颤振启动错误：版本解决失败

Question

我已经下载了一个 Flutter 项目并将 lib、assets 和 pubsec.yaml 文件放在一个新项目中。 “flutter packages get”后有超过1k+的错误。这是错误：

Because fluttermultigrocery depends on flutter_localizations any from sdk which depends 
on intl 0.17.0-nullsafety.2, intl 0.17.0-nullsafety.2 is required.

So, because fluttermultigrocery depends on intl ^0.16.1, version solving failed.
pub get failed (1; So, because fluttermultigrocery depends on intl ^0.16.1, version solving failed.)

这是我的 pubsec.yaml 依赖项：

dependencies:
  flutter:
    sdk: flutter
  flutter_localizations:
    sdk: flutter


  cupertino_icons: ^0.1.3
  optimized_cached_image: ^0.1.15

只需删除会产生问题的依赖版本即可 like => firebase_core: (不要指定版本) firebase_messaging：（不指定版本）
