Is this a one time issue?
Are you able to use plugin otherwise?

[Leadrive]

on the example, in the left area, I add a network file.
https://www.leadrive.cn/bee.mp4
after it play over, it will cause this error.
and it will loop playback, and the error will cause again.

Thankyou for report.

@Leadrive

this.player?.open(
  new Playlist(
      medias: this.medias,
      playlistMode:
          PlaylistMode.loop),
);

Use the playlistMode.single

It is played again because in the demo there is a playlistMode.loop. I am going to further check the minimum and maximum error.

[DomingoMG]

Ok I know why it is, it is returning a value outside the range of the slider, I am going to do a pull request that solves the problem.

[DomingoMG]

@alexmercerind, @Leadrive
It should be fixing with my latest changes applied to the master branch

open, play, open, play..... maybe about 5 or 6 times.
the bug will caused.
Please check it.

[DomingoMG]

@Leadrive
I will check it again.
But the error is due to the total length of the video, it seems to return null, I'll see what I can do.

[StarSkyGeminid]

Is this bug solved?
