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

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

当运行时，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.

当我删除其中一个时，

它在 Android phone 上编译并运行ned。但两者不能并存。如何修复？

Answer 1

报告 barcode_scan 的问题以针对 AndroidX 进行更新。

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

cloud_firestore: ^0.8.2

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

似乎 runner 版本 1.2.1 对此负责！

在我更改为 1.2.0 版本后，它起作用了。

所以，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：另外，不要忘记在 Firebase 控制台中添加您要在应用中使用的所有 SHA 证书指纹。）

Answer 3

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
