColumn

not yet keep scroll position after config changes or is my setup just wrong?
