when i running example code for object detection on android 11. yolo-flutter-app/example. the app's only asking for camera permission. there's no asking storage permission. When i give storage permission manually the error still insist. "Error requesting permissions". I've tried using storage permission command for android 11 only in AndroidManifest.xml, like: <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> but the problem still insist

Environtment: OS: Android 11, OPPO ColorOS V11.1 Flutter Version : Flutter 3.24.3 path: ^1.9.0 path_provider: ^2.1.4 permission_handler: ^11.3.1

Behavior: What expected: Ask permission for Camera and Storage What actuak: Ask permission only for Camera and when i give storage permission manually the error still insist.

Please ensure you're using the latest version of the permission_handler package, as updates may resolve this issue. Additionally, verify that runtime permissions are requested programmatically in your code, as Android 11 requires explicit permission requests at runtime.
