ProGuard rules for BottomBar
ProGuard obfuscates method names and may shrink methods, which are not called. ProGuard also optimizes the bytecode, removes unused code instructions, and obfuscates the remaining classes, fields, and methods with short names. To fix errors and force ProGuard to keep certain code, set up a ProGuard configuration in proguard-rules.pro file.
