Custom ringtone is not working

[AlertnowMobile]

Hi @hiennguyen92,

In my app, I've added custom wake-up call ringtones. However, it always plays the phone's default ringtone instead of the custom one.

I placed my ringtones in the following locations:

• Android: android/app/src/main/res/raw
• iOS: ios/Runner/high_ring.caf

But it’s still not working. Here’s the code I’m using:

Future<void> showCallkitIncoming(String uuid, String title) async {
  // sample high_ring
  final String ringtone = await getRingtonePreference();

  await FlutterCallkitIncoming.showCallkitIncoming(CallKitParams(
    id: uuid,
    nameCaller: title,
    appName: 'Xyz',
    avatar: 'assets/images/logo.jpeg',
    type: 0,
    duration: 30000,
    textAccept: 'Accept',
    textDecline: 'Decline',
    missedCallNotification: const NotificationParams(
      showNotification: false,
      isShowCallback: false,
      subtitle: 'Missed call',
      callbackText: 'Call back',
    ),
    android: AndroidParams(
      isCustomNotification: false,
      isCustomSmallExNotification: false,
      isShowLogo: false,
      ringtonePath: ringtone,
      backgroundColor: '#FFFFFF',
      actionColor: '#4CAF50',
      textColor: '#000000',
      isShowFullLockedScreen: true,
    ),
    ios: IOSParams(
      iconName: 'AlertNow',
      handleType: 'number',
      supportsVideo: true,
      maximumCallGroups: 2,
      maximumCallsPerCallGroup: 1,
      audioSessionMode: 'default',
      audioSessionActive: true,
      audioSessionPreferredSampleRate: 44100.0,
      audioSessionPreferredIOBufferDuration: 0.005,
      supportsDTMF: true,
      supportsHolding: true,
      supportsGrouping: false,
      supportsUngrouping: false,
      ringtonePath: '$ringtone.caf',
    ),
  ));
}

Could you help me identify if anything is wrong here? Thank you so much!
