Image_picker dependency in Flutter doesn't let me compile my app with an Error message

Question

I wanted to add the image_picker library for my App registration, where the user can pick an image when he clicks on a button. My dependecies:

dependencies:
  flutter:
    sdk: flutter
  provider: ^3.2.0
  firebase_auth: ^0.15.2
  password_strength: ^0.1.2
  keyboard_avoider: ^0.1.2
  image_picker: ^0.6.2+3

Everything worked nice but after adding the image_picker in the pubspec.yaml i get the error:

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':app:preDebugBuild'.

  Android dependency 'androidx.lifecycle:lifecycle-runtime' has different version for the compile (2.0.0-rc01) and runtime (2.0.0) classpath. You should manually set the same version via DependencyResolution

Update flutter to version 1.12 which uses AndroidX by default:

https://flutter.dev/docs/development/tools/sdk/release-notes/release-notes-1.12.13#android

You can upgrade by executing the following command:

 flutter upgrade

After doing flutter upgrade, then add the sdk path to android_home:

export ANDROID_HOME="YOUR_SDK_PATH" 

Also upgrade both the android gradle in the build.gradle and the kotlin version:

dependencies {
    classpath 'com.android.tools.build:gradle:3.3.1' 
}
