Ok I might be too tired to work on this at 11pm instead of going to sleep, but what is wrong with this that the load of the value doesn’t trigger recomposition?

@Composable
fun ProfileScreen(userUid: String) {

    val userRepository = UserRepository()
    val user = mutableStateOf<User?>(null)

    launchInComposition {
        user.value = userRepository.get(userUid)
        Log.d(TAG, "url = ${user.value?.profileUrl}")
    }

    user.value?.profileUrl?.let { CoilImage(data = it) } ?: Text("No Image!")
}

Is there an opt-in or field that I'm missing for TextField's to accept hardware keyboard inputs (e.g keyboard using emulator)?

Is there a way to add update animations in

AdapterList

when items are added/removed/moved I have a simple tasks list function where checked items move to the bottom. However, it happens almost instantly without any delay at all.

@Composable
fun TaskList(taskHandler: TaskHandler) {
    AdapterList(data = taskHandler.list.sortedBy { it.isChecked }) {
        TaskItem(task = it, taskHandler = taskHandler)
    }
}

@Devesh Sanghvi what do you mean by BottomDrawableLayout? Is it a composable in Jetpack Compose? How do you create it? Could you please share some code?

Are there any nice samples out there showing how to combine Kotlin's Flow and Composables? I.e. what's best practice on how to render data from a Flow in a compose-friendly way

The DI should be decoupled from it all imo if possible

Posting this here because assume you’ll all be on the canary version of Android Studio (let me know if better place to post it), I’m having trouble getting my Android Emulator to work. I’ve reset all the AVD devices and created a new one but it just launches with a black screen.

Where can i found jetpack compose compiler plugin source code?

Can I get the height of a child composable function if I pass it as a parameter? example:

fun CustomBottomDrawerLayout(
        drawerState: DrawerState,
        onStateChange: (DrawerState) -> Unit,
        gesturesEnabled: Boolean = true,
        drawerShape: Shape = MaterialTheme.shapes.large,
        drawerElevation: Dp = DrawerConstants.DefaultElevation,
        drawerContent: @Composable() () -> Unit,
        bodyContent: @Composable() () -> Unit
) {

Can I calculate the height of the drawerContent?

WithConstraints

might get you there I would think

Created a swipeToDelete modifier with

draggable

Hello, can I put the code in a class? something like that:

abstract class BaseState(
    private val textState: String
) {

    @Composable
    fun render() {
        Text(
            modifier = Modifier.padding(8.dp),
            text = textState
        )
        renderChild()
    }

    @Composable
    protected abstract fun renderChild()
}

I get an error: e: java.lang.IllegalStateException: Cannot find the Composer class

I'm clearly missing something about scaling canvases - I have a circle who's center offset is the same as its radius, so it should touch the side of the canvas, and indeed it does when the scale is 1f.

@Composable
private fun QuickView() {
  Box(Modifier.wrapContentSize(), border = Border(2.dp, Color.Black)) {
    Canvas(modifier = Modifier.size(200.dp, 200.dp)) {
      val scale = 1f
      scale(scale) {
        drawCircle(Color.Green, 100f, Offset(100f, 100f))
      }
    }
  }

Putting the scale at 0.5f however reduces the radius as expected, but increases the center offset.

I understand correctly that it is impossible to implement a state machine here?

So leaning to yes for your question :)

Unrelated text input question: the kdoc for text fields say that

onValueChanged

should not be used to change the value of the text field to anything other than what the IME sent. This implies it shouldn't be used to implement something like

InputFilter

for eg phone numbers. Is this a temporary limitation, or is there a plan to address this use case another way?

Is there a way to tell an Image to be round?

Wow devs will have so much to unlearn with Compose! The fact that my ‘root layout’ is not in

.fillMaxSize()

by default is giving me headaches. I’m so used to create a layout and it being set to

match_parent

/

match_parent

, it is mind blowing! This piece of gold helps me a lot:

fun <http://Modifier.help|Modifier.help>() = drawBackground(Color.Red)

I’m trying to give Compose a try in my current project and I’m facing a problem. I’m trying to use

0.1.0-dev14

version, because in the project I’m using SQLDelight also which is not ready for Kotlin 1.4. Here is the log I’m getting when trying to compile:

I don’t understand what require 1.4 version

Hi all, I'm doing a spike on integrating

Compose

into an existing project. Trying to answer some questions like is it possible to create a new Compose-based

Fragment

in a multi-tab

Activity

and in general how such integration would look like. I notice most of the Jetpack examples right now are Fragment-free so wondering if that is even doable. If anyone has gone through a similar journey can you please give me some pointers? Thanks

It seems like if I start an external activity (like the

ACTION_VIEW

Intent with a Uri) and then press back to come back to my compose-based app, the Composable parts aren't recomposed. The containing activity gets onStart and onResume called as expected. Does that mean I should be creating my app in onStart instead of onCreate? Or is there a way to detect this from within composables? I'm expecting a state change upon returning to the app, based on something that happens in the activity's onStop when the app loses focus. Edit: Is the right way to use

LiveData.observeAsState()

? It seems like that works.

StateFlow.collectAsState()

didn't work as well, seems like some weird race condition in my code.

Wouuuahhhh you can’t set

.dp

on a

TextStyle

? Bold of Compose to fight directly the designers of the world 😂

Text(
    text = "Save this dough recipe!",
    style = TextStyle(fontSize = 16.dp) // doesn't compile
)

Is it possible to load an image from file? Like the ImageView.setImageBitmap? without having to use glide or Picasso , if so which will be the preferred type of image png jpeg? Thanks a lot!!

Hello. Does anyone know an analogue of SwipeToRefreshLayout?

Woah this looks cool! https://zeromod.in/posts/jetpack-compose-desktop/

The compose compiler treats compose functions in much similar way the kotlin compiler does to suspend functions. Correct? My curiosity is, why did the Compose Dev team decide to go with annotations (i.e.

@Compose

) instead of making compose a reserved word, similar to suspend functions? Knowing this was much influenced by JB, if the annotations approach seemed more convenient, why didn't they go with it for suspend functions? (i.e

@Suspend

)

Hi, Everyone I just started exploring Compose and coming from SwiftUI this feels at home, I tried looking for documentation on all the available API but could not find it, can someone please guide me to the Compose API docs (If they exist) ?

I am trying to implement refreshing in a composable list. But after refreshing clickable stops working. I think there is some issue with my approach but I am unable to get it. https://github.com/amar1995/ModularNewsApp/blob/main/app/src/main/java/com/amar/modularnewsapp/ui/article/ArticleView.kt#L51

Hello, is there a way to blur a Composable? 😱 If not, how could I achieve that?
