Failed to resolve variable '${animal.sniffer.version}' when migrate to AndroidX

Question

I\'m using Android Studio 3.2 Beta5 to migrate my project to AndroidX. When I rebuild my app I got these errors:

ERROR: [TA

Answer 1

Android version: 4.10.2

I solved this issue with three simple steps: First i added below this in pubspec.yml: (with two spaces of identation)

module:
  androidX: true 

Adding this two lines below in gradle.properties, i have this in android/gradle.properties, in the project folder.

android.useAndroidX=true
android.enableJetifier=true

And after this i wrote with the terminal:

flutter clean

Maybe you will have to stop the device and run again.
