+5. 获得 har 文件后，按 `flutter.har.BUILD_TYPE.API` 格式重命名文件，如 `flutter.har.debug.11`；替换 `flutter_flutter/packages/flutter_tools/templates/app_shared/ohos.tmpl/har/har_product.tmpl/` 目录下对应文件，重新运行项目工程即可生效。
 
 ps:如果你使用的是DevEco Studio的Beta版本，编译工程时遇到“must have required property 'compatibleSdkVersion', location: build-profile.json5:17:11"错误，请参考《DevEco Studio环境配置指导.docx》中的‘6 创建工程和运行Hello World’【配置插件】章节修改 shell/platform/ohos/flutter_embedding/hvigor/hvigor-config.json5文件。
