Does this happen if you temporarily remove/disable the pull-refresh part?

We're facing the same issue with TopAppBar
and TopAppBarDefaults.pinnedScrollBehavior
. When scrolling quickly on a lazy layout, the app bar container color does not respond.
Repo:
Video:
val scrollBehavior = TopAppBarDefaults.pinnedScrollBehavior()
Scaffold(
modifier = Modifier
.fillMaxSize()
.nestedScroll(scrollBehavior.nestedScrollConnection),
topBar = {
TopAppBar(
title = {
Text(
modifier = Modifier.fillMaxWidth(),
text = "Hello!",
textAlign = TextAlign.Center,
)
},
scrollBehavior = scrollBehavior,
)
},
) { innerPadding ->
LazyColumn(
modifier = Modifier.padding(innerPadding),
contentPadding = PaddingValues(16.dp),
verticalArrangement = Arrangement.spacedBy(8.dp),
) {
items(100) {
Text(
text = "Item $it",
modifier = Modifier
.fillMaxWidth()
.background(MaterialTheme.colorScheme.surfaceContainerHigh)
.padding(24.dp),
)
}
}
}

I am facing the same bug and i think the root case for it is that the PinnedScrollBehavior
doesn't override the onPostFling
in its NestedScrollConnection
implementation.
I made a crude simple custom version and added
override suspend fun onPostFling(consumed: Velocity, available: Velocity): Velocity {
if (available.y > Velocity.Zero.y)
state.contentOffset = 0f
return super.onPostFling(consumed, available)
}
and then it works fine for me!

Fix the app-bars behaviors to detect end of scroll
Apply a fix to all the behaviors to detect the end of scroll in the post
fling function. This will better ensure an app-bar color change when the
content is scrolled all the way.
