我目前正尝试在Flutter应用程序中实现本地化，但每当我尝试为flutter_localization添加依赖项时，我都会收到以下错误消息：
由于计时器依赖于SDK中不存在的flutter_localization（无法在Flutter SDK中找到包flutter_localization），版本求解失败。
我还在Android Studio中正确地添加了flutter和dart SDK的路径。
下面是我的pubspec.yaml文件：

publish_to: 'none' # Remove this line if you wish to publish to pub.dev

version: 1.0.0+1

environment:
  sdk: '>=2.18.2 <3.0.0'

dependencies:
  flutter:
    sdk: flutter
  intl: ^0.17.0-nullsafety.2
  cupertino_icons: ^1.0.2
  sqflite: any
  shared_preferences: ^2.0.15
  path_provider: any
  flutter_localization:
    sdk: flutter
  flutter_cupertino_localizations: ^1.0.1

dev_dependencies:
  flutter_test:
    sdk: flutter

  flutter_lints: ^2.0.0

flutter:

  uses-material-design: true

没有flutter_localization，我无法访问GlobalMaterialLocalizations，显然，这是最简单的解决方案。我已经尝试了许多解决方案，如检查版本兼容性和更新所有依赖项。你们能帮我吗？
提前致谢！
升级SDK、升级依赖项、重新安装flutter和Dart等
