google_sign_in_dartio dependency

[rlfolden]

I built the example targeting macos and get the following errors:

Because google_sign_in_dartio >=0.0.7 depends on shared_preferences_macos ^0.0.1+10 and google_sign_in_dartio <0.0.7 depends on shared_preferences_macos ^0.0.1+6, every version of google_sign_in_dartio requires shared_preferences_macos ^0.0.1+6. And because shared_preferences >=2.0.0 depends on shared_preferences_macos ^2.0.0, shared_preferences >=2.0.0 is incompatible with google_sign_in_dartio. So, because google_signin depends on both shared_preferences ^2.0.5 and google_sign_in_dartio any, version solving failed. pub finished with exit code 1 Process finished with exit code 1
