removeListener method
- ImageStreamListener listener
Stops listening for events from this stream's ImageStreamCompleter.
If listener
has been added multiple times, this removes the first
instance of the listener.
Implementation
void removeListener(ImageStreamListener listener) {
if (_completer != null) {
return _completer!.removeListener(listener);
}
assert(_listeners != null);
for (int i = 0; i < _listeners!.length; i += 1) {
if (_listeners![i] == listener) {
_listeners!.removeAt(i);
break;
}
}
}
