????????公司app是用純flutter開(kāi)發(fā)的，目前支持android和iOS，后續(xù)估計(jì)也會(huì)支持鴻蒙harmonyos。目前谷歌flutter并沒(méi)有支持咱們國(guó)產(chǎn)手機(jī)操作系統(tǒng)鴻蒙harmonyos，于是乎國(guó)內(nèi)有個(gè)叫OpenHarmony-SIG的組織，去做了鴻蒙harmonyos適配flutter開(kāi)發(fā)的工作。本文就是基于OpenHarmony-SIG/flutter_flutter去搭建純flutter開(kāi)發(fā)環(huán)境。

1. 鴻蒙開(kāi)發(fā)環(huán)境搭建，鴻蒙開(kāi)發(fā)套件官方下載地址如下：https://developer.huawei.com/consumer/cn/download/
2. 下載鴻蒙版flutter

   git clone -b dev https://gitee.com/openharmony-sig/flutter_flutter.git

3. 下載FlutterEngine構(gòu)建產(chǎn)物（非必選項(xiàng)），網(wǎng)盤下載地址Flutter Engine構(gòu)建產(chǎn)物，FlutterEngine構(gòu)建產(chǎn)物方便用來(lái)在android studio來(lái)運(yùn)行、調(diào)試、打包等鴻蒙harmonyos項(xiàng)目flutter側(cè)代碼，當(dāng)然你也可以通過(guò)DevEco-Studio來(lái)運(yùn)行、調(diào)試、打包等鴻蒙代碼。構(gòu)建命令如下，執(zhí)行改命令之前需要簽名。

   flutter build hap --local-engine=/Users/administrator/Documents/src/out/ohos_debug_unopt_arm64

4. 安裝jdk，版本需為jdk 17，下載地址為Java Downloads | Oracle 中國(guó)
5. 環(huán)境變量配置，注意：拉取下來(lái)的flutter_flutter/bin目錄必須為第二步鴻蒙版flutter下載下來(lái)的bin目錄。

   export PUB_HOSTED_URL=https://pub.flutter-io.cn
   export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn# 拉取下來(lái)的flutter_flutter/bin目錄
   export PATH=/Users/administrator/Documents/flutter_flutter/bin:$PATH# jdk-17.jdk jdk-11.0.17.jdk zulu-8.jdk
   JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-17.jdk/Contents/Home
   PATH=$JAVA_HOME/bin:$PATH:.
   export JAVA_HOME
   export PATH# HamonyOS SDK
   export TOOL_HOME=/Applications/DevEco-Studio.app/Contents # mac環(huán)境
   export DEVECO_SDK_HOME=$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

6. 檢查環(huán)境，運(yùn)行flutter doctor -v檢查環(huán)境變量配置是否正確，Futter與OpenHarmony應(yīng)都為ok
7. 創(chuàng)建Flutter工程

   # 創(chuàng)建工程 方式一 該方式只創(chuàng)建了ohos平臺(tái)
   flutter create --platforms ohos <projectName> # 創(chuàng)建工程 方式二 該方式創(chuàng)建了android,ios,ohos三個(gè)平臺(tái)
   flutter create  <projectName> # 進(jìn)入工程根目錄編譯hap包
   flutter build hap --debug

8. 鴻蒙真機(jī)運(yùn)行Flutter項(xiàng)目

    flutter run --debug -d <deviceId>flutter build hap --debughdc -t <deviceId> install <hap file path>

9. 當(dāng)然我們也可以通過(guò)DevEco-Studio模擬器來(lái)運(yùn)行flutter項(xiàng)目
