解决步骤

清理缓存与构建产物
执行命令清理项目本地缓存：
```
flutter clean
```
清理Flutter全局依赖缓存：
```
flutter pub cache clean
```
重建项目依赖与配置
重新拉取项目依赖：
```
flutter pub get
```
重新生成Windows平台构建配置：
```
flutter create --platforms windows .
```
尝试重新运行项目：
```
flutter run -d windows
```
修复Flutter SDK完整性
强制重新更新Flutter SDK，修复可能的文件损坏：
```
flutter upgrade --force
```
若仍无效，手动删除SDK目录下的packages/flutter/lib/src/painting/image_provider.dart文件，再执行flutter upgrade让SDK自动恢复该文件。
检查Visual Studio环境
确认Visual Studio 2022已安装「Desktop development with C++」工作负载，包含MSVC工具链、Windows SDK等必要组件；也可直接打开项目的windows/Runner.sln文件，在VS中尝试构建，查看更详细的错误提示。
