track reads of State

Text()
Button()

and on using the largest font in the device I want to have them both visible, text and button, and if needed to break the content in two lines, is it even possible?
So far, I only managed to have them both visible with ellipse of their textmyanmarking

@Composable

Button(onClick = { onClick() } { ... }

(this is probably a more general kotlin question, but I see both patterns in compose code and it's unclear if one is better / worse than the other)Billy Newman

I am trying something along these lines

in a scrollable column and I realized that by default the column won't scroll to the bottom if it goes off screen. Attached gif of what I mean - the TextField
grows until it reached the height of the Column
, then it goes off-screen - but I can still scroll to it. Can I make the scroll position follow focus? I'd expected that to happen by default, maybe I'm doing something wrong?
val scrollState by remember { mutableStateOf(ScrollState(0)) }
var value by remember { mutableStateOf("") }
Column(
Modifier
.padding(8.dp)
.height(60.dp)
.verticalScroll(scrollState)
) {
BasicTextField(
modifier = Modifier
.fillMaxWidth()
.background(Color.White)
.padding(8.dp),
value = value,
onValueChange = { value = it }
)
}

from Accompanist
composable(...) {...}
is recomposed multiple times due to animation. so every value inside the composable
lambda should be `remember`ed right? for extracting arguments it doesn't really matter because they are static but with remember
we avoid constant extraction of arguments?
what about hiltViewModel
inside composable
lambda?
is it ok to do something like this:
composable(
route = Screen.Checkout.route,
arguments = ...,
enterTransition = { forwardTransitionSharedAxisXIn() },
exitTransition = { backwardsTransitionSharedAxisXOut() },
) { backStackEntry ->
val someArg = remember { backStackEntry.arguments!!.getFloat("arg") }
val viewModel = hiltViewModel<CheckoutViewModel>(backStackEntry)
CheckoutScreen(
...
navigateUp = navController::popBackStack,
)
}

inside an AbstractComposeView
, contained in a ScrollView(in an xml layout)? it seems there is no way around the exception of
Nesting scrollable in the same direction layouts like LazyColumn and Column(Modifier.verticalScroll()) is not allowed.

- seems to have mutability issues and I didn't found any copy/clone method.
• @Composable () -> Unit
- for custom rendering icon is too benevolent for me
• @Composable () -> Painter
- is what I'm ended up. Is it the correct solution?Ashu

01/26/2022, 2:25 PMvar show by rememberSaveable { mutableStateOf(false) }
causes ClassCastException: Boolean can't be cast to String
on configuration change. remember { ... }
works fine, of course.
afaik, rememberSaveable
uses bundle to save values so it should be fine, no?Guilherme Delgado
