I'm using the youtube_player_flutter package to play youtube embedded videos. I'm facing problems with the package. I tried almost everything as per my understanding using init method, function to assign the controller, etc none works.
Issues
YoutubeController only take a single id and I have a list of URLs, so I assign the controller in the listview builder method with the videoId assigned as per the index. The issue is when the app launch it works fine, but if I hot reload or save the play button turns into infinite loading, if I hot reload again it stops and turns back to the play button. If I play the video, the player plays but it still shows the thumbnail. If hot reloaded, the thumbnail changes to the playing video. After the initial launch if I hot reload or save. It will always need a hot reload to change the state.
Using onEnd() property to reset the video to the initial state i.e video thumbnail with the play button. But using
onEnded: () {_ytController.reset(); }shows the infinite loading with the video thumbnail. PS. states change only after hot reload.When the video is playing I don't want to show the headline container so I'm using
_isPlayingbool to change the state. The value is changing but the container doesn't disappear even with thesetstate(). I think it needs to rebuild again.Metadata Title is not displayed but works when the controller is assigned in
init()

CodePudding user response：
Some comments before code)
- don't put this final _ytController = YoutubePlayerController... into builder - you recreate all controllers every time, when run setstate. You have to make some list of controllers for every video and fill it into init override
- reset to begin you should do with _ytController.seekTo command.
- save you isPlayng states into global list and check it into the builder
- I got Metadata title from contrller ONLY when concrete video is playing. So better way - load titles for your videos previously through usual http.get request (to something like such https://noembed.com/embed?url=https://www.youtube.com/watch?v=668nUCeBHyY)
