Dart is a fully object-oriented, class-based, simple, and clean language. Google’s popular mobile framework, Flutter uses Dart language to implement high-quality native applications, so it’s recommended that you understand Flutter before beginning this course.

In this course, you will dive deep into Dart 2 language features while using interactive hands-on code playgrounds. This course will help you become confident with Dart extensions, enums, mixins, generics, libraries, asynchronous programming, class variables, callable classes, and generator functions.

By the end of this course, you will have a strong understanding of Dart principles, and you’ll be ready to start using this powerful language in your own projects.

# Broadcast Streams operations

In this lesson, you will learn to convert a single subscription stream to a broadcast Stream by using the [`asBroadcastStream()`](https://api.flutter.dev/flutter/dart-async/Stream/asBroadcastStream.html) 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.
