Can't multiple select when type: FileType.audio

[yunchiri]

                    FilePickerResult? result = await FilePicker.platform
                        .pickFiles(allowMultiple: true, type: FileType.audio);

only one sound file can pick

                    FilePickerResult? result = await FilePicker.platform
                        .pickFiles( type: FileType.audio);
