Flutter 1.9.1 hotfix 2 proguard issue. Won't compile. #40218
Description
So I was building my app and deploying it to Google Play normally, now after STABLE version 1.9.1+hotfix.2 this is happening and I can't seem to build it....
Using channel dev got the same issue.
Using channel master the problem went away BUT ... it´s master branch and not even dev.
Logs
Note: the configuration keeps the entry point 'io.flutter.plugins.googlemaps.PolylinesController { void addPolyline(java.lang.String,com.google.android.gms.maps.model.PolylineOptions,boolean); }', but not the descriptor class 'com.google.android.gms.maps.model.PolylineOptions'
Note: there were 1 references to unknown classes.
You should check your configuration for typos.

You may need to add missing library jars or update their versions.
If your code works fine without the missing classes, you can suppress
the warnings with '-dontwarn' options.
