应用插件时出现错误："com.huawei.agconnect" in Flutter

Question

我试图在flutter中使用华为SDK，所以我在android/app/build.gradle文件，如中的说明所示https://developer.huawei.com/consumer/en/doc/development/HMS-Plugin-Guides/integrate-plugin-0000001050418527

apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
**apply plugin: 'com.huawei.agconnect'**

然而，它返回时出现错误：

FAILURE: Build failed with an exception.
* What went wrong:
Could not determine the dependencies of task ':app_settings:compileDebugAidl'.
> Failed to find Platform SDK with path: platforms;android-R

我看到了一些解决方案，其中指出需要在android/build.gradle文件中添加以下代码

subprojects {
project.evaluationDependsOn(':app')
}
subprojects {
project.buildDir = "${rootProject.buildDir}/${project.name}"
project.evaluationDependsOn(':app')
afterEvaluate {project ->
if (project.hasProperty("android") && project.property("android").compileSdkVersion.equals("android-R")) {
android {
compileSdkVersion 30
}
}
}
}

我已经添加了它，但它仍然返回相同的错误。当我删除应用插件"com.huawei.agconnect">时，没有出现错误。但在这种情况下，我想使用插件，因为我正计划使用华为推送套件。

请告诉我是否需要任何额外的信息来解决这个问题。非常感谢。

与这里的github问题一样，错误很可能是由您使用的Android SDK版本引起的。华为Flutter推送套件建议您使用Android SDK 10.0(API 29级(或9.0(API 28级(版本。您可以通过导航到文件>从Android Studio下载这些版本；设置>安卓SDK>SDK平台菜单。

对于build.gradle，您可以将您的gradle文件与华为Flutter Push Kit-Demo中提供的文件进行比较，并进行必要的更改。为了方便起见，我将build.gradle文件留给huawei_push:5.0.2+301。

注意：如果这些操作不能解决错误，请向github存储库提交一个问题，并附上flutter医生输出、渐变文件和再现错误的最小代码样本。
