Hi @Dzikry123,

Which version of Flutter are you using? Could you maybe include the output of the flutter doctor -v command?

Version 4.6.2 of the geolocator_android package has been updated to depend on version 3.27 or higher of the Flutter SDK, possibly you are using an older version of Flutter causing this issue.
