[ariG23498]

i have the same error, any updates on that?

[momoDragon]

no idea fam. Hope this gets fixed asap.

@momoDragon, @ariG23498, have you already tried the latest version (3.0.0)?

It looks like you have (partly) updated your project to support AndroidX (compileSdkVersion 28). Version 2.1.1 of the plugin does not support AndroidX which has been resolved in version 3.0.0.

[althex2015]

Same problem here.

Is there anyway use back version 2.1.1 or non support AndroidX version?
I using flutter_facebook_login plugin not support AndroidX yet, i can't move project to AndroidX
The other Plugin able to downgrade, but only geolocator got issue.

Please help me~ Thanks

[momoDragon]

i think migrating to androidX and using the latest plugin worked for me. if u guys have issue migrating u can follow this very straight to the point guide https://medium.com/@swhussain110/how-to-migrate-your-flutter-app-to-androidx-9a78eaaa924b

[mvanbeusekom]

@althex2015, yes you can. To do so you need to add the following libraries to your pubspec.yaml with the specific version numbers (these are the versions just before the AndroidX migration):

  google_api_availability 1.0.4
  permission_handler: 2.1.2
  geolocator 2.1.1

[mvanbeusekom]

@momoDragon good to hear it worked for you, I will close this issue now (thank you for providing the link).

For other people the TL;DR version is:

1. Add the following to your "gradle.properties" file:

android.useAndroidX=true
android.enableJetifier=true

1. Make sure you set the compileSdkVersion in your "android/app/build.gradle" file to 28:

android {
  compileSdkVersion 28

  ...
}

1. Make sure you replace all the android. dependencies to their AndroidX counterparts (a full list can be found here: https://developer.android.com/jetpack/androidx/migrate).

It's work, thanks a lot
