Hello everyone i am a beginner in Flutter Development, i want to use the Geolocator library to get the current location of the user, but when i tried to running the app, the build application process is failed
I have tried to set the configuration of my AndroidManifest dan the build.gradle file and i have tried to downgrade the version of the geolocator library in pubspec.yaml too, but error is still occured
here are the details of the error that I am facing :
1: Task failed with an exception.

Reset to default 2OK, I have face the same problem, i found that in android version 4.6.1 the gradle android property dont have flutter property like this:geolocation_android gradle4.6.1
but in android version 4.6.2,they change to this:geolocation_android gradle4.6.2
and the flutter geolocator auto upgrade to 4.6.2 just like flutter geolocator pubspec.yaml
so in flutter pubspec.yaml, i lock to geolocator_android version to 4.6.1 like project pubspec.yaml
and the gradle not error again
I faced this issue after upgrading Flutter from 3.24.3 and changing the old branch version of my Flutter project. I tested some versions of Geolocator, but none of them worked. I also tried updating my Gradle, but that didn’t work either. I’m not sure of the reason, but I fixed it by upgrading Flutter to the latest version, 3.29.3
After upgrading my Flutter version, the Android Studio debug button keeps getting the same Geolocator error. However, running flutter run from the command line worked. I tried invalidating caches, but there was no result. Maybe uninstalling and reinstalling could fix it.
I faced this issue; just add it to dependencies and copy the same version in your pubspec.yaml .
dependencies:
geolocator_android: 4.6.1
if you are using flutter sdk : 3.24.5 or fimilar then just downgrade geolocator_android version then it automatically solved
geolocator_android: 4.6.1
