Flutter – Unexpected file storage permission Error encounter only android 13 devices

I’m developing a Flutter app that requires storage access on Android devices. The app functions properly on Android versions up to 12, but I’m encountering storage permission issues specifically on Android 13 devices. I’ve followed the standard implementation for requesting storage permissions and have included the necessary permission declarations in the app’s AndroidManifest.xml file. However, on Android 13 devices, the app fails to access external storage and encounters permission errors.

this is my error stack:

here is my button when i clicked this error throw:

this my stopReading()

}
this is how i gave permissions

        String file = dir;

    Add these permissions to AndroidManifest.xml:

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

<uses-permission android:name="android.permission.READ_MEDIA_IMAGES"/>
<uses-permission android:name="android.permission.READ_MEDIA_VIDEO"/>
<uses-permission android:name="android.permission.READ_MEDIA_AUDIO"/>

    And set compileSdkVersion to 33.

    android {
    compileSdkVersion 33
    ...
}
