Read and documentation and use the correct version of Get.
You're using Get stable version on Beta/Dev/Master branch of Flutter.

sorry, still getting the same error with get: ^2.0.1-dev with flutter Flutter (Channel dev, v1.18.0-8.0.pre, on Mac OS X 10.15.1 19B88, locale en-US)

In fact, the version released yesterday of the Dev branch has problems with two internal packages that used the same variable, and is causing conflict in the lib. I'm going to fix the mistake for myself now.
Thanks for mentioning the version you are using, it was trivial to track down the error.
