filesSize method

Future<BinarySize?> filesSize()

Implementation

Future<BinarySize?> filesSize() async {
  var dir = Directory(location);
  if (dir.existsSync()) {
    int totalSize = 0;
    try {
      // 列出目录下的所有文件和子目录
      await for (var entity
          in dir.list(recursive: true, followLinks: false)) {
        // 如果是文件，则获取其大小并累加
        if (entity is File) {
          totalSize += await entity.length();
        }
      }
    } catch (e) {
      logError("Error calculating size: $e");
      return null;
    }
    var size = BinarySize()..bytesCount = BigInt.from(totalSize);
    return size;
  }
  return null;
