Thanks for reporting this. We recently changed the implementation. For FABs, we recommend passing null instead. Moving forward, we are going to provide a nicer UX letting you pass in empty composables. #1 and #2, could you share your use cases for passing empty composables?

I am encountering very similar issue as comment #4. BottomSheetScaffold content is determined by a state. There is a case where content will be only AlertDialog which crashes the app. Setting AlertDialog component inside Box component will fix the crash. I am not sure whether this is expected behaviour or not.

This code will crash the app:

BottomSheetScaffold(
        sheetContent = { Text(text = "Some sheet content") }
    ) {
        AlertDialog(
            onDismissRequest = {
                // NO-OP
            },
            buttons = {
                Text(text = "here goes a button")
            }
        )
    }

I am experiencing the same problem, the last compose version that I used that hasn't this problem is the 1.2.0-beta02

Versions used:

Jetpack Compose version: 1.2.0-rc03

Jetpack Compose Compiler version: 1.2.0

Jetpack Compose component used: BottomSheetScaffold, NavHost

Kotlin version: 1.7.0

When the app starts, and opens the bottom sheet it crashes.

Thanks, we're investigating this. (Fwiw, as a best practice you should do this anyway for the FAB)

We will comment on this issue when the fix has been released.

The following release(s) address this bug.It is possible this bug has only been partially addressed:

• androidx.compose.material:material:1.5.0-alpha02

My team was experiencing this as well. We just upgraded to Compose BoM 2023.03.00 and Kotlin 1.8.10.

For anyone using the Compose BoM for dependencies, you can supply the above alpha version to the dependency and it should override the supplied version in the BoM:

implementation platform("androidx.compose:compose-bom:2023.03.00")

implementation "androidx.compose.ui:ui"
implementation "androidx.compose.foundation:foundation"
// ...
// more deps
// ...
implementation "androidx.compose.material:material:1.5.0-alpha02"

This fixed the problem for us.

Crashes in Compose BOM 2023.05.00, Kotlin 1.8.10 and the Compose compiler 1.4.6.

Using implementation "androidx.compose.material:material:1.5.0-alpha03" resolved the issue.
