body: <p>When should I dispose BLoC? </p>
  
  <p>Even in the official bloc <a href="https://github.com/filiph/state_experiments/tree/master/shared/lib/src/bloc" rel="noreferrer">example code</a>, it creates <code>dispose</code> methods for the BLoC class, but they never gets called.</p>
  
  <p>Thanks a lot.</p>
