Broadcast Streams operations

In this lesson, you will learn to convert a single subscription stream to a broadcast Stream by using the asBroadcastStream() method.

Single Subscription Stream:

//This will generate a stream and return a reference to it.
Stream<int> createNumberStream(int last) async* {
  for (int i = 1; i <= last; i++) {
    yield i; //to be able to send spaced out events
  }
}

Basic Operations

Let’s convert this single subscription Stream to a broadcast Stream using the asBroadcastStream() method and re-examine all properties again.

This time we do not need to create a fresh Stream for each operation. Broadcast Streams can have multiple subscribers or can be listened to multiple times.

All the basic operations are carried out on the same Stream.
