FilePicker extension Flutter problem with audio types

[faci]

Describe the bug I use the file_picker package (last actual version : 8.0.6) to get audio files on IOS. It works pretty well, but just not on the first load.. On the first load, it asks for apple music access and than when I select a file, the bytes attribute is empty. When I close and re-open it works.

Platform

• [ ] Android
• [x] iOS
• [ ] Web
• [ ] Desktop

Platform OS version IOS 17.5.1 -> I had the same problem in the previous versions

How are you picking?

  // Opens the file explorer of the device,
  static Future<FilePickerResult?> getFilePickerFromDevice() async {
    return await FilePicker.platform.pickFiles(
      withData: true,
      type: FileType.audio,
      allowMultiple: false,
      allowCompression: true,
    );
  }
}

I have the authorizations on the info.plist !

<key>NSAppleMusicUsageDescription</key>
<string>Autorisez l'accès à votre musique pour pouvoir la partager.</string>

And I tried to add PERMISSION_MEDIA_LIBRARY in the Podfile

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0.0'
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
        '$(inherited)',
        'PERMISSION_PHOTOS=1',
        'BYPASS_PERMISSION_LOCATION_ALWAYS=1',
        'PERMISSION_MEDIA_LIBRARY=0'
      ]
    end
  end
end

Details to reproduce the issue Just call the code above ! Make sure you didn't accept the apple music before.

Error Log returned value on the first selection: FilePickerResult(files: [PlatformFile(path /private/var/mobile/Containers/Data/Application/356AB0F5-BFFC-4CE6-82FC-CF94BA1070E9/tmp/Danyl - Billie Eilish (clip officiel).m4a, name: Danyl - Billie Eilish (clip officiel).m4a, bytes: null, readStream: null, size: 0)])

error: (-11850) Opération interrompue

More details When I use a FileType.custom and define the types of music I accept, it works, but it opens the normal file storage, while I really need to open apple Music selector, since the app I'm developing is mainly focus on music.

I hope you have enough informations ! And the bug is clear ! thank you :)

For your info on this issue, the problem seemed to come from FileType: Audio on the filePicker package ! So I just changed to custom. But I believe it's too bad, because that would be nice to be able to use this option on IOS and it works everytime ^^
