Extension Methods

One of the most useful features of RxDart is its extension methods, which allow us to extend the functionality of streams with custom operators. Extension methods are a way to add new methods to existing streams without modifying their source code.

Commonly used extension methods

RxDart provides a wide range of extension methods for working with streams. Here are some of the most commonly used ones.

The flatMap() method

The flatMap() method allows us to transform each item emitted by a source stream into a new stream and then flatten the emissions from those streams into a single stream.
