dispose method

@override void dispose()

If you don't need a command any longer it is a good practise to dispose it to make sure all registered notification handlers are remove to prevent memory leaks

Implementation

@override
void dispose() {
  _commandResult.dispose();
  _canExecute.dispose();
  _isExecuting.dispose();
  _thrownExceptions.dispose();
  if (!(_futureCompleter?.isCompleted ?? true)) {
    _futureCompleter!.complete(null);
  }

  super.dispose();
}
