Your question

I suddenly encountered an issue on parts of my code calling isGranted. The only change I remember prior to getting this error is upgrading my Android Studio. Currently, I'm able to build if I remove the caret in the pubspec.yaml from permission_handler: ^11.0.1 to permission_handler: 11.0.1. If I use ^11.0.1, it will point to permission_handler-11.3.1\lib\permission_handler.dart and the error below will appear. Can anyone advice please? Btw, I tried open the same flutter project on another Windows device and it doesn't have this issue.

A member named 'isGranted' is defined in extension 'PermissionCheckShortcuts' and extension 'PermissionStatusGetters', and none are more specific.
Try using an extension override to specify the extension you want to be chosen.

This is how I import and part of the affected code:-

import 'package:permission_handler/permission_handler.dart' as permission;
...
await permission.Permission.locationWhenInUse.isGranted;

Version

^11.0.1

Hi @ksyeoh,

Thank you for submitting this issue. Unfortunately I cannot reproduce the error and we have not done any recent upgrades ourselves. Version 11.3.1 was released 49 days ago.

The PermissionStatusGetters and PermissionCheckShortcuts have been added to the code base 4 years ago and are both extensions on different enums. The PermissionStatusGetters are an extension on the PermissionStatus enum, while the PermissionCheckShortcuts extend the Permission enum:

See definitions here:

Possibly Android Studio is confused some how, could you try the following:

Remove all the permission_handler related packages from the local cache.
Run flutter clean in the root of your project.
Invalidates caches in Android Studio:
- Open Android Studio
- Select "File" from the top menu
- Select "Invalidate caches..."

As mentioned I have tried to reproduce the error using the "Example" application with my copy of Android Studio and experienced no problem. The application compiled and ran without any problems on my Android Pixel 7a device. Here are some details on my environment:
