you should use 1.0.0 version of cupertino in your pubspec.yaml.您应该在您的 pubspec.yaml 中使用 1.0.0 版本的 cupertino。 I think there is a problem with new version of cupertino我认为cupertino的新版本有问题
cupertino_icons: ^1.0.0

As of 2021-03-10 or earlier, it is no longer necessary to use cupertino_icons 1.0.0 or switch to the beta update channel ( flutter channel beta ).从 2021-03-10 或更早开始，不再需要使用 cupertino_icons 1.0.0 或切换到 beta 更新频道（ flutter channel beta ）。 Just upgrade ( flutter upgrade ) and re-run flutter pub get .只需升级（ flutter upgrade ）并重新运行flutter pub get 。 For details, see issue 72231 .有关详细信息，请参阅问题 72231 。
