cleanUp method
If the prepared package contains anything that has to be cleaned up
(like created temp directories) then cleanUp
takes care of that
Implementation
Future cleanUp(PreparedPackageRef preparedPackageRef) {
stdout.writeln('Cleaning up');
if (preparedPackageRef.tempDirectory != null) {
return Directory(preparedPackageRef.tempDirectory!)
.delete(recursive: true);
}
return Future.value();
}
