I haven't had any time to make this code pretty and make a PR, if anyone is able to they are welcome.

class CastMedia {

  final String contentId;
  String title;
  String subtitle;
  bool autoPlay = true;
  double position;
  String contentType;
  String streamType;
  List<String> images;
  String subtitlesUrl;

  CastMedia({
    this.contentId,
    this.title = "",
    this.subtitle = "",
    this.autoPlay = true,
    this.position = 0.0,
    this.contentType = 'video/mp4',
    this.streamType = "BUFFERED",
    this.images,
    this.subtitlesUrl = "",
  }) {
    if (null == images) {
      images = [];
    }
  }

  Map toChromeCastMap() {
    // If media doesn't have subtitles send without media->Tracks
    if (subtitlesUrl == "")
      return {
      'type': 'LOAD',
      'autoPlay': autoPlay,
