【鸿蒙开发实战教程】在MacOS上如何使用 Flutter 构建鸿蒙APP
有很多小伙伴不知道该从哪里开始学习鸿蒙开发技术？也不知道鸿蒙开发的知识点重点掌握的又有哪些？自学时频繁踩坑，导致浪费大量时间。结果还是一知半解。所以有一份实用的鸿蒙（HarmonyOS NEXT）全栈开发资料用来跟着学习是非常有必要的。
·
前言
根据研究机构Counterpoint Research发布的最新数据，2024年第一季度，鸿蒙OS份额由去年一季度的8%上涨至17%，iOS份额则从20%下降至16%。这意味着，华为鸿蒙OS在中国市场的份额超越苹果iOS，已成中国第二大操作系统。
随着鸿蒙市场份额的不断提升，相应的岗位也会迎来一个爆发式的增长。这对于想要换赛道的程序员来说是一个非常好的消息，话说大家最近有想法转型鸿蒙开发吗？
目前各大厂商纷纷与华为合作构建鸿蒙版移动应用，华为内部也主导适配目前的主流跨平台方案Flutter，并提供反向适配支持，此文将分享如何在Mac上构建鸿蒙App。
一、Harmony Flutter
目前社区最新支持 Flutter 3.7.12 OpenHarmony-SIG/flutter_flutter (gitee.com)
二、Node 环境配置
1、Node 管理工具 nvm
nvm: github.com/nvm-sh/nvm
2、安装 nvm
i): 下载并安装
curl -o- raw.githubusercontent.com/nvm-sh/nvm/… | bash
ii): 添加环境变量到 ~/.zshrc
#nvm
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
3、使用 nvm 管理 node
i): 安装 node nvm install
$ nvm install 16
Now using node v16.9.1 (npm v7.21.1)
ii): 切换 node 版本 nvm use
arduino复制代码$ nvm use 16
Now using node v16.9.1 (npm v7.21.1)
iii): 查看 node 版本 nvm -v
$ node -v
v16.9.1
4、在用户目录 /User/xxx/ 创建 .npmrc 文件，配置如下
registry=https://repo.huaweicloud.com/repository/npm/
@ohos:registry=https://repo.harmonyos.com/npm/
三、Java 环境配置
1、安装和查看本地 java 版本及 jdk 路径
a) 安装Java11 和 Java 17
鸿蒙签名工具基于 Gradle 7.1 编译构建（需要jdk11）
ohsdkmgr 必须jdk17+
brewinstallopenjdk@11brew install openjdk@11brewinstallopenjdk@11 brew install openjdk@17
b) 查看 java 路径 /usr/libexec/java_home -V
$ /usr/libexec/java_home -V
Matching Java Virtual Machines (3):
17.0.9 (x86_64) "Homebrew" - "OpenJDK 17.0.9" /usr/local/Cellar/openjdk@17/17.0.9/libexec/openjdk.jdk/Contents/Home
11.0.21 (x86_64) "Homebrew" - "OpenJDK 11.0.21" /usr/local/Cellar/openjdk@11/11.0.21/libexec/openjdk.jdk/Contents/Home
1.8.391.13 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
/usr/local/Cellar/openjdk@17/17.0.9/libexec/openjdk.jdk/Contents/Home
2、Java版本管理工具
a) 安装 jenv brew install jenv
b) 添加环境变量 ~/.zshrc
export PATH="$HOME/.jenv/bin:$PATH"
eval "$(jenv init -)"
c) 添加 jdk 到 jenv jenv add
jenv add /usr/local/Cellar/openjdk@17/17.0.9/libexec/openjdk.jdk/Contents/Home
d) 查看 jenv 管理的 jdk 版本 jenv versions
$ jenv versions
system
1.8.0.391
11.0
11.0.21
17.0
* 17.0.9 (set by /Users/xxx/.jenv/version)
openjdk64-11.0.21
openjdk64-17.0.9
oracle64-1.8.0.391
e) 切换 jdk 版本 jenv global
$ jenv global 11.0.21
f) 查看当前使用 java 版本 java -version
openjdk version "17.0.9" 2023-10-17
OpenJDK Runtime Environment Homebrew (build 17.0.9+0)
OpenJDK 64-Bit Server VM Homebrew (build 17.0.9+0, mixed mode, sharing)
3、Gradle 配置
i): 下载 gradle7.1: https://gradle.org/releases/
ii): 添加 gradle 环境变量
export PATH=/Users/xxx/ohos/tools/gradle-7.1/bin:$PATH
四、同步引擎代码
1、文件夹目录分布结构如下
2、下载 depot_tools
$ git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
3、设置环境变量：
export PATH=/Users/xxx/ohos/flutter/depot_tools:$PATH
4、创建 engine 目录，创建文件 .gclient并添加以下代码
solutions = [
{
"managed": False,
"name": "src/flutter",
"url": "git@gitee.com:openharmony-sig/flutter_engine.git",
"custom_deps": {},
"deps_file": "DEPS",
"safesync_url": "",
},
]
5、切换到 engine 目录，执行gclient sync执行完成如下
五、Harmony SDK 配置
1、Command Line Tools 配置: HarmonyOS开发者网站
●Command Line Tools for HarmonyOS
●Command Line Tools for OpenHarmony
a): 设置环境变量
#Open Harmony SDK & HDC
export HDC_SERVER_PORT=7035
export OHPM_HOME=/Users/xxx/ohos/tools/oh-command-line-tools/ohpm
export PATH=/Users/xxx/ohos/tools/oh-command-line-tools/sdkmanager/bin:$PATH
export PATH=$PATH:$OHPM_HOME/bin
export OHOS_SDK_HOME=/Users/xxx/ohos/tools/oh-command-line-tools/sdk
export HDC_HOME=/Users/xxx/ohos/tools/oh-command-line-tools/sdk/11/toolchains
#export HDC_HOME=/Users/xxx/ohos/tools/hwsdk/openharmony/9/toolchains
export PATH=$PATH:$HDC_HOME
export PATH=/Users/xxx/ohos/tools/command-line-tools/sdkmanager/bin:$PATH
export HOS_SDK_HOME=/Users/xxx/ohos/tools/hwsdk
b): 执行 ohsdkmgr list, API(10、11) 需去官网自行下载：构建详情 (openharmony.cn)
c): 下载完成后放sdk这个层级下
d): 分别进入
●sdk/11/ets/build-tools/ets-loader
●sdk/11/js/build-tools/ace-loader
e): 执行npm install
f): 将oh command tools 里面的 native 文件夹拷贝至 engine/ndk/mac/4.0 目录下，如下图
g): 编译引擎，切换到 engine 目录下，执行 make 命令（此过程预计1小时左右）
编译出来的产物
●ohos_debug_unopt_arm64
●ohos_release_arm64
2、鸿蒙签名配置
a): 下载鸿蒙签名工具：
git clone https://gitee.com/openharmony/developtools_hapsigner.git
b)：设置环境变量
#Harmony sign tool
export SIGN_TOOL_HOME=/Users/xxx/ohos/tools/developtools_hapsigner/autosign
c): 增加 profile_tmp_template.json 内容如下, 其中 {{ohosId}} 为创建的 Flutter 应用名称
{
"version-name": "2.0.0",
"version-code": 2,
"app-distribution-type": "os_integration",

"issuer": "pki_internal"
}
d): 编辑配置文件
●autosign.config
●createAppCertAndProfile.config
修改值：sign.profile.inFile=profile_tmp.json
e): 切换 Java 版本11 (签名工具基于Gradle 7.1编译构建)
f): 切换至 developtools_hapsigner/hapsigntool **目录，**执行 gradle build 或者 **gradle jar,**确保 hap-sign-tool.jar 生成
