ProGuard Errors in Non-Android Platforms and Dialog Crashes on iOS

[Lyxot]

I've encountered serious problems with the release build on non-Android platforms, specifically:

• ProGuard produces multiple warningswhen building for non-Android platforms
• The app crashes when attempting to open dialogs on iOS

proguard error logs:

Warning: com.michaelflisar.composedialogs.core.style.BottomSheetStyle$Show$5: can't find referenced method 'androidx.compose.foundation.layout.WindowInsets getNavigationBars(androidx.compose.foundation.layout.WindowInsets$Companion)' in program class androidx.compose.foundation.layout.WindowInsets_notMobileKt

Warning: com.michaelflisar.composedialogs.core.style.BottomSheetStyle$Show$5$2$2: can't find referenced method 'androidx.compose.foundation.layout.WindowInsets getNavigationBars(androidx.compose.foundation.layout.WindowInsets$Companion)' in program class androidx.compose.foundation.layout.WindowInsets_notMobileKt

I've attempted to add ProGuard rules to ignore these warnings:

-dontwarn androidx.compose.foundation.layout.WindowInsets$Companion
-dontwarn com.michaelflisar.composedialogs.core.style.DialogStyleKt
-dontwarn com.michaelflisar.composedialogs.core.style.BottomSheetStyle$Show$5
-dontwarn com.michaelflisar.composedialogs.core.style.BottomSheetStyle$Show$5$2$2

However, while this suppresses the warnings, it doesn't solve the underlying issue causing iOS crashes.

I will upload full logs if you need

It appears the ComposeDialogs library may be using Android-specific Compose APIs that don't exist or work properly on Non-Android Platforms, causing both ProGuard issues during build and runtime crashes.

Sorry for the late reply. If compose does provide a modifier inside its common module it should be save to use it everywhere - can you try if the newest version (compose version is not at 1.8.2) has this problem as well?

This is an iOS issue because it does not happen on windows, android, web... I can't test iOS my own currently...
