I’m seeing some interesting behavior with

remember

in a few of our screens. Essentially I have multiple “Screen” level composables which store a remembered value in a val and the val has the same name in all of those composables. This results in the remembered value actually being shared across these screens as I navigate between them. Is this expected? 🧵

Hi guys, I'm using a compose TextField I want to paste text at the beginning of a word But when i long press cursor, (or tap the blob under the cursor) the word after cursor is selected instead of exposing the context menu how do i do?

Hi, is there any references to implement dynamic locale app language, like whatsapp do. (It can use the system anguage but also we can change it too, to custom language, (not following the system language))

This question could go in #android or here, but I’m looking for resolutions specific to a compose only app so I’ll post here. We’re seeing an issue in our app around Deeplink navigation. We’ve set up our app to be opened by links to our web app on Android. We decided we wanted the launchMode of our activity to be

singleTask

so that our app does not have multiple instances running in different tasks. When we open a task we are seeing two instances of our Activity being created which has lead to some issues. More in 🧵

There was an video about showing a button to scroll to top when you reach the bottom of the list, i'm having hard time finding which video this is. Anyone has any clue? It was one of the performance improvement videos

So i'm trying to implement a search bar using a custom wrapper for BottomSheetScaffold along with my own custom search bar state (similar to SnackbarData and SnackbarHostState). I've got it all working, but the keyboard is covering up my confirm button. Is there a way at the composable level to tell the composable to resize when the keyboard is shown? I really don't want to have to do this at the activity level, as we don't necessarily always want that behavior.

I have nested graphs for navigation in jetpack cpmpose, I am getting this error:

java.lang.IllegalArgumentException: Navigation destination that matches request NavDeepLinkRequest{ uri=android-app://androidx.navigation/appointments } cannot be found in the navigation graph NavGraph(0x7c328b99) route=authGraph startDestination={Destination(0xa0a5cfdc) route=Login}

ANY idea how to solve it, since I am not opening any link just navigating between the login and entering the main view on success

Is there anyway to force recomposition in tests? I want to ensure something is executed as a

LaunchedEffect

but I can't find a way to emphasise that with a test.

Hi, I am using MutableStateFlow in my jetpack compose. Like below

val isBluetoothEnabled = MutableStateFlow(false)

whenever I tried to use the value of variable like this

.value

i.e.

isBluetoothEnabled.value

. So I am trying to use delegate property to avoid using

.value

val isBluetoothEnabled by MutableStateFlow(false)

but I am getting weird error

Type 'MutableStateFlow<TypeVariable(T)>' has no method 'getValue(PairViewModel, KProperty<*>)' and thus it cannot serve as a delegate

Hello! I have a button and a text right to the button in a row. How can I make text flow under the button but only for those lines that overflow. First lines with sum height as button height must stay right to the button.

Are there any downsides/ performance impacts when using Generic composable function? e.g

@Composable
fun <T> CardList(
    items: List<T>,
) {
    // TODO Draw your list here.
}

Im working with a Canvas, but once it drawn, it redraws every composition, causing non desirable effects. Anyone know how to avoid this kind of situation?

Is there anything like

onPageChangedListener()

in

HorizontalPager

Accompanist? I want to trigger some function when the user swiping to another page.

I’m trying to have a dynamic modal bottom sheet, based on the user selected

var selectedUser: String? by remember {
   mutableStateOf(null)
}

ModalBottomSheetLayout(
    sheetState = sheetState,
    sheetContent = {
        selectedUser?.let {
            UserDetail(
                id = selectedUser, 
                onCloseClick = {
                    coroutineScope.launch {
                        sheetState.hide()
                        selectedUser = null
                    }
                }
            )
        } ?: Box(modifier = Modifier.fillMaxSize())
    },
) { 
... 
    coroutineScope.launch {
        selectedUser = "userid"
        sheetState.show()
    }
}

I added the default

Box

because otherwise there is an exception

java.lang.IllegalArgumentException: The initial value must have an associated anchor.

so my questions is do you guys think this is the right way of making a dynamic modal bottom sheet or is there a better way without going through the Box? (I know I could use scaffold but I don’t want interaction with the main screen)

Is Navigation Animation from Accompanist going to be merged to Compose any time soon?

Hello! I have an advice regarding compose navigation and bottom nav bar. For example, I have two main roots (A, B) in the bottom nav, and based on the documentation I navigate between them using the saveState and restoreState (https://developer.android.com/jetpack/compose/navigation#bottom-nav). Each main root screen has their own Viewmodel, which are saved and restored each time I navigate A -> B and B -> A. I would like to call a refreshState every time I come back to A (the fun would simply update the VM UI state and re fetch data for some properties). I have found some workarounds but I do not like them a lot. Are there any specific recommendations / suggestions for these cases? I could probably avoid the saveState but I do not want to recreate the VM each time I navigate back to the viewmodel A. Thanks!

Hi everyone, does Compose has anything to offer for testing hybrid layouts inside a Fragment? Current test is written in

FragmentScenario

so there is no concept of an

Activity

so I guess

createAndroidComposeRule

won’t be useful as it only takes activity.

Hi, How to show this default full size text field on the landscape mode in compose. In xml by default it opens this view when I click edittext on landscape mode.

so I have a LazyColumn, with

items

, and when something happens to one of the items’ onClick (defined in itemContent), I want the

items

value to change, the list to be shuffled, re-ordered, etc.. how can I do that ?

Hi ! I'm trying to define a squared component. So that the component's size is always a square based on the minimum of its {maxWidth, maxHeight} constraints, and keeping its original location in the parent composable. So I've tried to define a modifier called

clipAsMinimumSquare

, but in the preview it seems that the composable to which I'm calling this modifier is still a rectangle, whereas its content is a square. As you can see from the code, I'm calling

layout

on the

Modifier

, but it seems that I've not defined it well.

why does

animateColorAsState

break my

@Preview

in Flamingo?

I'm using the 1.1.0-alpha02 version of the material 3 library. I want to use the swipeable modifier but it's marked as internal, what can I do? I'd like to be able to use it now rather than wait an unknown amount of time

We’re having a style discussion on my team and I thought I’d crowd source it. We have a composable which is conditionally shown. You can assume this isn’t for a library with a large user base and we don’t have any need to do animation or transitions in this case. Which of these options would you prefer: • A. Encapsulate the conditional display within the composable itself so all consumers get that logic included • B. All consumers should conditionally show/hide the composable by not calling it when they don’t need it • C. Make visibility a parameter for the composable as a compromise between A and B. • D. It depends and none of these are more “right” than the other. See example code in 🧵
