Stop listen event not working with one event

[ghost]

Hello. I am having trouble stopping listening to the event. Specifically, I have a dialog, when opening the dialog (a statefull widget), in initState() I declare listening to the 'ABC' event. At the time of closing the dialog, specifically in dispose(), I off listening. When it first opens the dialog, it works smoothly. However, from the 2nd time on, I did not receive any messages from the event no matter what I registered to listen. Currently I have solved it temporarily by adding the code to remove eventName in _listeners at the end of off(...) function. I post to hope you find and have a fix for this case that is better than my way, because my way is only temporary and I don't know if my way has a bug or not. Thank you.

if (_listeners.containsKey(eventName)) {
      _listeners.remove(eventName);
    }
