Question 1

What are streams and how are they controlled in flutter?

Answer 1

It is like a pipe with 2 ends only alowing to insert something to the stream and the data flows to the other end.

The pipe is called a Stream
To control the Stream, we usually use a StreamController
To insert something into the Stream, the StreamController exposes the “entrance”, called a StreamSink, accessible via the sink property
The way out of the Stream, is exposed by the StreamController via the stream property

Question 2

What can be conveyed by a Stream?

Answer 2

Everything and anything. From a value, an event, an object, a collection, a map, an error or even another Stream, any type of data may be conveyed by a Stream.

Question 3

What is a single-subscripton stream?

Answer 3

This type of Stream only allows a single listener during the whole lifetime of that Stream.
It is not possible to listen twice on such Stream, even after the first subscription has been canceled.
