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.
