Error Code -2 Thrown When Attempting Local Audio Recording in Flutter

Description:
When attempting to initiate local audio recording in a Flutter application, the startRecord() method encounters error code -2. The issue arises despite the fact that other aspects of the code are functioning correctly.

My Code:

Future startRecord() async {
Directory? tempDir = await getExternalStorageDirectory();
String tempPath = tempDir!.path;

await agoraClient.engine.startAudioRecording(AudioRecordingConfiguration(
    filePath: "$tempPath/dd/rec1.acc",
    encode: false,
    fileRecordingType: AudioFileRecordingType.audioFileRecordingMic,
    quality: AudioRecordingQualityType.audioRecordingQualityLow,
    recordingChannel: 1,
    sampleRate: 16000));

}

The code provided successfully initializes local audio recording in the Flutter application.
The error occurs during the execution of the startAudioRecording method.
The error code -2 is being thrown at this point.
Expected Behavior:
The startRecord() method should be able to initiate local audio recording without encountering error code -2.

Environment Information:

Flutter version:
Agora Flutter SDK version:
Android/iOS version (if applicable):
Any other relevant environment information.
Steps to Reproduce:

Provide the necessary environment and setup details.
Execute the startRecord() method.
Observe the error code -2 being thrown.

Can you please check the path that you're using is the absolute path to the directory. Also, a quick note the getExternalStorageDirectory works only on Android and not on iOS (as mentioned in the docs: https://pub.dev/documentation/path_provider/latest/path_provider/getExternalStorageDirectory.html)
