Question

我不能同时使用这两个flutter插件：

  cloud_firestore: ^0.9.0+2
  barcode_scan: ^0.0.8

运行时发生错误：

D8: Program type already present: android.arch.core.util.Function
     *********************************************************
WARNING: This version of cloud_firestore will break your Android build if it or its dependencies aren't compatible with AndroidX.
         See https: //goo.gl /CP92wY for more information on the problem and how to fix it.
         This warning prints for all Android build failures. The real root cause of the error may be unrelated.
         *********************************************************

FAILURE: Build failed with an exception.

当我删除其中之一时，它已在Android手机上编译并运行。但是两者不能在一起。如何解决？

Answer 1

报告barcode_scan的问题，以使其针对AndroidX更新。

在新的barcode_scan版本可用之前，将插件限制为不依赖AndroidX的版本：

cloud_firestore: ^0.8.2

或手动更新barcode_scan，如 https://github.com/flutter/flutter/issues/28207#issuecomment-465600796

Answer 2

简而言之

将multidex库添加到android应用依赖项（/android/app/build.gradle）

...
android {
  ...
  defaultConfig {
    ...
    multiDexEnabled true
  }
  ...
}
...
dependencies {
  implementation 'com.android.support:multidex:1.0.3' // use latest version
  ...
}
...

在android目录下 gradel.properties文件

添加

android.useAndroidX=true
android.enableJetifier=true

似乎是运行器版本 1.2.1 引起的！

在我更改为版本 1.2.0 后，它开始工作了。

因此，我从android/app/build.gradle更改了以下行

androidTestImplementation 'androidx.test:runner:1.2.1'

到

androidTestImplementation 'androidx.test:runner: 1.2.0'

（注意：此外，不要忘记在Firebase控制台中添加要在应用程序中使用的所有 SHA证书指纹。）

Flutter：如果Cloud_firestore或其依赖项与AndroidX不兼容，Cloud_firestore将破坏您的Android构建
