【问题描述】：

project/build.gradle

应用插件：'com.android.application'

dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'
    classpath 'com.google.gms:google-services:4.3.2'
}

在 app/build.gradle 中

第 24 行应用插件：'com.android.application'

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

android {
    compileSdkVersion 28

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "blablabla.com"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.firebase:firebase-analytics:17.2.0'
}

apply plugin: 'com.google.gms.google-services'

在 pubspec.yaml 中

dependencies:
  flutter:
    sdk: flutter
  firebase_database: ^2.0.2
  firebase_core: ^0.3.1+1
  timeago: ^2.0.10

我收到此错误

如何解决这个错误...???

【问题讨论】：

我建议您将项目迁移到 AndroidX 并重试

标签： flutter firebase-realtime-database dart build.gradle flutter-dependencies

【解决方案1】：

凹凸依赖版本：

classpath 'com.android.tools.build:gradle:3.5.2'
classpath 'com.google.gms:google-services:4.3.3'

  firebase_database: ^3.1.0
  firebase_core: ^0.4.2+1

在 app/build.gradle 中添加这些：

android {
    ...

    defaultConfig {
        ...
        multiDexEnabled true // add this
    }
}

dependencies {
    ...
    implementation 'com.android.support:multidex:1.0.3' // add this
}

不要忘记在 app/ 文件夹中创建 google-services.json 文件并用您的数据 (docs link) 或使用一些模拟 (如 this one) 填充它：

{
  "project_info": {...},
  "client": [...],
}
