MediaInfo duration is integer not double

[hyobbb]

Hi. I am using video_compress: ^2.1.0 and on running "compressVideo" function it returns MediaInfo instance.

class MediaInfo {
  String path;
  String title;
  String author;
  int width;
  int height;

  /// [Android] API level 17
  int orientation;

  /// bytes
  int filesize; // filesize
  /// microsecond
  double duration;
  bool isCancel;
  File file;

  MediaInfo({
    @required this.path,
    this.title,
    this.author,
    this.width,
    this.height,
    this.orientation,
    this.filesize,
    this.duration,
    this.isCancel,
    this.file,
  });

in this class it says that it returns duration as double/microsecond
but when I upload the video on firebase parsing those data it seems that it returns duration as integer with millisecond unit.
could you check if is it a bug?
