Can't we put all these in example-app proguard-rules?

Yes, it is added into example app proguard rules.

Once added into example proguard, we can remove these from here to simplify?

We added 'proguard-rules.txt' here to apply in the release build.

Then we can drop "proguard-rules.pro" here?

Do we need these - not used in our flutter sdk?

Obfuscation can cause app crash in runtime, even if building is fine. We may need to run tests after buidling.
No need to include in this fix, but we can consider it later.
- Remove additional safety rules for Optimizely - Update APK artifacts upload path for minification test - Remove unnecessary Guava classes and warnings - Adjust SLF4J and Logback rules for ProGuard - Remove warnings for missing dependencies in ProGuard configuration
