I've seen people treat modals (with the legacy view system) as either state or an event. With compose, I'm more inclined to consider the fact that a modal is showing as part of my state for the screen. In my case I'd have an AAC ViewModel with something like

errorModalShowing: Boolean

Not sure if I'm missing some kind of best practice here, but let's take a quick poll! Do you treat modals as: 1️⃣ State 2️⃣ Event

Will the new Material You be used in future Compose?

Hi, is there any good implementation for Navigation in Compose? Btw I have checked docs Actually our team is starting new project but after checking docs i have realised that we have to keep

navController

in main or root Composable and then we either have to pass this to other Composable or we have to get callback in root for navigation(please correct me if i’m wrong here) , so we are not sure how much scalable it is for bigger apps with many screens ? so that’s why i want to check if there is any good implementation of navigation component in compose ?

Hot to inject class to my viewModel in @Composable? I use Koin and I tried to follow documentation but it doesn't work Module:

val welcomeModule = module {
   single<MyService> { MyServiceImpl() }
}

ViewModel:

class MyViewModel(private val myService: MyService) : ViewModel() {
...
}

@Composable function:

@Composable
fun Screen(){
   val myViewModel: MyViewModel= viewModel()
}

I tried:

and put it to viewModel() but it doesn't work

Hi, I have an animation but I don't understand why the boxes are not spaced evenly in it. Please see gif and code in thread. Any ideas?

Is there a way to the decide opening direction of Side Drawer in a Scaffold?

Hi @Doris Liu, Is there a way to seek a Color Animation based on percentage? I essentially need to animate between Colors, ex.

Color.Red -> Color.Yellow -> Color.Green

. I wanted to be able to get the color given a certain percentage. I tried

updateTransition(...)

but it seems that it only applies to a targeted state but not the in-betweens. Any advice? Thanks in advance.

Is there any way to skip code by checking if I'm currently in the preview? I have code that uses

EmojiCompat.get()

and that breaks the preview because EmojiCompat wasnt initialized because as we're inside the preview the application wasn't created. (sth like

View.isInEditMode

but statically available?)

Does anyone know if there are plans to make

SubComposeLayout

and

Intrinsics

work together? For example something like the following:

Row(modifier = Modifier.fillMaxWidth.height(IntrinsicSize.Min)) {
    BoxWithConstraints(...) {
        ...
    }
}

this currently crashes with an IllegalStateException with a message of

Intrinsic measurements are not currently supported by SubcomposeLayout

Any way to “fix” this?

Not directly compose related, but since we've been all using Arctic Fox for some time now. Have people noticed that they have deployed their app in studio, it builds, then installs, but the old build launches again? I've noticed this a handful of times, and a restart of Studio seems to resolve it... but I just hit it again and it killed like an hour of my time. I don't know how to repro, but curious if it's compose related or if someone has a bug tracker issue handy.

@Preview

annotation not working in library module. Is this intentional? I am getting this issue:

The following classes could not be instantiated:
- androidx.compose.ui.tooling.preview.ComposeViewAdapter

Is it a good idea to create this type of UI in Constrainlayout or a custom Layout, and will there be any performance benefit if I pick the latter?

Hey! Any of you used

ThreeTenABP

library to manage dates in Android? As soon as a Date is used in the composables, the Preview fires an error because the timezone data is not registered. Is there anyway to initialize this kind of libraries in Preview mode?

Solved: had to update both android studio and gradle (🤦‍♂️). I'm having troubles upgrading compose to `beta07`:

java.lang.IllegalStateException: function = <anonymous>, count = 4, index = 4

.

beta06

was working fine. I also upgraded navigation to

2.4.0-alpha01

, but didn't help. Full error in thread.

Hi guys, could you please have a look at this? I asked here yesterday but unfortunately I have not managed to make any progress since : https://stackoverflow.com/q/67661974/5513788

I’d create that in a dagger module and inject it into my fragment/activity. With compose, you’re not dealing with individual fragments, so you can’t just scope the view models to the fragment’s ViewModelStore. Does compose provide it’s own ViewModelStore attached to the current composable?

@henrikhorbovyi Looking at the code, i’d say no. FAB is implemented as a surface with a box. And there’s no conditional anywhere that would lead me to believe you can specifically disable it.

But it does seem like a big miss on their part. But, like i said, the beauty of compose is that you can see the source code and actually understand most of it (try that with the FAB class in material design library).

or is this not supported yet?

I have seen some standard composables such as

Row

or

Column

are defined as

inline

. What is the purpose? and does it ever make sense for custom composables to be defined as inline?

i've created helper function related to spacer and invoking them like this :-

SpaceHeight(16.dp)

,

SpacerWidth(16.dp)

@Composable
fun SpacerHeight(size: Dp) {
    Spacer(modifier = Modifier.height(size))
}

@Composable
fun SpacerWidth(size: Dp) {
    Spacer(modifier = Modifier.width(size))
}
