open method

void open(MediaSource source, { bool autoStart = true, })

Opens a new media source into the player.

Takes a Media or Playlist to open in the player.

Starts playback itself by default. Pass autoStart: false to stop this from happening.

• Open a new Media.

player.open(
  Media.file(
    File('C:/music.ogg'),
  ),
  autoStart: false,
);

• Open a new Playlist.

player.open(
  Playlist(
    medias: [
      Media.file(
        File('C:/music.mp3'),
      ),
      Media.file(
        File('C:/audio.mp3'),
      ),
      Media.network('https://alexmercerind.github.io/music.mp3'),
    ],
  ),
);
