Single Subscription Stream Operations
Explore the use of single subscription streams in Dart by learning to apply stream methods such as where() for filtering, and understand core stream properties including first, last, length, and isEmpty. This lesson helps you handle asynchronous data events effectively in your Dart applications.
Single Subscription Stream Operations
In this lesson, you will learn the usage of a Stream’s methods and properties with the help of examples. We will be using the following sample stream to carry out these operations:
Sample Stream:
We will use the following Stream to demonstrate the upcoming examples of Stream operations.
This function creates a Stream of numbers from 1 to the last number passed into.
//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;
