cupertino_icons: 冲突问题和建议使用equatable

[chanreylee]

这个 cupertino_icons 库版本差得有点多。

Because data_plugin >=0.0.18 depends on cupertino_icons ^0.1.3 and flutter_combat depends on cupertino_icons ^1.0.1, data_plugin >=0.0.18 is forbidden.
So, because flutter_combat depends on data_plugin ^0.0.18, version solving failed.
pub get failed (1; So, because flutter_combat depends on data_plugin ^0.0.18, version solving failed.)
