Hi @stx, this should be fixed in the release 0.6.0 of https://pub.dev/packages/package_info_plus, as we have renamed the Method Channel and should avoid collisions with the original package_info.

[miquelbeltran]

Actually I am wrong, with the changes in 0.6.0 may not be enough and we need to rename the objc classes.

[miquelbeltran]

With the changes in 0.6.2 now it should be OK, I renamed the ObjC files on iOS so there's no collision with the package_info plugin, and tested it importing both packages on a project.
