Implementation

@override
Future<String?> convertAmrToWav(String amrPath, {int sampleRate = 22050}) async {
  try {
    final result = await methodChannel.invokeMethod('convertAmrToWav', {
      'amrPath': amrPath,
      'sampleRate': sampleRate,
    });
    return result as String?;
  } catch (e) {
    if (kDebugMode) {
      print('convertAmrToWav error: $e');
    }
    return null;
