Expected results

I created a new project and added this package to test it, but I cannot extract the app version.

I've been running Flutter build APK for some time while installing another package with geolocator showing this error:

Found a solution which works for me. Here's what I did:

1. went to android/settings.gradle
2. Changed the version number from "1.7.10" to "1.9.20" in the 3rd line of the following block of the code in settings.gradle file:

Before:

plugins {
    id "dev.flutter.flutter-plugin-loader" version "1.0.0"
    id "com.android.application" version "7.3.0" apply false
    id "org.jetbrains.kotlin.android" version "1.7.10" apply false
}  

After:

 plugins {
    id "dev.flutter.flutter-plugin-loader" version "1.0.0"
    id "com.android.application" version "7.3.0" apply false
    id "org.jetbrains.kotlin.android" version "1.9.20" apply false
} 

3. Went to android/build.gradle and added the following block of code at the very top of the build.gradle file:

 buildscript {
    ext.kotlin_version = '1.5.31'
}

4. ran the following commands from the project directory:

cd android
./gradlew clean
cd ..
flutter clean
flutter pub get

5. Pressed F5, and it worked.

The same problem here, I had to disable plugin by plugin to know which one was in conflict with the new version.

Hi @michaelnabil230,

Thank you for reporting this issue, I was also able to reproduce it. The workaround suggested by @nabilbndev works which is a temporary solution for now. In the meantime we will look into a more permanent solution.

[mvanbeusekom]

Hi @michaelnabil230, @nabilbndev, @hatch01,

After diving into this issue I have found the culprit. This problem is caused by the upgrade of the com.google.android.gms:play-services-location from version 21.0.1 to 21.1.0.

Apparently Google changed some dependencies in the plugin which now requires Kotlin 1.9.0 or higher. I am a bit reluctant to rollback to the old version of the com.google.android.gms:play-services-location plugin as I am hoping (need confirmation yet) that this newer version resolves some issues related to slow location fixes.

I feel it would be best to update our README with the instructions mentioned by @nabilbndev. How would you all feel about that?

[michaelnabil230]

Hi @mvanbeusekom,

From my point of view, we should not downgrade, as this will cause some problems for some users, but rather we should only update

[nabilbndev]

Hello @mvanbeusekom, It'd be better if we can get a permanent solution. Even though the temporary solution works, IMHO it makes the app a bit laggy. Would you mind checking if the temporary solution degrades app performance or not?

}

worked for me!

[fazyamir]

i tried everything mentioned in issues. only thing that worked for me was to add following lines to pubspec.yaml dependency_overrides: geolocator_android: 4.5.1

[mvanbeusekom]

Hi @michaelnabil230, @nabilbndev, @hatch01,

After some consideration we have decided to revert back to version 21.0.1 of the com.google.android.gms:play-services-location library as the new version simply isn't inline with the current stable version of Flutter.

Changes will land with PR #1463.

Also work after the > in fact, ..... on my project, thanks a lot man!

[CarlosAlvarezdev]

Sometimes the problem is in some incompatible package, the ideal thing would be to identify it and change it for a compatible version or for another package, in my case it was to change the geolocator package from version 10.0.0 to 7.0.2
