Future<String?> getDownloadPath() async {
    Directory? directory;
    try {
      if (Platform.isIOS) {
        directory = await getApplicationDocumentsDirectory();
      } else {
        directory = Directory('/storage/emulated/0/Download');
        // Put file in global download folder, if for an unknown reason it didn't exist, we fallback
        // ignore: avoid_slow_async_io
        if (!await directory.exists()) directory = await getExternalStorageDirectory();
      }
    } catch (err, stack) {
      print("Cannot get download folder path");
    }
    return directory?.path;
  }
  • 在IOS系统中，它创建了一个带有你的应用程序名称的文件夹，并将文件放在里面
  • 在安卓系统上，使用/storage/emulated/0/Download 这个目录
