If firebase crashlytics can de-obfuscate the code by itself, do we really need to add the following lines to achive de-obfuscation?
-keepattributes SourceFile,LineNumberTable # Keep file names and line numbers.
-keep public class * extends java.lang.Exception # Optional: Keep custom exceptions.simply adding minifyEnabled:true is enough? or this will leads to partial de-obfuscation?
