, the memory profiler, after setting focus on/selecting the text field without typing anything, shows that Java allocations are happening non-stop, it keeps goin up until it gets GCed, then start going up again over n over, am I missing something?
MyApplicationTheme {
// A surface container using the 'background' color from the theme
Surface(color = MaterialTheme.colors.background) {
OutlinedTextField(value = "Ok", onValueChange = {})
}
}

for measurement of the child and then another Layout
that will place X amount of those children based on screen height. The problem I ran into was each child I'm placing needs to be unique/not being currently laid out for the system to not give me "Place was called on a node which was placed already"

that comes from view model? I have a Flow
that produces values for LazyColumn
. Do I have to put the values into a SnapshotStateList
or can I feed the LazyColumn
on the fly with the values? How would I do this?Sanendak

When we refresh, we want to update the relative time text but it doesn’t
a recomposition when the time value doesn’t change.
Any idea how to handle this kind of scenario?smit01

and requestPermissionLauncher.launch(permission)
. I have discovered that requestPermissionLauncher.launch(permission)
is responsible for opening the "android permission prompt" false
without waiting for a user action. When I click "Allow" btn the callback is triggered with true
. Is the first run with false inteded? Do we have to suspend here and wait for a user action somehow? I would expect that the callback is only triggered when a button of the prompt is clciked.ursus

I want to dynamically change the inner column width to be the same as the ancestor box (it should be width of device), or some percentage (half or quarter). How can I reference the Box width in order to size the Column(s) properly? Thank you!Carl Benson

inside a Column
with a scroll state, so I now know that I can't nest composables scrolling in the same direction. However, I'm only using LazyVerticalGrid
since the cells can be adaptive, and I don't need its scroll functionality. Is there a way to create a composable that can replicate `LazyVerticalGrid`'s adaptive functionality and removing the scrolling?rajesh

but as soon as you try to do the same thing with a ModalBottomSheetLayout
it throws java.lang.IllegalArgumentException: The initial value must have an associated anchor.
because you are initializing it with a null value. If you just swap the two or more contents instead of setting a null value when you close the ModalBottomSheet
it will work but it won't animate correctly.Se7eN

var position: Offset by mutableStateOf(...)
var rotation: Float by mutableStateOf(...)
...
}
// Then I can do this:
val element = Element(...)
element.position = newPosition
I want to pass this element
object to a composable but don't want it to be mutable. I can create a similar class for an immutable element but then I'd have to update the immutable class whenever I change the Element
class. Is there something else I can do?Fudge

then bugs may appear; since Compose can call the composables at any moment. In this scenario, or in any scenario, when is it likely to happen? I understand the concept but I can't think of any examples when this may actually happen.
