# 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 --local-engine=/Users/xxx/ohos/src/out/ohos_debug_unopt_arm64 --debug
cd -
# 3. 复制.ohos内 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

1. 复制 flutter_module.har
cp my_flutter_module/.ohos/flutter_module/build/default/outputs/default/flutter_module.har MyApplication/har/flutter_module.har

2. 修改 MyApplication/entry/oh-package.json5
{
// ...
"dependencies": {
"[@ohos](/user/ohos)/flutter_module": "../har/flutter_module.har"
}
}
3. 使用 Deveco Studio 配置 MyApplication 的签名
4. 运行 MyApplication
