dispose method
void
dispose()
If you don't need a command any longer it is a good practise to dispose it to make sure all stream subscriptions are cancelled to prevent memory leaks
Implementation
void dispose() {
_commandResultsSubject.close();
_isExecutingSubject.close();
_canExecuteSubject.close();
_thrownExceptionsSubject.close();
_resultsSubject.close();
}
