getAllValueDetailsAsync() returns 0 flags in R8 full mode

[alenjularic]

Describe the bug

Calling methods getAllValueDetailsAsync() or getAllValueDetails() in release builds results in the following error: An error occurred while getting the detailed values. Returning an empty map. Debug builds work normally.

The issue is likely related to R8 full mode, which is on by default in Android Studio Flamingo 2022.2.1.

Adding the following line to ProGuard rules fixes the issue for me, but it isn't optimal: -keep class com.configcat.** { *; }

Or disabling the R8 full mode in gradle.properties also fixes the problem: android.enableR8.fullMode=false

To reproduce

Build a release app and call getAllValueDetailsAsync() or getAllValueDetails(), number of flags returned should be 0.

Expected behavior

Should return the actual number of flags available in ConfigCat dashboard.
