Error during upgrade to 4.0.6

Alarm plugin version
ex: 0.2.9 (please update to the latest version before submitting the issue)
^4.0.6

I've used version 3.1.5 before. But this time I tried to upgrade to version 4.0.6 but I can't [flutter pub get] because of an error like the image above. Can you tell me how?
