Flutter OHOS 更新Flutter插件项目结构-开发者社区

更新内容

flutter插件项目中的ohos目录，将从OpenHarmony工程project结构，替换为OpenHarmony工程module结构。
flutter工程中引用的har文件，统一放到 ohos/har 目录下。
更新后需要删除ohos插件中的旧模块目录。

更新步骤

以flutter_flutter中的 integration_test 为例的更新步骤如下:

1. integration_test/ohos 目录由 project 结构修改为 module 结构

💡 注意：以下命令默认在类 Unix 环境（Linux/macOS）下运行。Windows 用户请使用 WSL 或自行适配 PowerShell 命令。

cdflutter_flutter/packages/integration_testmvohos/ohos ./ohos2rm-rfohosmvohos2 ohoscdexample flutter pub get flutter build hap--debug

执行flutter run后会出现报错，需要修改配置文件中的name字段，还需要修改 hvigorfile.ts。

2. 代码更新

2.1 修改 integration_test/ohos/oh-package.json5

修改前：

{"name":"ohos","version":"1.0.0","description":"Please describe the basic information.","main":"","author":"","license":"","dependencies": { },"devDependencies": {"@ohos/hypium":"1.0.11"} }

修改后：

{"name":"integration_test",//和插件名(pubspec.yaml中的name)保持一致"version":"1.0.0","description":"Please describe the basic information.","main":"","author":"","license":"Apache-2.0","dependencies": {"@ohos/flutter_ohos":"file:har/flutter.har", } }

2.2 修改 integration_test/ohos/src/main/module.json5

修改前：

{"module": {"name":"ohos","type":"har","deviceTypes": ["default","tablet","2in1"] } }

修改后：

{"module": {"name":"integration_test",//和插件名(pubspec.yaml中的name)保持一致"type":"har","deviceTypes": ["default","tablet","2in1"] } }

2.3 修改 integration_test/ohos/hvigorfile.ts

修改前：

import{ appTasks }from'@ohos/hvigor-ohos-plugin'; exportdefault{system: appTasks,/* Built-in plugin of Hvigor. It cannot be modified. */plugins:[]/* Custom plugin to extend the functionality of Hvigor. */}

修改后：

export{ harTasks }from'@ohos/hvigor-ohos-plugin';

检查是否可以正常运行

使用 DevEco-Studio 打开 integration_test/example, 配置签名。
使用命令运行example。

cdintegration_test/example flutter run -d$DEVICE--debug

运行OpenHarmony应用时，需要注意配置文件中 har文件的引用

引用的har文件在 ohos/har 目录下。

integration_test/example/ohos/oh-package.json5

修改后：

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

integration_test/example/ohos/entry/oh-package.json5

修改前

{//..."dependencies": {"@ohos/integration_test":"file:./har/integration_test.har", } }

修改后

{//..."dependencies": {"integration_test":"file:../har/integration_test.har", } }

可能遇到的问题

1. no such file or directory

日志信息：

hvigorERROR:ENOENT: no such file or directory, stat'xxx/flutter_flutter/packages/integration_test/ohos/build/default/cache/default/default@packageHar/ohos/oh_modules/@ohos/flutter_ohos'

解决方案：

手动删除报错信息提示的文件。

2. operation not permitted, symlink

日志信息：

hvigorERROR:ENOENT: operation not permitted, symlink'xxx/webview_flutter_ohos/ohos/webview_flutter/oh_modules/.ohpm/@ohos+flutter_ohos@file+libs+flutter.har/oh_modules/@ohos/flutter_ohos' ->'xxx/webview_flutter_ohos/ohos/build/default/cache/default/default@PackageHar/webview_flutter/oh_modules/@ohos/flutter_ohos'
