正在获取D8：程序类型已存在：com.google.android.gms.internal.measurement.zzfe

Question

我正在获得 D8：当我添加 firebase_admob 客栈时，程序类型已经存在：com.google.android.gms.internal.measurement.zzfe 。

如果我添加了Google Play服务版本，则该应用一开始就崩溃了。我曾尝试降级该版本，但无法正常工作。

这是我的pubspec.yaml-

名称：******     描述：一个新的Flutter项目。

<dependency>
   <groupId>com.print.assess</groupId>
   <artifactId>mns.pro</artifaxtId>
   <version>2.0</version>
 </dependency>

这是我的build.gradle-

environment:
  sdk: '>=2.0.0-dev.68.0 <3.0.0'

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: 
  photo_view: ^0.2.2
  cloud_firestore: ^0.9.7
  firebase_admob: ^0.8.0+3
  share: ^0.6.0+1
  permission_handler: ^3.0.0

dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_launcher_icons: 

flutter_icons:
  android: true
  ios: true
  image_path: 'assets/icon/app_icon.png'
  adaptive_icon_background: '#FFFAFAFA'
  adaptive_icon_foreground: 'assets/icon/app_icon.png'

      assets:
        - assets/rangoli_loader.gif
      fonts:
        - family: Raleway
          fonts:
            - asset: assets/fonts/Raleway-Regular.ttf

这是我的app / build.gradle-

    buildscript {
        repositories {
            google()
            jcenter()
        }

        dependencies {
            classpath 'com.android.tools.build:gradle:3.3.0'
            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
    }
