Hi! What do you do when you need to use colors inside a mapper, which is injected to your viewModel via DI? I’ll provide details in a thread below

Have you experienced Compose memory leaks? When adding google maps (which had/maybe still has memory leaks in the view system), it will leak memory which adds up and app will be killed by system. I have found https://android-review.googlesource.com/c/platform/frameworks/support/+/1826246 which might be fixing the issue. How do I find out when this will be released?

When using a

Box

that renders an arc with

Canvas

and a centered `Text`; why is the

Box

sizing wrong if contentAlignment is set to center? 🧵

when writing a

@Preview

composable, is there any way to get it to render a piece of UI with focus applied? I tried adding a

FocusRequester

and using a

LaunchedEffect

in the preview to request focus, but that doesn’t seem to work in the preview.

Hi Team, is it good to have multiple NavHost in one project

I heard that having R8 disabled will have a significant impact on Compose Render time. I was just reading this article about it. I was just wondering if Google recommends to enable R8 for compose?

✨ Animation API As per my understanding,

MutableTransitionState

(MTS) with

updateTransition

is only useful if we want to update the state within the composable. If we simply want to access the

MTS#currentState

,

MTS#targetState

and

MTS#isIdle

, we can use

Transition#currentState

,

Transition#targetState

and

Transition#isRunning

respectively. Please correct me if am wrong.

Hi guys, I’ve just started experimenting with Compose. Any ideas how to go about implementing something like iOS calendar with Compose (the timeline on the left, and events constrained to specific times)? ConstraintLayout, custom view, something else? (picture in thread)

I am trying to make a square card with items horizontally aligned in center, thats size is dynamic, base on the content. In my case, the height is always the leading(higher) value. It is not possible to measure twice, so I am trying to use the

IntrinsicSize

and

layout.measure

, but I cannot make it work. I managed to have a square card, but items are not in center. More in thread 👇

Question about

TextField

value and State. Can someone explain why, given the following composable:

var text by remember { mutableStateOf("") }
TextField(
    value = text,
    onValueChange = { newText ->
        Log.d("TEXTFIELD", "NewText: $newText")
        val editedText = newText.replace(Regex("\\D"), "")
        if (editedText.startsWith("1"))
            text = editedText
    }
)

If I type the number 5 into the text field four times, the result I see in LogCat is:

D/TEXTFIELD: NewText: 5
D/TEXTFIELD: NewText: 5
D/TEXTFIELD: NewText: 55
D/TEXTFIELD: NewText: 5

I’m stumped?

So Kotlin 1.5.31 isn't compatible?

Hi! 👋 Testing + AnimatedNavController I want to test a composable that has its own navigation. I pass in an instance of

TestNavHostController

as

NavHostController

parameter (defaults to

rememberAnimatedNavController

) but get an exception when the building the navgraph:

androidx.navigation.testing.TestNavigatorProvider$navigator$1 cannot be cast to com.google.accompanist.navigation.animation.AnimatedComposeNavigator
  at com.google.accompanist.navigation.animation.NavGraphBuilderKt.composable(NavGraphBuilder.kt:124)

Doesnt the accompanist nav animation lib support testing yet? (code in 🧵)

Hi, I integrate Google Map in one of Compose Screen but it's freeze for a bit of time, Is there any solution to prevent blocking the UI ? the freezing is because I use :

val mapView = rememberMapViewWithLifecycle()

Hi. Is there alternative for BulletSpan in Compose? In SpanStyle, it seems, there is not parameter for this

Getting this build error: `e: This version (1.0.2) of the Compose Compiler requires Kotlin version 1.5.21 but you appear to be using Kotlin version 1.5.30 which is not known to be compatible. Please fix your configuration (or

suppressKotlinVersionCompatibilityCheck

but don't say I didn't warn you!).` while my kotlin version is currently at 1.5.21, with this in my root gradle file:

classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.21"

Hi, I have difficulties with

ModalBottomSheetLayout

. Clicking on

Scrim

area above the modal doesn't close it. According to a documentation a click should close it. Can you please confirm this is a bug?

Is it possible to somehow change the minimum tab size of ScrollableTabRow which is currently linked to a private val called

ScrollableTabRowMinimumTabWidth

? Or do I have to copy the full implementation to make this change?

[SOLVED] I try to share a FAB between the content of multiple Tab items but I'm struggling. Can someone help?

Why passing

content: @Composable ColumnScope.() -> Unit

in

content: @Composable () -> Unit

and invoking it in

AnimatedVisibility(...) {
   content()
}

Cancels the ColumnScope?

there are a way to "clear" a rememberLazyListState(). I want clear the state only when i perform an action, the rest of the time i want to hold the state.

think missing something. AS can't render Compose preview with CameraX Preview.🧵

Hello everyone 👋 I think I've spent ~30 hours now over 3 days trying to figure out what is going on with this insanely weird compose issue. I was hoping I could share the nightmare I've found myself in and see if anyone would mind playing rubber duck here to help me get more ideas on how to tackle the problem. At a high level, here's what's going on. I work in 3 different android projects. Project 1 and Project 2 are working properly with compose and I'm migrating more and more of UI to compose and everything works flawlessly. I just added the exact same compose dependencies to project 3 and found that what I am seeing in Compose Preview is broken when I run the code in an emulator or real device. I stashed all my compose work and just made a simple screen that has a Column with verticalScroll that just loops 40 times and renders a Text component. When I deploy this code, the column DOES NOT scroll. I take this EXACT same code and copy it to Project 1 and 2, deploy, and I'm able to scroll the Column. Other things don't work as well such as clipping a Custom Shape etc but I'm positive all the issues are related. So I am just focusing on getting the simple Column with vertical scrolling to work. What. The. $@#!. Right? I'll post some of my notes/findings/additional info in thread for anyone curious or who may have insight. I sincerely apologize for the long message in this channel and really have tried avoiding bothering anyone with this as I'm trying to figure it out but I really am losing my mind at this point...

Should it be possible to use the interop layer of compose to use a ComposeView in ReactNative?

In LazyColumn, is there a simple way to scroll to an item based on the key? Or do I have to keep a list of indices somewhere and use that to scroll to specific items?

How to create button without rounded corners (can it be done without specifying border with 0.dp width)?

Something really unusual happened to me and I don't know where to start looking

My drawable resources are not displaying in original color in composable view. Color change to black (maybe due to app theme). How do I retain original view for drawable? Anything related to composition local?

I don’t quite understand relations between State<T> and Transition<T> and how to make a “composable” animations. Let’s say I have this simple data class:

data class ShapeStroke(val width: Dp, val color: Color)

I want to write a function

fun <S> Transition<S>.animateShapeStroke() : State<ShapeStroke>

so that it would just add child animations for width and color and return

State<ShapeStroke>

instance. What’s proper way to do this?

Hi guys 👩‍💻 looking for some testing advices i want to create my first

androidTest

and im having some problems trying to mock the ViewController of my view, maybe im doing something working but i would like to test only the view without the view controller (i already have the Unit test for my view controller) how would you do it using hilt and compose-navigation (

HiltAndroidTest

)
