@nateclicks I reported a similar thing here #107779 a while back. |

It is similar. I wasn't having issues with .mp4 files though. Mine was limited to HLS (m3u8) streams. But I only tested an MP4 on iOS. It looks like you weren't having the issue there either. |

When using an HLS stream as the network source, a listener added to the video controller gets fired multiple times for the, seemingly, same event. In my case, I am using an event at the end of the video to trigger the start of the next video in a list. However, since the event at the end of the video is triggered more than once, the "next" video would get triggered more than once.
This does not happen if using an MP4 file (like what is in the example project from the widget).
Steps to Reproduce
initState()of_BumbleBeeRemoteVideoStatewith the code sampleflutter runExpected results:
1 log entry of "Video Ended"
This is what happens if using a network .mp4
Actual results:
Multiple log entries of "Video Ended"
iOS - it is logged 9 times
Android - it is logged 2 times
The number of times also varies based on the HLS stream provided.
For example, in iOS:
