当我们使用 VSCode 调试项目时候，出现了下述错误

主要原因是我们在安卓原生项目中配置了 flavorDimensions "buildType"
导致调试时候找不到对应构建的 apk 包，类似这种

productFlavors {
  app_dev {
    dimension "buildType"
  }
  app_test {
    dimension "buildType"
  }
  app_prod {
    dimension "buildType"
  }
....
}

这时候我们需要 在项目 .vscode 打开 launch.json

{
   "name":"app name",
   "request":"launch",
   "type":"dart",
   "args":[
      "--flavor",
      "app_dev'"
   ]
}

配置以后运行即可。
