Question

我尝试实施Google对“将Firebase添加到您的应用程序”的建议更改，该更改指出：

int position = lsearch(Arr,n,val);
if (position >= 0)
{
    cout << "Item found at position " << position << endl;
}
else
{
    cout << "Item not found" << endl;
}

但是进行了这些更改（尽管已更新为当前版本，即：服务现在是4.2.0，核心现在是16.0.9），但在尝试运行应用程序时出现以下错误：

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flutter SDK中。这是我的flutter.gradle文件（摘录）：

* Error running Gradle:
ProcessException: Process "X:\Projects\Apps\Flutter\ultimate_mtg\android\gradlew.bat" exited abnormally:

FAILURE: Build failed with an exception.

* Where:
Script 'X:\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 29

* What went wrong:
A problem occurred evaluating script.
> Could not find method android() for arguments [flutter_btx813u5j2ly3w9khjl576b0k$_run_closure1@6f90a486] on project ':app' of type org.gradle.api.Project.

第29行是此行：

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.0'
    }
}

android {
    compileOptions {
        sourceCompatibility 1.8
        targetCompatibility 1.8
    }
}

有人对此有任何想法吗？我已经阅读了许多类似的主题，但没有任何建议对我有用。

有关其他信息，请访问我的\ build.gradle文件：

android {

还有我的\ app \ 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
}

找不到方法android（）作为参数... flutter.gradle问题
