android - 如何修复 Android Studio 中 Flutter 的 AndroidX 兼容性？

Question

我在尝试 flutter build apk 时遇到此错误:

*******************************************************************************************
The Gradle failure may have been because of AndroidX incompatibilities in this Flutter app.
See https://flutter.dev/docs/development/packages-and-plugins/androidx-compatibility for more information on the problem and how to fix it.
*******************************************************************************************
Gradle task assembleRelease failed with exit code 1

但我可以让我的代码直接在手机或模拟器上运行...我已经使用该项目创建了 APK 文件(并将其发送到商店)。最后一个 APK 创建于 2019/07/17。从那以后，我只在列表中添加了一些数据。

我已经尝试在与上次相同的条件下进行编译:

• flutter clean等；
• 使缓存失效；
• 降级 Flutter 版本；
• 降级 Kotlin 版本；
• 降级 Gradle 版本；
• 降级 Gradle-wrapper 的分发 URL。

这是我的依赖项:

dependencies:
  flutter:
    sdk: flutter
  cloud_firestore: any
  firebase_auth: any
  google_sign_in: ^3.2.4
  flutter_datetime_picker: 1.0.7
  numberpicker: any
  flutter_svg: any
  dio: any
  path_provider: any
  firebase_messaging: any
  charts_flutter: any
  barcode_scan: 1.0.0
  unity_ads_flutter: any
  progress_indicators:

Gradle 文件:

buildscript {
    ext.kotlin_version = '1.3.31'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.2'
        classpath 'com.google.gms:google-services:4.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.2.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    implementation 'com.google.firebase:firebase-core:17.0.1'
    implementation 'com.google.firebase:firebase-auth:18.1.0'
    implementation 'com.google.firebase:firebase-messaging:19.0.1'
    implementation 'com.google.android.gms:play-services-auth:17.0.0'
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}

[编辑] 我换了电脑。可能是问题原因？

[编辑 2] 已解决

步骤:

• 升级包

dependencies:
  flutter:
    sdk: flutter
  cloud_firestore: any
  firebase_auth: any
  google_sign_in: any
  flutter_datetime_picker: 1.0.7
  numberpicker: any
  flutter_svg: any
  dio: any
  path_provider: any
  firebase_messaging: any
  charts_flutter: any
  barcode_scan: 1.0.0
  unity_ads_flutter: any
  progress_indicators:

• 复制新项目中的所有文件

看起来有些文件在传输到我的新电脑的过程中损坏或丢失了

在网上大量阅读github我发现每个人都通过升级库来解决这个问题。我发现有很多最新版本的 google_sign_in 所以尝试将 google_sign_in 升级到 4.0.6
