I am trying to connect my youtube player with firestore database but i dont know, i want to know what is the conntroller for youtube video player

CodePudding user response：

I guess you can simply create a YoutubePlayerController and give it as paramenter

controller: YoutubePlayerController(_documentSnapshot["url"]),

For further information on the controller take a look at the docu.

CodePudding user response：

First of all, this error occurs because you're trying to call a property of the YoutubePlayerController class that should be a type of its parent but you're calling it in the type of string, I guess the error occurs on the below's part of your codes:

Text(_documentSnapshot["title"],style: TextStyle(color: Colors.blueAccent,fontStyle: FontStyle.italic,fontSize: 20,fontWeight: FontWeight.w300),),

because the Text() widget just accepts string data type you should convert the calls instance to string by adding the .toString() function at the end of the _documentSnapshot["title"] property just like the _documentSnapshot["title"].toString() it may fix your problem if not, something is wrong in your response, try to log it on the console to see what is the problem.
