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。我在使用 android{} 时遇到了类似的错误，我可以通过将apply plugin: 'com.android.application' 向上移动到 android{} 来修复它，并且它已被修复，但后来我收到了这个错误：

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

我想我必须升级另一个插件apply plugin: 'com.google.gms.google-services'。我尝试移动到第 66 行以上，但仍然遇到同样的错误。现在我在想这可能是 build.gradle 的问题，或者完全不同的东西。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。

app/build.gradle

    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

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.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'

    flutterVersionName = '1.0'
}

   def keystorePropertiesFile = rootProject.file('key.properties')
   if (keystorePropertiesFile.exists()) {
       keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
   }

似乎与your question 类似的解决方法，试试这个：

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

与以前一样，gradle system 不知道 flutter{} 方法，直到您应用 plugin/filecode。

注意

这是一种脚本语言，您可以在其中放置重要内容，逐行解释（无法引用您未告诉系统的内容）{Could not find method}。
