How to Transform Dart Streams: A Basic Guide to Stream Operators

According to the Flutter documentation, streams provide an essential feature for handling asynchronous sequences of data.

It provides a way to handle and process a continuous flow of data, where each event can be asynchronously received and processed.

To use the streams to their full potential, we can use stream operators. These operators are the methods that allow us to transform, filter, process, and combine stream data efficiently.

In this article, let’s take a tour of some operators/methods that are available in the Stream class.
