async 1.9.0

Utility functions and classes related to the 'dart:async' library.

Contains utility classes in the style of dart:async to work with asynchronous computations.

Zipping streams

The StreamZip class can combine several streams of events into a single stream of tuples of events.

Results

The package introduces a Result class that can hold either a value or an error. It allows capturing an asynchronous computation which can give either a value or an error, into an asynchronous computation that always gives a Result value, where errors can be treated as data. It also allows releasing the Result back into an asynchronous computation.
