android - 在 Visual Studio Code 中找不到参数的方法 flutter()

Question

所以我目前正在尝试为 Google Play 商店构建我的应用程序的 apk。我在 android{} 上遇到了类似的错误，我可以通过将 apply plugin: 'com.android.application' 移到 android{} 上方来修复它，但后来我得到了这个错误:

FAILURE: Build failed with an exception.

* Where:
Build file '/Users/herb/Downloads/morningly/android/app/build.gradle' line: 66

* What went wrong:
A problem occurred evaluating project ':app'.
> Could not find method flutter() for arguments [build_4k00465lacv9h9hnlvfrbb5oa$_run_closure3@26ab5c57] on project ':app' of type org.gradle.api.Project.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 0s

我想我必须移动另一个插件 apply plugin: 'com.google.gms.google-services'。我试着移动到第 66 行以上，但我仍然遇到同样的错误。现在我在想这可能是 build.gradle 的问题，也可能是完全不同的问题。请，如果您对如何提供帮助有任何见解，请随时发表评论。我非常想上传我的应用程序。

    }

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

与 your question 类似的解决方法看来，试试这个:

 apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

在您应用 plugin/filecode 之前，flutter{} 方法对 gradle 系统 是未知的。

注意

这是一种脚本语言，你把事情放在那里，逐行解释(不能引用你没有告诉系统的东西){Could not find method}。
