I added the androidx-material3-window-size-class-android implementation in my build.gradle.kts (app) file, and got a "- Problem: In version catalog libs, alias 'androidx-material3-window-size-class-android' is not a valid alias." which prevented rebuilding gradle.
After removing that implementation from build.gradle.kts I still keep getting the same error, even after invalidating Caches and downloading everything again. Should I just create a new project and copy the code from the broken one?
In existing projects downloaded from GitHub for codelabs (eg:Reply) the implementation ("androidx.compose.material3:material3-window-size-class") works just fine, but if I create a new project and add it to the build it just goes balooney
implementation(libs.androidx.material3.windowsizeclass)
[libraries]
androidx-material3-windowsizeclass = { module = "androidx.compose.material3:material3-window-size-class", version.ref = "material3WindowSizeClass" }
[versions]
material3WindowSizeClass = "1.2.1"
That solved the problem for me. I hope it's helpful.
