I have a bunch of Recycler views in my app that gets data from the firestore database. Everything went fine in my debug app but when I added minifyEnabled true In my proguard everything worked fine but the activity hosts recycler fails with the below logcat error. I'm totally unaware of how to add the proguard rules for the model classes
I just made my stacktrace and this is the error

May be you have problem because of proguard, to be sure just try by disabling minify in your release build type
buildTypes {
release {
minifyEnabled false
------
}
}
