开发HarmonyOS Flutter插件的详细指南
# HarmonyOS Flutter 插件开发详细指南
## 0. 环境设置
*前提条件*: 配置 HarmonyOS Flutter 环境
*参考资料*: [HarmonyOS Flutter 环境设置指南](https://juejin.cn/post/7317214081261207603)
*注意*: 下载和编译引擎耗时较长。如需可用的预构建引擎，请联系获取。
------
## 1. 获取原始插件代码
```
git clone <original_plugin_repository>
```
------
## 2. 生成 OHOS 目录
```
# 选项 1: 直接生成（可能失败）
flutter create -t plugin --platforms ohos
# 选项 2: 创建演示项目并复制
flutter create -t plugin --platforms ohos demo
cp -r demo/ohos ./
```
------
## 3. 配置本地依赖
在 `pubspec.yaml` 中添加本地依赖：
```
dependencies:
your_plugin:
path: ../path_to_plugin
```
## 4. 构建插件包
```bash
flutter build hap \
--local-engine-src-path /path/to/ohos_flutter/src \
--local-engine ohos_release_arm64
```
*成功输出*：
```markdown
√ Built build/hap/release/entry-release.hap (XX.XMB)
```
------
## 5. 验证生成的文件
成功构建后：
## 6. 定位插件 HAR 包
插件输出目录：
```markdown
your_plugin/ohos/build/outputs/
└── har
└── your_plugin_ohos.har # 插件包
```
## 7. 将 HAR 添加到演示项目
将 HAR 复制到演示项目：
```bash
cp your_plugin_ohos.har demo_portal/module/ohos/libs/
```
------
## 8. 配置 HAR 依赖
## 9. 初始化插件
## 10. 测试插件功能
## 11. 开发原生实现
按照以下步骤进行原生开发：
1. 分析现有的 iOS/Android 原生逻辑
2. 在 `ohos/src/main/cpp/` 中创建 HarmonyOS 等效实现
3. 实现平台接口: cpp
