Question

我正在尝试通过Flutter应用程序使用Google登录。但是，由于某些依赖关系问题，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？

这是一个简单的flutter应用程序，它使用google登录在已连接的OnePlus 6 android手机上运行。

我尝试将依赖项更新为最新版本，并更改代码以匹配在此处找到的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

Project Level 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
}

应用程序级别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：

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

我希望该应用程序能够成功构建，因此我可以测试Google登录是否正常工作。但是，该应用程序无法成功构建，我不知所措。

Answer 1

我尝试使用详细模式重新编译，并被告知AndroidX是原因。

我遵循了此link，并将所有依赖项降级为本文中列出的AndroidX迁移之前的版本。这解决了这个问题。
