Hi @cb, Just check with you… I can get your

implementation "dev.chrisbanes.accompanist:accompanist-coil:0.6.0"

from

mavenCentral()

. But I cannot get

0.10.0

from there. Which repo should I get it from? Thanks!

I want to feed search terms into a repository to asynchronous get a list of items, which in turn will be displayed in a LazyColumn. What is the best way to do that with MutableState? Ideally I want to place a debounce in the ViewModel and have that regulate calls to the repository. If I had a LiveData, I would have used a switchMap, for example, observing changes on the search term.

Is there a modifier for maxWidth? Cannot see it. Looking for a wrapContent with percentage max.

fillMaxWidth(X).wrapContentWidth

Hi! Has anyone have this error while trying to run a composable preview in simulated device on Artic fox beta 2?

C:\.....\app\build\intermediates\compile_and_runtime_not_namespaced_r_class_jar\debug\R.jar: The process cannot access the file because it is being used by another process.

Are there docs anywhere about avoiding

onXChanged

as an event name and instead having

onXChange

? I'm reading that back to myself in Florina's voice, but I can't seem to place my finger on where I saw that guidance.

Is it possible to convert the material icons which are of type compose ImageVector to a Drawable. Trying to pass icon as a Drawable to an older library.

is it bad practice to get Activity reference inside Composables like this (LocalContex.current) ?, We need activity Reference in some situations like asking of permissions or currently i am working on BiometricPrompt which requires Activity to open it, so in these cases what would be best approach ?

Is it possible to make Composable tree semitransparent? for example i have red layout and white button inside. I want both to become semitransparent, but i don’t want to see red layout background under button, i want to see this button as semitransparent white (see underlay layout behind it)

I can't find anything in the docs, but when using Crossfade in a column with a composable that add multiple views the views are stacked and not in columns as it is without the Crossfade. Is this a normal behavior?

I noticed that

Typograhpy

class is now not a

data class

(it used to be), but has the same semantics. Why is this so? If I'm making my own

Typography

-like class why shouldn't I use

Something that i dont’t understand with Compose. Why when i toggle theme icons (checkboxes mock) not changes?

isAppDarkTheme()

surely works correct, colors depends on it. I checked with logs what lays in the

res

val and it changes! Why

Icon

can not recomposing? Another strange thing is that there are 4 “checkboxes”, but when i toggled theme i saw sometimes only one, sometimes two log lines (

log

prints from

else

block)

I wrote a tutorial for creating a custom weekly schedule layout like in Google Calendar with Compose. It was my first time working with custom layouts so there might have been even simpler ways to do some things (any feedback would be appreciated), but I was pleasantly surprised by how easy and short (~230 lines) it ended up being! https://danielrampelt.com/blog/jetpack-compose-custom-schedule-layout-part-1/

Hmm, why Icon with painter not changing on recompose? I have mechanics to change dark theme. And line below works: icons changing when app theme change (used for example just random vectors)

Icon(
    imageVector = with(Icons.Default) { if (isAppDarkTheme()) DateRange else KeyboardArrowRight },
    contentDescription = null
)

but if i replace it with resources icon not changing

Icon(
    painter = painterResource(id = if (isAppDarkTheme()) R.drawable.ic_checkbox_on_night else R.drawable.ic_checkbox_on_day),
    contentDescription = null
)

navController.previousBackStackEntry?.savedStateHandle.set()

still a valid way to pass return values from a screen to the previous screen in the backstack using

navigation-compose

? Are there any other preferred ways? (asking coz I didn’t notice it in the navigation compose docs)

julioromano

05/27/2021, 3:45 PM

Other unrelated

navigation-compose

question: Is it possible to scope a

viewModel()

to a nested navigation graph? (So that 2 screens in a nested graph can share state without making that state “global”)

I'm trying to integrate a complex android view (Mapbox) with compose. I can't figure out how to handle updating/getting state that's "owned" by the view. For example, I was planning on the following api

val state = rememberMapboxState(initialPosition, style)
MapboxView(state)

// later
state.animatePosition(newPosition)

The problem is I can't figure out how to have a method on the state trigger an update to the

AndroidView

. I'm considering having the state have a flow of events that the

MapboxView

attaches to in the `AndroidView`'s

update

, but I was wondering if there's a better approach

I could be wrong about this, but I believe in your

MapboxState

the position member would need to be a

MutableState

. Since the entire state is passed into your

MapboxView

(which I'm assuming is your composable wrapper?), when that state is updated (such as by calling

animatePosition

) then your mapbox composable will automatically recompose

Daniel

05/27/2021, 8:53 PM

Thanks. The problem is that model (state tracked in parent, auto-recompose on change) doesn't work with this specific example because this view really wants to keep the state itself for various reasons

I ended up solving it by having the component register the MapboxState with the view so that you can call methods on the state you passed in and have them forwarded to the view
