[Flutter] Android PhotoManager request permission denied (Android image permission always denied)

Problem

Android:

<uses-permission
    android:name="android.permission.READ_EXTERNAL_STORAGE"
    android:maxSdkVersion="32" />
<uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />

Flutter:

import 'package:photo_manager/photo_manager.dart';


Future<void> checkPermission() async {
  final permissionState = await PhotoManager.requestPermissionExtend();
  final hasPhotoPermission = permissionState.isAuth;
}

Code that works fine on iOS is still outputting denied on Android despite allowing image permissions

• Environment: Android Version 13

• When allowing image permissions

  • Expect: permissionState.isAuth = true

  • Actual: permissionState.isAuth = false 🥲

  • Expect: PermissionState.authorized

  • Actual: PermissionState.denied 😞😭

Notes

Reference links

• github issue) Android image library permission not working
• android developer docs) granular media permission (Android 13 or higher)
• github issue) Permission.photos.status always returns PermissionStatus.denied on Android 12

What I learned from the reference link

• Android 12, 13, and 14 have different ways of requesting access to photos.
• The biggest change is that starting with Android 13, the permission is granular instead of storage, and you write the type of media you want to request
• Starting with Android 14, you can only allow some photos.

As a result, I changed the android xml permissions back and forth, but it still came out as denied. 😞

• After looking at other cases, I realized that different OS versions request different permissions.
• So, I tried to change the photoManager options in detail based on the granularity of the problem.
  PhotoManager.requestPermissionExtend(requestOption: ...)
• The result was successful!!!!!

Fix results

Android:

<!-- SDK 32 or lower -->
<uses-permission
    android:name="android.permission.READ_EXTERNAL_STORAGE"
    android:maxSdkVersion="32" />
<!-- SDK 33 (Android13) -->
<uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />
<!-- SDK 34 (Android14) -->
<uses-permission android:name="android.permission.READ_MEDIA_VISUAL_USER_SELECTED" />

Flutter:

Future<void> checkPermission() async {
  final permissionState = await PhotoManager.requestPermissionExtend(
    requestOption: const PermissionRequestOption(
      androidPermission:
          AndroidPermission(type: RequestType.image, mediaLocation: true),
    ),
  );
  final hasPhotoPermission = permissionState.isAuth;
}

• Environment: Android Version 12, 13, 14
• When allowing image permissions
  • Expect: permissionState.isAuth = true
  • Actual: permissionState.isAuth = true 🎉
  • Expect: PermissionState.authorized
  • Actual: PermissionState.authorized 👏🥳
