HarmonyOS Flutter在pubspec.yaml添加webview\_flutter后执行flutter pub get报错了？

Question

在pubspec.yaml文件中添加webview\_flutter依赖项。

webview_flutter:
    git:
    url: "https://gitee.com/openharmony-sig/flutter_packages.git"
    path: "packages/webview_flutter/webview_flutter"

执行指令：

flutter build har --local-engine=/Users/rickli/Documents/Work/HM/12/src/out/ohos_release_arm64 --release 

输出报错log：

https://gitee.com/openharmony-sig/flutter\_packages/blob/master/packages/webview\_flutter-v4.4.4/webview\_flutter/pubspec.yaml

参照这个试试，这边执行flutter pub get正常。
