Hi there,

Started seeing following when I run Android build when using the containerSize to get the screen height, can someone help to check..

val container = LocalWindowInfo.current
val screenHeight = with(LocalDensity.current) {
    container.containerSize.height.dp.toPx()
}

error : Unresolved reference: containerSize

Hey @Suresh Maidaragi
I don’t know why IDE suggests containerSize hint in commonMain, but containerSize is not marked as actual value under the hood

actual interface WindowInfo {
    actual val isWindowFocused: Boolean

    actual val keyboardModifiers: PointerKeyboardModifiers
        get() = WindowInfoImpl.GlobalKeyboardModifiers.value
    
    val containerSize: IntSize get() = IntSize.Zero
}

so you can’t use it in commonMain

So you need to define your own expect function like this:

@Composable
expect fun getScreenWidth(): Dp

Android implementation:

@Composable
actual fun getScreenWidth() = LocalConfiguration.current
    .screenWidthDp
    .dp

Others:

@OptIn(ExperimentalComposeUiApi::class)
@Composable
actual fun getScreenWidth() = LocalWindowInfo.current
    .containerSize
    .width
    .dp
