找不到参数的方法android（）。。。格拉德尔问题

我尝试实施谷歌建议的“将Firebase添加到你的应用程序”更改，该更改声明：

The Google services plugin for Gradle loads the google-services.json file you just downloaded. Modify your build.gradle files to use the plugin.
Project-level build.gradle (<project>/build.gradle):

buildscript {
  dependencies {
    // Add this line
    classpath 'com.google.gms:google-services:4.0.1'
  }
}

App-level build.gradle (<project>/<app-module>/build.gradle):

dependencies {
  // Add this line
  implementation 'com.google.firebase:firebase-core:16.0.1'
}
...
// Add to the bottom of the file
apply plugin: 'com.google.gms.google-services'

在此阶段，它似乎位于颤振SDK内部。这是我的flatter.gradle文件（摘录）：

第29行是这一行：

android {

有人对这个有什么想法吗？我读过很多类似的文章，没有一条建议对我有用

有关添加的信息，请参阅my\build.gradle文件：

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.0'
        classpath 'com.google.gms:google-services:4.2.0'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    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'

感谢您的回复，@Nuts，可能是重复的，但这与我无关。正如人们在所有这些线程中建议的那样，我的android{}块位于\app\build.gradle中，而不是位于\build.gradle中。不幸的是，这条线对我没有帮助。
