[不是Harmony ArkUI 不会写，而是 Flutter 更有性价比 - 掘金 (juejin.cn)](https://juejin.cn/post/7329110277172985908)
## 前言
[Harmony生态势如破竹，已有超4000应用加入，实现垂域全覆盖](https://mp.weixin.qq.com/s?__biz=MjM5NTE4NzU4MQ==\&mid=2652159181\&idx=1\&sn=7cc9962cdd71429277b2fb780ec43031\&chksm=bd1c42df8a6bcbc90566de2e8a06b06bd7dd29a54e2d4ca9374b12e7a67de5fe2b2361d58c74\&mpshare=1\&scene=23\&srcid=0407a8b3OsMB6BKWGBONPgI5\&sharer_shareinfo=b4a2b6e55491da56bb5dbc6e096aa835\&sharer_shareinfo_first=491946d8b1533dc330be8a9db3856ae9#rd)，商店里面的Harmony `app` 也越来越多，就像余总说的一样，
> 在一起，就可以 ！
[OpenHarmony-SIG/flutter\_flutter (gitee.com)](https://gitee.com/openharmony-sig/flutter_flutter) 社区一直在致力于使用 Flutter 更加快速地适配Harmony平台。
而距离 [不是Harmony ArkUI 不会写，而是 Flutter 更有性价比 - 掘金 (juejin.cn)](https://juejin.cn/post/7329110277172985908) 已经有一段时间了，我们来看看 `Flutter` Harmony化的进展如何了。
> 重要提示，Flutter Harmony化，需要华为提供的真机和最新的SDK或者自己申请了开发者预览 Beta 招募，没有的，暂时不要尝试。
最近 [华为纯血Harmony HarmonyOS NEXT 开发者预览版首批 Beta 招募开启，支持 Mate 60 / Pro、X5 机型](https://www.ithome.com/0/745/256.htm)， 这给一些个人开发者提前体验Harmony `NEXT` 的机会。
> 后续内容全部基于 [OpenHarmony-SIG/flutter\_flutter (gitee.com)](https://gitee.com/openharmony-sig/flutter_flutter) 和 [OpenHarmony-SIG/flutter\_engine (gitee.com)](https://gitee.com/openharmony-sig/flutter_engine) 的 **dev** 分支。参考文档也以 **dev** 分支 的文档为准。另外最新支持的是 `ohos api11` 。
## 插件进度
现阶段 `Flutter` 适配工作主要集中在Harmony原生插件的适配。下面介绍一下已知完成适配的插件。
### flutter\_packages
[OpenHarmony-SIG/flutter\_packages (gitee.com)](https://gitee.com/openharmony-sig/flutter_packages) 是适配官方 [flutter/packages: A collection of useful packages maintained by the Flutter team (github.com)](https://github.com/flutter/packages/) 仓库。

一些注意事项
关于Harmony的 context
在制作插件中，你可能需要用到 2 种 context。
ApplicationContex
你可以直接从 onAttachedToEngine 方法中获取。
private context: Context | null = null;
onAttachedToEngine(binding: FlutterPluginBinding): void {
this.context = binding.getApplicationContext();
}
onDetachedFromEngine(binding: FlutterPluginBinding): void {
this.context = null;
}
该 context 可以用于获取 applicationInfo 等属性。
let applicationInfo = this.context.applicationInfo;
UIAbilityContext
插件继承 AbilityAware 并且在 onAttachedToAbility 方法中获取。
export default class XXXPlugin implements FlutterPlugin, MethodCallHandler, AbilityAware {
private _uiContext: common.UIAbilityContext | null = null;
onAttachedToAbility(binding: AbilityPluginBinding): void {
this._uiContext = binding.getAbility().context;
}
onDetachedFromAbility(): void {
this._uiContext = null;
}
}
该 uiContext 可以用于获取 applicationInfo 等属性。
photoAccessHelper.getPhotoAccessHelper(PhotoManagerPlugin.uiContext);
关于插件参数传递
按照以前的习惯，dart 端传递 map 参数，原生端根据 map 解析参数。
但由于 ts 支持将字符串直接转换成对应的 interface ，那么我们可以将 dart 的端的参数。
参数定义
比如 geolocator_ohos 中的 CurrentLocationSettingsOhos 在 dart 端的实现为如下:
Map<String, dynamic> toMap() {
return {
if (priority != null) 'priority': priority?.toInt(),
if (scenario != null) 'scenario': scenario?.toInt(),
if (maxAccuracy != null) 'maxAccuracy': maxAccuracy,
if (timeoutMs != null) 'timeoutMs': timeoutMs,
};
}
@override
String toString() {
return jsonEncode(toMap());
}
而在Harmony原生端，对于的 interface 是 CurrentLocationRequest
export interface CurrentLocationRequest {
priority?: LocationRequestPriority;
scenario?: LocationRequestScenario;
maxAccuracy?: number;
timeoutMs?: number;
}
值得注意的是，如果参数为 null，不要传递过去，比如 'priority': null , 如果传递过去，Harmony原生端会解析错误。不传递过去的话，会解析为 undefined，这也对应了 priority?: LocationRequestPriority 可选的意思。
可以使用 chatgpt 直接将Harmony的 interface 转换成 dart 的类，并且增加 toMap，fromMap，和注释。
插件传递
dart 端，将参数类以字符串的方式传递过去，并且用字符串的方式接受返回值。
@override
Future<Position> getCurrentPosition({
LocationSettings? locationSettings,
String? requestId,
}) async {
assert(
locationSettings == null ||
locationSettings is CurrentLocationSettingsOhos,
'locationSettings should be CurrentLocationSettingsOhos',
);
try {
final Duration? timeLimit = locationSettings?.timeLimit;
Future<dynamic> positionFuture =
GeolocatorOhos._methodChannel.invokeMethod(
'getCurrentPosition',
locationSettings?.toString(),
);
if (timeLimit != null) {
positionFuture = positionFuture.timeout(timeLimit);
}
return PositionOhos.fromString(await positionFuture);
}
}
在Harmony端, 将字符串直接转换成Harmony对应的 interface 。
let request: geoLocationManager.CurrentLocationRequest = JSON.parse(args);
并且将要返回的 interface 转换成字符串。
result.success(JSON.stringify(location));
当然了，这样有个问题，就是如果Harmony端修改了 interface 的属性名字，插件很难感知到(当然会报错)。
关于做 Flutter Harmony化的一些环境要求
重要提示，Flutter Harmony化，需要华为提供的真机和最新的SDK或者自己申请了开发者预览 Beta 招募，没有的，暂时不要尝试。

说点其他
关于 Google 裁员
最近很多人都在问，传着传着就变成 Google 要解散 Flutter 团队。不管是哪个公司都会有裁员的哪一天，与其犹豫不决，还不如笃定前行。
总有人年轻
没有人永远年轻，但总有人年轻。最近 NBA 季后赛，你不得不承认，他们都老了。过年的时候出去玩，把娃放肩膀上面驮着，脖子肩膀酸痛了，2天才恢复。有那么一刻，确实感觉自己也不再年轻了。
尽管时间会在我们身上留下痕迹，但当我们投身于自己热爱的事业或兴趣时，心态和精神永远年轻。
扶我起来，我还能写代码。那你，是什么时候发现自己不再年轻的？
