🐛 [firebase_analytics] Obfuscation distrubs Google Analytics screenview event

Bug report

Describe the bug I have encountered this issue before on FirebaseCrashlytics, and I have already created discussion on both Stackoverflow & here #8163 (stackoverflow link in discussion) Obfuscated app bundle clearly does not show screen names(classnames).

I can clearly see the wanted results on Firebase DebugView.

However, I cannot see app that created in release mode.

Android (unwanted result)

iOS (wanted result)

Steps to reproduce

Steps to reproduce the behavior:

Create obfuscated app bundle in release mode for android.
Install the app to android device.
Navigate between several screen
Check Google Analytics.

Expected behavior

To be able to see screen/class names clearly.
