ohos 开发 flutter_module

1.DevEco-Studio 搭建原生工程
使用 flutter_flutter，配置相关的环境变量

使用 flutter_engine 生成的engine产物

2.搭建 flutter_module 工程

1. 创建 flutter子模块工程

flutter create -t module my_flutter_module

2. 编译生成 flutter_module.har

cd my_flutter_module
flutter build har --debug
cd -

3. 复制 EntryAbility.ets 和 Index.ets 到 MyApplication 中

cp my_flutter_module/.ohos/entry/src/main/ets/entryability/EntryAbility.ets MyApplication/entry/src/main/ets/entryability/EntryAbility.ets
cp my_flutter_module/.ohos/entry/src/main/ets/pages/Index.ets MyApplication/entry/src/main/ets/pages/Index.ets

ohos 工程引用 flutter
ohos 工程引用 flutter 工程有两种使用方式

方式一：ohos 工程 引用 har 文件

1. 复制 har 文件
   cp -r my_flutter_module/.ohos/har/* MyApplication/har/

2. 修改 MyApplication/oh-package.json5
   {
   // ...
   "dependencies": {
   "flutter_module": "har/flutter_module.har"
   },
   "overrides": {
   // 有冲突的依赖需要放到这里消除冲突
   "@ohos/flutter_ohos": "har/flutter.har",
   "plugin_xxx": "har/plugin_xxx.har"
   }
   }

3. 使用 Deveco Studio 配置 MyApplication 的签名

4. 运行 MyApplication
   方式二：ohos 工程 直接引用 flutter_module 源码

5. 复制 flutter_module 源码 和 flutter 相关文件
   cp -r my_flutter_module/.ohos/flutter_module MyApplication/
   mkdir -p MyApplication/flutter_module/src/main/resources/rawfile
   cp -r my_flutter_module/.ohos/flutter_module/src/main/resources/rawfile/flutter_assets MyApplication/flutter_module/src/main/resources/rawfile
   cp my_flutter_module/.ohos/har/flutter.har MyApplication/har/flutter.har

6. 修改 MyApplication/build-profile.json5
   {
   // ...
   "modules": [
   {
   "name": "entry",
   "srcPath": "./entry",
   "targets": [
   {
   "name": "default",
   "applyToProducts": [
   "default"
   ]
   }
   ]
   },
   // 以下为新增内容
   {
   "name": "flutter_module",
   "srcPath": "./flutter_module",
   "targets": [
   {
   "name": "default",
   "applyToProducts": [
   "default"
   ]
   }
   ]
   }
   ]
   }

7. 修改 MyApplication/oh-package.json5
   {
   // ...
   "dependencies": {
   "flutter_module": "./flutter_module",
   "@ohos/flutter_ohos": "./har/flutter.har"
   },
   "overrides": {
   "@ohos/flutter_ohos": "./har/flutter.har"
   }
   }

8. 使用 Deveco Studio 配置 MyApplication 的签名

9. 运行 MyApplication
