Me too, did try catch temporarily

Where did you try catch @YouROK ? In your code? where?

I think they probably mean they're wrapping the .close() / .dispose() method of the controller in a try/catch

e.g.

@override
void dispose() {
  try {
    _controller.close();
  } catch(e) {
    print(e);
  }
}

nope, still get this error:
