pickAudio method

Future<String?> pickAudio({
  1. List<String>? exts,
})

目前仅支持mp3试试

Implementation

Future<String?> pickAudio({List<String>? exts}) async {
  final result = await FilePicker.platform.pickFiles(
      type: exts == null ? FileType.audio : FileType.custom,
      allowCompression: true,
      allowedExtensions: exts);
  if (result == null) {
    return null;
  }
  final f = result.files.first;
  return f.path;
}
