Need to update for androidX version

[haikalpe123]

Just a simple request, please update this plugin so it completely compatible with a project that has been migrated to androidX. Thanks!

Seems to work here on androidX

I don't think this project is compatible with AndroidX. This plugin breaks a release build when any other plugin (or the Flutter project) are using AndroidX.
