How to fix "dalvik.system.BaseDexClassLoader.findClass" exception in Flutter?

#flutter

Were you excited to release this app just to notice that the app was crashing when trying to load it in production? You are not alone.

In my case, I examined the crash details in the Play Store console. I saw in the stack trace that it was caused by:

Caused by java.lang.ClassNotFoundException:
  at dalvik.system.BaseDexClassLoader.findClass (BaseDexClassLoader.java:218)

Make sure that the package value in /app/src/main/AndroidManifest.xml is the same as android\app\src\main\kotlin\com\example\kombucha_app\MainActivity.kt.

In my case, it wasn't. Once they were the same and I published a new release of the app, it worked.
