鸿蒙版Flutter开发相关
申请权限相关问题
解决方案：
应用需要在module.json5配置文件的requestPermissions标签中声明权限，配置权限后重新签名。
flutter输入框长按无法粘贴问题
应用需要申请剪贴板权限ohos.permission.READ_PASTEBOARD。
"requestPermissions": [
{
"name": "ohos.permission.READ_PASTEBOARD",
"reason": "$string:EntryAbility_desc",
"usedScene": {
"abilities": [
"EntryAbility"
],
"when": "inuse"
}
}
]
通知 注意：您正在申请受限的 ACL 权限：WRITE_IMAGEVIDEO、READ_PASTEBOARD。这些权限将与您的应用发布一起接受审核。为了加快审核流程，请申请以下权限（如果它们足以满足您的目的）：SaveButton、PasteButton。权限应用场景不要再询问。
flutter无法保存图片到相册问题
应用需要申请保存图片权限ohos.permission.WRITE_IMAGEVIDEO。
"requestPermissions": [
{
"name": "ohos.permission.WRITE_IMAGEVIDEO",
"reason": "$string:EntryAbility_desc",
"usedScene": {
"abilities": [
"EntryAbility"
],
"when": "inuse"
}
}
]
和上面一样，需要发邮件申请，调试的话，可以临时解决。
dart代码中判断当前平台是否是ohos
import 'package:flutter/foundation.dart';
bool isOhos() {
return TargetPlatform == TargetPlatform.ohos;
}
所以你会了吗？

解决办法：
flutter config --ohos-sdk=/Users/jianguo/Library/OpenHarmony/Sdk
flutter config --ohos-sdk=""
这两个命令换着来
