This also brings back dialog content size animations issues :( But on all devices this time.
See attached video
Repro:
Dialog(
onDismissRequest = {
if (dialogState.canDismiss.value) {
dialogNavigator.hide()
}
},
properties = properties,
content = {
Surface(
modifier = modifier
.safeContentPadding()
.fillMaxWidth(0.8f)
.animateContentSize(),
shape = shape,
color = backgroundColor,
contentColor = contentColor,
) {
.....A composable that change it's size
}
},
)

Can you give a fuller example for the animateContentSize()
problem?

It does that for all the cases where the content change.
properties = DialogProperties(usePlatformDefaultWidth = false)
var show by remember { mutableStateOf(false) }
LaunchedEffect(Unit) {
delay(1000)
show = true
}
Column {
Text("X")
if (show) {
Text"Y)
}
}
Edit: This was a well known long time issue when not using usePlatformDefaultWidth = false
so we were forced to workaround with that.
Now even with it it trigger that. (Depending on the phone, it's either super slow, or laggy and jumping).

I am seeing a problem with decorFitsSystemWindows = false
where it continues to invalidate the layout even after the animation completes. I don't think that's the problem you're worried about, though.
If I understand correctly, the problem you're seeing is something about it being laggy? And it didn't happen in the previous version, right?
That problem is likely due to the Window resizing on every frame, which is more expensive than the window content resizing on every frame. In a previous iteration, the window size was full screen and the content resized itself. You can resolve this yourself by doing this:
Surface(
modifier = Modifier.safeContentPadding()
.fillMaxSize()
.wrapContentHeight()
.fillMaxWidth(0.8f)
.animateContentSize(),
...
I'll see if I can fix the problem with decorFitsSystemWindows = false
invalidating layout continuously.

Description:
Having this structure:
nav_graph.xml
<navigation
android:id="@+id/nav_graph"
app:startDestination="@id/startFragment">
<fragment
android:id="@+id/startFragment"
android:name="com.example.navbug.StartFragment"
android:label="StartFragment"
tools:layout="@layout/fragment_start">
<action
android:id="@+id/action_startFragment_to_nested_nav_graph"
app:destination="@id/nested_nav_graph" />
</fragment>
<include app:graph="@navigation/nested_nav_graph" />
</navigation>
nested_nav_graph.xml
<navigation
android:id="@+id/nested_nav_graph"
app:startDestination="@id/nestedStartFragment">
<fragment
android:id="@+id/nestedStartFragment"
android:name="com.example.navbug.NestedStartFragment"
android:label="NestedStartFragment">
<action
android:id="@+id/action_nestedStartFragment_to_nestedSecondFragment"
app:destination="@id/nestedSecondFragment"
app:popUpTo="@+id/nestedStartFragment"
app:popUpToInclusive="true" />
</fragment>
<fragment
android:id="@+id/nestedSecondFragment"
android:name="com.example.navbug.NestedSecondFragment"
android:label="NestedSecondFragment" />
</navigation>
I want to achieve this navigation pattern:
StartFragment => NestedStartFragment => NestedSecondFragment =(back)=> StartFragment
I'm trying to implement this by setting the action NestedStartFragment=>NestedSecondFragment with the options [popUpTo=NestedStartFragment, popUpToInclusive=true], so that the resulting stack would be:
0. NestedSecondFragment
1. NestedNavGraph
2. StartFragment
3. NavGraph
When navigating from NestedStartFragment to NestedSecondFragment, the following execption occurs:
java.lang.IllegalArgumentException: Navigator androidx.navigation.fragment.FragmentNavigator@ccc9092 reported navigation to unknown destination id com.example.navbug:id/nestedSecondFragment

at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858)
Right before the navigation, the stack is:
0. NestedStartFragment
1. NestedNavGraph
2. StartFragment
3. NavGraph
When NestedStartFragment is popped on my request, NestedNavGraph is also popped because
"// We never want to leave NavGraphs on the top of the stack" (from NavController.onNavigatorNavigated)
with the effect that eventually the requested destination NestedSecondFragment is pruned from the graph and cannot be reached anymore.
Unless I'm doing something wrong, it seems that NavGraph automatic popping should be avoided if the final destination actually belongs to it.
