I haven't worked with custom views ever, but for my first attempt, my designer gave me this. Is there a way that I can figure out what kind of curve this is, or should I be asking my designer for the path or curve specs or something? It doesn't make sense to me how to draw this curve programatically that'll work on tablets and phones of all sizes.

I'm having a little trouble with Intrinsics. I would like for the Text (yellow) to align with the bottom of only be as tall as the Image as indicated by the red dotted line. Can anyone spot if I am using

IntrinsicSize.Min

Hello everyone, we needed a RevealSwipe for the Card, so we wrote our own one. Maybe the library will help someone. https://github.com/ch4rl3x/RevealSwipe

Hi Devs, anyone idea about how to add splash screen in jetpack compose

What I do is in the mainactivity where screens are dispatched make one of them being the setup screen, and perform all initializations on that screen when they are done I set the current screen to the main one .... But I'm a little bit concerned about startup times of compose app, I'm not sure 100% but I feel they have sensible increased in the last two betas .

I have a LazyColumn that, when the page loads, must be initialised to have a particular item on top, so I do

val listState = rememberLazyListState()

LaunchedEffect(itemIdx) {
  coroutineScope.launch {
    listState.scrollToItem(itemIdx)
  }
}

But this has a rather jarring effect, in that you see the thing scroll to position - what I want is for it just to be there ready when the page opens

Compose Navigation: is there a way to receive a callback each time a composable is popped from the backstack?

Hi All, Any idea what will be a best approach on building a dragabble Layout. For example by default it is just a Row with some initial height with the drag handle on the middle and then we can drag it up and the height increases and shows rest of the content. Just like we have the gesture in BottomSheet.

I have a Unit Test which uses @RunWith(RobolectricTestRunner) and a compose test rule. However, when i start this simple test, i get the following error:

Functions that involve synchronization (Assertions, Actions, Synchronization; e.g. assertIsSelected(), doClick(), runOnIdle()) cannot be run from the main thread. Did you nest such a function inside runOnIdle {}, runOnUiThread {} or setContent {}?

How can i possibly not run my assertions/clicks on the main thread? What did i mess up here?

I am writing a file manager, when I click on the folder, the LazyColumn items data will be reloaded to enter the folder, then how can I remember the list position of the previous page so that I can automatically display it to the correct one when I return next time position, for example, the path

a/b/c

, when go to

c

, I should save the location of

a

and

b

Hey everyone, I'm building a simple 

DatePicker

 and I'm trying to display all the days of the month, e.g. 1..31 I tried using a column of rows for each month, with the months being displayed in a 

Pager

, similar to a regular 

DatePicker

 .. However, the performance of it was pretty terrible. I replaced the rows and columns with a 

LazyVerticalGrid

, the performance improved significantly, although a stutter could still be seen when moving between pages. Is anyone else experiencing similar performance problems? I am testing on a middle-end phone, but the old Android 

DatePicker

 and 

ViewPager

 work fine on it.

what happens to

myNav

object, in case both

model

and

navController

are immutable? will it get instantiated new at each recomposition?

@Composable
fun Navigation(model : MyModel) {
   val appState by model.stateFlow.collectAsState()
   ...
   val navController = rememberNavController()
   val myNav = MyNav(model, navController)
   ...
}
