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

运行时出现错误:

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 手机上编译并运行。但两者不能并存。如何修复？

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
  ...
}
...

android目录下gradel.properties 文件

添加

android.useAndroidX=true
android.enableJetifier=true
