Need proguard rule when using androidx ViewModel

[edipo2s]

Describe the bug
When using androidx ViewModel, after set minifyEnabled true, my app crashes with message:
No compatible definition found for type 'com.app.b.a.a'. Check your module definition

To Reproduce
Steps to reproduce the behavior:

1. Create a app with androidx ViewModel dependency
2. Declare a viewmodel dependency
3. Request the viewmodel dependency using by viewmodel
4. Set minifyEnable to true
5. Build a release
6. See error

Expected behavior
Find the dependency and don't crash

Koin project used and used version (please complete the following information):
[e.g]: koin-core version 1.0.0-beta3

Additional context
When activating logs, it shows:
declare Factory [class='com.app.b.a.a', binds~(androidx.lifecycle.u)]

Solution
After declare proguard rule:
-keepnames class androidx.lifecycle.ViewModel
logs show:
declare Factory [class='com.app.b.a.a', binds~(androidx.lifecycle.ViewModel)]
and dependency resolution go fine

Thanks, I'll check that!

this is a regression. Koin viewmodel features do not have to break pro guard.
It's fixed in 1.0.0-beta-5, you won't required any proguard rule for Koin.

Seems like the same issue came back in 2.0.0-GA3

Getting a crash when injecting a ViewModel -> can't replicate as it happens only in edge cases, but I do get reports back with that stacktrace from my users.

Caused by org.koin.core.error.NoBeanDefFoundException No definition found for 'c.a.a.a.e.f' has been found. Check your module definitions.

My proguard setup:

-keepnames class androidx.lifecycle.ViewModel
-keepclassmembers class * extends androidx.lifecycle.ViewModel { <init>(...); }
-keepclassmembers class * implements androidx.lifecycle.LifecycleObserver { <init>(...); }
-keepclassmembers class * implements androidx.lifecycle.LifecycleOwner { <init>(...); }
-keepclassmembers class androidx.lifecycle.Lifecycle$State { *; }
-keepclassmembers class androidx.lifecycle.Lifecycle$Event { *; }
-keep class * implements androidx.lifecycle.LifecycleOwner { public <init>(...); }
-keep class * implements androidx.lifecycle.LifecycleObserver { public <init>(...); }

even adding -keep class androidx.lifecycle.** { *; } does not help -> still getting this issue.

Just updated to 2.0.1 with hopes that it will help.
