Is there in Compose Multiplatform common code to detect if the keyboard is open or not?

This is my current approach:

// common
@Composable
expect fun isKeyboardVisible(): Boolean

// android
@Composable
actual fun isKeyboardVisible(): Boolean {
    var isKeyboardOpen by remember { mutableStateOf(false) }
    val view = LocalView.current

    val viewTreeObserver = view.viewTreeObserver

    DisposableEffect(viewTreeObserver) {
        val onGlobalListener = ViewTreeObserver.OnGlobalLayoutListener {
            val rect = android.graphics.Rect()
            view.getWindowVisibleDisplayFrame(rect)
            val screenHeight = view.rootView.height
            val keypadHeight = screenHeight - rect.bottom
            isKeyboardOpen = keypadHeight > screenHeight * 0.15
        }
        viewTreeObserver.addOnGlobalLayoutListener(onGlobalListener)

        onDispose {
            viewTreeObserver.removeOnGlobalLayoutListener(onGlobalListener)
        }
    }

    return isKeyboardOpen
}

// ios
@Composable
actual fun isKeyboardVisible(): Boolean = WindowInsets.Companion.ime.getBottom(LocalDensity.current) > 0

Currently what I'm doing is checking the imePadding's values 🙈

That's the only reliable way that I found at least

[Erik Ziegler]

Can you do this from common?

[Hristijan]

Yes I'm talking about common

[Erik Ziegler]

Can you share your code? 🙂

[Hristijan]

I'm not in front of a computer now but essentially

val bottomImePadding = WindowInsets.ime.asPaddingValues().calculateBottomPadding()

[Erik Ziegler]

I'll give it a try thank you!

Would be awesome to have this build in in compose, but its not even in compose android

[Hristijan]

yeah, i know, i always check if the dp’s value is bigger than 0 and it works, just keep in mind that in between there are values as the keyboard is being animated

Why would compose android include apis for dealing with the IME? The IME is a system thing, there’s nothing Compose-specific about it.

Not compose per se, but it seems to create some frustration (e.g. see comments here https://stackoverflow.com/a/7530328) in the Android community that there is no "simple" solution to detect if the keyboard is open. Regardless this could also be a cool Compose Multiplatform Community Library.
