                child:  Container(
                  child: SingleChildScrollView(scrollDirection: Axis.vertical,

                      stream: FirebaseFirestore.instance.collection("videoList").snapshots(),
                      builder: (context,AsyncSnapshot<QuerySnapshot>streamSnapshot){
                        if(streamSnapshot.hasData){
                          return ListView.separated(

    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.

    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.
