i give the permission also

NSMicrophoneUsageDescription
Can We Use Your Microphone Please

This is my function

void _initRecorder() async {
if (await AnotherAudioRecorder.hasPermissions) {
String customPath = chatId;
Directory appDocDirectory;
if (Platform.isIOS) {
appDocDirectory = await getApplicationDocumentsDirectory();
} else {
appDocDirectory = (await getExternalStorageDirectory())!;
}
customPath = appDocDirectory.path + customPath + DateTime.now().millisecondsSinceEpoch.toString();

  _recorder = AnotherAudioRecorder(customPath, audioFormat: AudioFormat.WAV);
  await _recorder?.initialized;
} else {
  print("Permissions not granted");
}

}

this is how i used this

                          GestureDetector(
                            onTap: () {
                              if (newMessageController.text.isEmpty) return;
                              if (group) {
                                sendGroupMessage();
                              } else {
                                sendMessage();
                              }
                            },
                            onLongPress: () async {
                              if (newMessageController.text.isEmpty) {
                                animationController
                                  ..forward()
                                  ..repeat(reverse: true);
                                await _recorder?.start();
                              }
                              print('onLongPress');
                            },
                            onLongPressEnd: (details) {
                              animationController.stop();
                              animationController.reset();
                              stopRecording();
                              print('onLongPressEnd');
                            },
                            child: AnimatedBuilder(
                              animation: animationController,
                              builder: (context, child) {
                                return Transform.scale(
                                  scale: 1 + animationController.value * 0.5,
                                  // Adjust the scale factor as needed

                                );
                              },
                              child: SizedBox(
                                height: 45,
