How to reproduce?

After requesting permission with PermissionState permisson = await PhotoManager.requestPermissionExtend(); , the permission enum always returns Permission.denied, even though I granted access.

Upon further investigation, I discovered that Huawei phones, including the one I have, require storage permission. Although Photomanager.requestPermission grants it, the return value consistently remains PermissionState.denied

What is the issue exactly? We don't know your device info yet.

@AlexV525
I tested it on a Huawei P30 with EMUI 12. When using Photomanager.requestPermission, the permission prompt is displayed, but it never receives authorization. To work around this issue, I checked for storage permission using permission_handler, which successfully granted storage permission. Consequently, I proceeded even though the Photomanager permission state remained as PermissionState.denied.

All other functionalities appear to work correctly, and I haven't encountered any additional issues. The only concern is that the PermissionState is not reflecting the actual permission status in this particular case.

[AlexV525]

Can you provide a minimal reproducible example? Or share your usage code about what permissions you've requested using the permission_handler?

[HenrikH96]

Certainly. Here's my workaround. After implementing this, I handle permission states accordingly.
The performAction boolean is used later to determine whether to navigate to AppSettings or not.

Future<PermissionState> checkPermission({bool performAction = true}) async {
    PermissionState permisson = await PhotoManager.requestPermissionExtend();
    if (permisson == PermissionState.denied) {
      //Huawei extra
      PermissionStatus storageStatus = await Permission.storage.request();
      if (storageStatus.isGranted) {
        permisson = PermissionState.authorized;
      }
    }
    
    [...]
 }

[AlexV525]

Did you declare the storage permission in your manifest? What Android API level is your Huawei device? Can it be reproduced on other devices that have the same API level?

@AlexV525,
I believe it is simply reproducible with Android 10 (API 29).

[jeevareddy]

Adding this permission resolves the permission.denied issue with Android 10
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="29"/>

@jeevareddy
Thank's that seems to fix the Issue I had with Huawei
