I also encountered this problem, which is caused by the low version of cordova-android. If you are in ionic cordova platform add android, have noticed that cordova-plugin-file is required for cordova-android version greater than or equal to 6.3.0.

So just run the command:

ionic cordova platform remove android
ionic cordova platform add [email protected]

This will be packaged successfully after running the ionic build.
