Answer 1

Найдите cupertino_icons в файле .packages и удалите папку (без lib)

, поэтому, если у вас есть

cupertino_icons:file:///Users/myuser/.pub-cache/hosted/pub.dartlang.org/cupertino_icons-0.1.2/lib/

, удалите

cupertino_icons:file:///Users/myuser/.pub-cache/hosted/pub.dartlang.org/cupertino_icons-0.1.2/

и снова запустите flutter packages get.
