Hello! I am new to Kotlin and Android and I want to use the

WindowWidthSizeClass

class as used in “Reply” app tutorial (https://github.com/android/compose-samples/blob/00fe2156693d381c44efeb202718f3ecb8[…]bdfc61/Reply/app/src/main/java/com/example/reply/ui/ReplyApp.kt), but it seems that I cannot use the class because it is not included in the Compose library. Does anybody have any idea how to fix this? Thank you for any help!

You need the

androidx.compose.material3:material3-window-size-class

dependency if you want the window size class APIs

Oh right! Thank you!
