鸿蒙harmonyos next flutter混合开发之ohos工程引用 har 文件

• 创建鸿蒙原生工程MyApplication。
• 创建flutter  module，生成har文件，并且将flutter  module中.ohos文件entryability/EntryAbility.ets、pages/Index.ets分别替换MyApplication中的。

# 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

• 将上一步生成的har文件拷贝到原生工程中MyApplication/har/

cp -r my_flutter_module/.ohos/har/* MyApplication/har/

• 修改原生工程MyApplication/oh-package.json5，

{"dependencies": {"@ohos/flutter_module": "./har/flutter_module.har","@ohos/flutter_ohos": "file:./har/flutter.har"},"overrides": {"@ohos/flutter_ohos": "file:./har/flutter.har"}
}

• 对原生工程MyApplication进行签名
• 运行 MyApplication
