Flutter集成image_picker后项目构建失败求助

问题原因 #

你使用的image_picker: 0.8.6是过时版本，与当前Flutter 3.24.0版本不兼容，导致依赖的平台插件（如image_picker_ios）出现类型引用错误。

解决步骤 #

• 修改pubspec.yaml中的image_picker依赖为兼容的新版本，示例：

  image_picker: ^1.1.1
  

• 执行以下命令清理缓存并重新获取依赖：

  flutter clean
  flutter pub get
  

• 重启IDE（如Android Studio），确保缓存完全刷新。
