To understand how bloc works, we need to know what are events and states.

• Events: events are an application’s inputs (like button_press to load images, text inputs, or any other user input that our app may hope to receive).

• States: States are simply the application’s state, which can be changed in response to the event received.

Bloc manages these events and states, i.e., it takes a stream of Events and transforms them into a stream of States as output.
