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

Question

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?

Answer 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
