The operator '..' is not working in flutter - dart code

I am looking at the following video where they use the .. operator inside initState()

https://youtu.be/uz4xRnE-UIw?t=117

in my code it does not work!

here is my code:

 void initState() {
    super.initState();
    // select where the video is coming from  asset/file/network
    _videoPlayerController = VideoPlayerController.asset(asset); 
    ..setListener( ()=> setState(() {})); // error: expected an identifier
    ..setLooping(true);  // error: expected an identifier
    ..initialize();  // error: expected an identifier
  }

broken operator

You are using ; after each line, in order to use .. you don't need to use ; at the end of line, so try this:

void initState() {
    super.initState();
    // select where the video is coming from  asset/file/network
    _videoPlayerController = VideoPlayerController.asset(asset)
    ..setListener( ()=> setState(() {})) 
    ..setLooping(true)
    ..initialize();  
  }

I believe you have extra supply of ;

 void initState() {
    super.initState();
    // select where the video is coming from  asset/file/network
    _videoPlayerController = VideoPlayerController.asset(asset)
    ..setListener( ()=> setState(() {})); // error: expected an identifier
    ..setLooping(true);  // error: expected an identifier
    ..initialize();  // error: expected an identifier
  }
