A Stream provides a way to receive a sequence of events . Each event is either a data event, also called an element of the stream, or an error event, which is a notification that something has failed. When a stream has emitted all its event, a single “done” event will notify the listener that the end has been reached.

A Future is defined exactly like a function in Dart, but instead of Void you use Future . If you want to return a value from Future, then you pass it a Type.
