Flutter: Cloud_firestore will break your Android build if it or its dependencies aren't compatible with AndroidX

问题

I can not use these both flutter plugins together:

  cloud_firestore: ^0.9.0+2
  barcode_scan: ^0.0.8

When run, error occured:

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.

it compiled and runned on Android phone when I remove one of them. But both can not go together. How to fix?

回答1:

In short

Add multidex library to android app dependency (/android/app/build.gradle)

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

under android directory gradel.properties file

Add

android.useAndroidX=true
android.enableJetifier=true

Found the solution (for me, at least) !

I had the following issue:

It seems that runner version 1.2.1 was the responsible for this !

After I changed to version 1.2.0 it worked.

So, I changed the following line from android/app/build.gradle

androidTestImplementation 'androidx.test:runner:1.2.1'

androidTestImplementation 'androidx.test:runner: 1.2.0'

(Note: Also, don't forget to add in Firebase Console all SHA certificate fingerprints you are going to use in your apps.)

回答3:

Report an issue with barcode_scan to have it updated for AndroidX.

Limit the plugin to a version that does not depend on AndroidX until a new barcode_scan version becomes available:

cloud_firestore: ^0.8.2

Or update barcode_scan manually like mentioned in https://github.com/flutter/flutter/issues/28207#issuecomment-465600796
