Flutter项目依赖报错：cupertino_icons版本冲突无法解决

问题重现 #

Resolving dependencies...
Because mi_card depends on cupertino_icons ^0.1.6 which doesn't match any versions, version solving failed.

You can try the following suggestion to make the pubspec resolve:

• Try upgrading your constraint on cupertino_icons: flutter pub add cupertino_icons:^1.0.6
  Process finished with exit code 1

已将cupertino_icons从^1.0.4升级至^1.0.6，执行pub get和pub upgrade后仍报错。

解决方案 #

• 仔细检查pubspec.yaml文件，确认cupertino_icons的版本配置确实是cupertino_icons: ^1.0.6，注意冒号后要有空格，版本号的符号和数字无拼写错误。
• 清理项目缓存与锁定文件：
  1. 执行命令：flutter clean
  2. 删除项目根目录下的.dart_tool文件夹和pubspec.lock文件
• 重新获取依赖：执行flutter pub get（优先用flutter pub命令而非单独pub，避免环境变量导致的命令上下文问题）
• 检查Flutter版本兼容性：
  1. 执行flutter --version查看当前Flutter版本
  2. 如果是较旧版本，执行flutter upgrade升级Flutter到稳定版，再重新执行flutter pub get
• 强制更新指定依赖：执行flutter pub upgrade --major-versions cupertino_icons
