flutter App 添加 Facebook 身份验证时出错

Question

我快要疯了，因为三天前我就想解决这个问题:)任何人都可以帮助我。 注意：该应用程序已在 Google Play 上发布，现在我正在开发应用程序的第 2 版。

我正在尝试将 Facebook 身份验证添加到现有的 flutter 应用程序中，我将包添加到 pubspec.yaml 文件中，并从官方文档中进行所有配置。 现在，当尝试调试其显示错误时：

Execution failed for task ':flutter_facebook_auth:compileDebugJavaWithJavac'.
> Could not resolve all files for configuration ':flutter_facebook_auth:debugCompileClasspath'.
   > Could not find lifecycle-common-2.3.0.jar (androidx.lifecycle:lifecycle-common:2.3.0).
     Searched in the following locations:
         https://dl.google.com/dl/android/maven2/androidx/lifecycle/lifecycle-common/2.3.0/lifecycle-common-2.3.0.jar

这是有关项目的一些详细信息：

Flutter pubspec.yaml 文件：

name: red_gold
description: A new Flutter project.

# The following line prevents the package from being accidentally published to
# pub.dev using `pub publish`. This is preferred for private packages.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.

# For information on the generic Dart part of this file, see the

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
   - assets/images/

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.dev/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  fonts:
   - family: ACaslon Bold
     fonts:
       - asset: assets/fonts/ACaslonPro-Bold.otf
       - asset: assets/fonts/ACaslonPro-BoldItalic.otf
         style: italic
   - family: Acaslon SemiBold
     fonts:
       - asset: assets/fonts/ACaslonPro-SemiBold.otf
       - asset: assets/fonts/ACaslonPro-SemiBoldItalic.otf
         style: italic
   - family: Acaslon Regular
     fonts:
       - asset: assets/fonts/ACaslonPro-Regular.otf

  # For details regarding fonts from package dependencies,
  # see https://flutter.dev/custom-fonts/#from-packages

这是来自我的应用程序/构建.gradle 文件：

 minSdkVersion 19
        targetSdkVersion 30

来自 android/build/gradle：

buildscript {
    repositories {
        google()
        mavenCentral()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.10"
        classpath 'com.android.support:multidex:1.0.3'


    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

尝试将 maven { url 'https://maven.google.com' } 添加到您的构建脚本存储库：

 repositories {
        jcenter()
        maven { url 'https://maven.google.com' }
        google()
    }
