【问题描述】：

我正在尝试在我的 Flutter 应用程序中使用 Google 登录。但是，由于依赖项的一些问题，我无法构建应用程序。我已将所有依赖项更新到最新版本，但无济于事。如何解决这些依赖关系以便构建应用程序？

这是一个使用谷歌登录的简单颤振应用程序，在连接的 OnePlus 6 安卓手机上运行。

我已尝试将我的依赖项更新到最新版本，并更改​​代码以匹配此处找到的 google_sign_in 依赖项的最新版本：https://pub.dartlang.org/packages/google_sign_in

我还尝试将 firebase_core 添加到依赖项列表中，因为错误消息表明该应用程序依赖于 firebase_core。这并没有改变错误消息。

项目“pubspec.yaml”依赖项

dependencies:
  flutter:
    sdk: flutter

  duration: ^2.0.0
  firebase_core: ^0.3.2
  cloud_firestore: ^0.9.11
  firebase_auth: ^0.8.4
  google_sign_in: ^4.0.1+3
  cupertino_icons: ^0.1.2

dev_dependencies:
  flutter_test:
    sdk: flutter  

项目级 build.gradle (android/build.gradle)：

buildscript 
    repositories 
        google()
        jcenter()
    

    dependencies 
        classpath 'com.android.tools.build:gradle:3.2.1'
        // Google Services class path
        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

应用级 build.gradle (android/app/build.gradle)：

apply plugin: '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 "com.example.recipe_app"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    

    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 
    implementation 'com.google.firebase:firebase-core:16.0.1'
    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'


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

'flutter run' 的输出：

Launching lib/main.dart on ONEPLUS A6003 in debug mode...

FAILURE: Build failed with an exception.

* What went wrong:
Failed to capture fingerprint of input files for task ':app:checkDebugClasspath' property 'compileClasspath' during up-to-date check.
> In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[15.0.
  1]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.

  Dependency failing: com.google.android.gms:play-services-stats:15.0.1 -> com.google.android.gms:play-services-basement@[
  15.0.1], but play-services-basement version was 16.1.0.

  The following dependencies are project dependencies that are direct or have transitive dependencies that lead to the art
  ifact with the issue.
  -- Project 'app' depends on project 'cloud_firestore' which depends onto com.google.firebase:firebase-firestore@18.2.0
  -- Project 'app' depends onto com.google.firebase:firebase-core@16.0.1
  -- Project 'app' depends on project 'firebase_auth' which depends onto com.google.firebase:firebase-auth@16.0.5
  -- Project 'app' depends on project 'google_sign_in' which depends onto com.google.android.gms:play-services-auth@16.0.1

  For extended debugging info execute Gradle from the command line with ./gradlew --info :app:assembleDebug to see the dep
  endency paths to the artifact. This error message came from the google-services Gradle plugin, report issues at https://
  github.com/google/play-services-plugins and disable by adding "googleServices  disableVersionCheck = false " to your b
  uild.gradle file.

* 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 2s
Running Gradle task 'assembleDebug'...
Running Gradle task 'assembleDebug'... Done                         2.9s

我希望应用程序能够成功构建，以便测试 Google 登录是否有效。但是，应用程序没有成功构建，我不知道该怎么办。

【参考方案1】：

我尝试使用详细模式重新编译，并被告知 AndroidX 是原因。

我遵循了link 并将所有依赖项降级到文章中列出的 AndroidX 迁移之前的版本。这解决了问题。
