HarmonyOS 鸿蒙Next中flutter接入适配指导

• 开发限制

  Windows环境下flutter工程和依赖的插件工程需要在同一个磁盘。

• 环境配置 请从OpenHarmony SDK下载配套开发工具
  下列环境变量配置，类Unix系统（Linux、Mac）下可直接参照配置，Windows下环境变量配置请在‘编辑系统环境变量’中设置

  i. 配置OpenHarmony SDK和环境变量

  • API12, deveco-studio-5.0 或 command-line-tools-5.0

  • 下载jdk17并配置环境变量

    # mac环境
    export JAVA_HOME=<JAVA_HOME path>/Contents/Home
    export PATH=$JAVA_HOME/bin:$PATH
    
    # windows环境
    JAVA_HOME = <JAVA_HOME path>
    PATH=%JAVA_HOME%\bin
    

  • 配置环境变量 (SDK, node, ohpm, hvigor)

    # mac环境
    export TOOL_HOME=/Applications/DevEco-Studio.app/Contents # mac环境
    export DEVECO_SDK_HOME=$TOOL_HOME/sdk # command-line-tools/sdk
    export PATH=$TOOL_HOME/tools/ohpm/bin:$PATH # command-line-tools/ohpm/bin
    export PATH=$TOOL_HOME/tools/hvigor/bin:$PATH # command-line-tools/hvigor/bin
    export PATH=$TOOL_HOME/tools/node/bin:$PATH # command-line-tools/tool/node/bin
    
    # windows环境
    TOOL_HOME = D:\devecostudio-windows\DevEco Studio
    DEVECO_SDK_HOME=%TOOL_HOME%\sdk
    PATH=%TOOL_HOME%\tools\ohpm\bin
    PATH=%TOOL_HOME%\tools\hvigor\bin
    PATH=%TOOL_HOME%\tools\node
    

  ii. 通过代码工具下载当前仓库代码git clone https://gitcode.com/openharmony-tpc/flutter_flutter.git，指定dev或master分支，并配置环境

  ```bash
  export PUB_CACHE=D:/PUB
  export PATH=<flutter_flutter path>/bin:$PATH
  export PUB_HOSTED_URL=https://pub.flutter-io.cn
  export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
  ```
  

  iii. 上述所有环境变量的配置（Windows下环境变量配置请在‘编辑系统环境变量’中设置），可参考下面的示例（其中user和具体代码路径请替换成实际路径）：

  ```bash
  #依赖缓存
  export PUB_CACHE=D:/PUB(自定义路径)
  
  # 国内镜像
  export PUB_HOSTED_URL=https://pub.flutter-io.cn
  export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
  
  # 拉取下来的flutter_flutter/bin目录
  export PATH=/home/<user>/ohos/flutter_flutter/bin:$PATH
  
  # HamonyOS SDK
  export TOOL_HOME=/Applications/DevEco-Studio.app/Contents # mac环境
  export DEVECO_SDK_HOME=$TOOL_HOME/sdk # command-line-tools/sdk
  export PATH=$TOOL_HOME/tools/ohpm/bin:$PATH # command-line-tools/ohpm/bin
  export PATH=$TOOL_HOME/tools/hvigor/bin:$PATH # command-line-tools/hvigor/bin
  export PATH=$TOOL_HOME/tools/node/bin:$PATH # command-line-tools/tool/node/bin
  ```
