stream_ext 0.4.0


Build Status

This is a port of the Rx functions for working with Dart's Stream type, which already has the basic set of Rx APIs such as select and where.

This library adds the more 'exotic' Rx functions such as delay, buffer, scan, throttle, zip, merge, etc. to help make working with Dart's Stream type even easier!

Getting Started

To get up to speed with stream_ext:

  • have a look at the Getting Started document
  • the wiki also contains details (including marble diagrams) for each of the functions
  • the example directory also contains more useful/meaningful usages for each of the functions
