解决步骤

清理构建缓存
执行Flutter清理命令移除旧构建产物：
```
flutter clean
```
也可以手动删除项目根目录的build文件夹，以及Android模块下的.gradle文件夹。
更新依赖包
检查pubspec.yaml中path_provider的版本，替换为最新稳定版后执行：
```
flutter pub get
```
同步Gradle兼容配置
打开Android模块的build.gradle文件，确保AGP（版本7.3.0）与Gradle版本匹配（对应Gradle版本需在7.4-7.6区间）。修改后触发Gradle同步，重新下载依赖。
临时禁用D8增量编译
在项目根目录的gradle.properties中添加以下配置：
```
android.enableD8=false
```
之后重新构建项目。
重新构建项目
完成上述操作后执行：
```
flutter run --debug
```
