一：适配条件

开源社区在在4月上旬发布了flutter 3.22版本的鸿蒙分支，之前的分支过于老旧，因此可以尝试把自己的项目适配运行

鸿蒙flutter分支地址：

https://gitcode.com/openharmony-sig/flutter_flutter/tree/3.22.0-ohos

已适配三方库地址：

https://gitcode.com/openharmony-sig/flutter_packages#openharmony%E5%B9%B3%E5%8F%B0%E5%B7%B2%E5%85%BC%E5%AE%B9%E5%BA%93

适配过程问题记录

（1）环境配置问题

按照文档配置环境后运行flutter doctor报ohsm sdk找不到，如果按报错去配置环境安装鸿蒙包管理器会很麻烦

直接运行

flutter config --ohos-sdk /Users/vence/Library/OpenHarmony/Sdk（这个地址是自己鸿蒙SDK的安装地址）

如果没有下载sdk在DecEco中自己配置一下

（2）Concurrent modification during iteration: Instance(length:2) of’_GrowableList 报错

此问题查阅资料后为flutter3.22分支上的问题，存在编译问题
解决方案：https://github.com/flutter/flutter/issues/148611

项目全局注释掉MaterialState相关的代码后编译通过。

（3）三方插件寻找替换

已适配三方库地址：

https://gitcode.com/openharmony-sig/flutter_packages#openharmony%E5%B9%B3%E5%8F%B0%E5%B7%B2%E5%85%BC%E5%AE%B9%E5%BA%93

把自己的使用到的三方库查找一遍，如果是纯dart库则不需要替换。涉及到与原生交互的三方库需要替换

以下是自己项目的三方库配置供大家参考
