Reason for revert: b/244407576 Original change's description: > Make `addStream` events be delivered synchronously. > > The asynchronous stream controllers were forwarding stream events > from an `addStream` stream through the same path as user-added event, > which added an extra asynchronous delay that is unnecessary for forwarding existing events. > > Change-Id: I8edd1936d0d155d051d3cb8f7f82c577334d5f8e > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/256560 > Reviewed-by: Nate Bosch <nbosch@google.com> > Commit-Queue: Lasse Nielsen <lrn@google.com> # Not skipping CQ checks because original CL landed > 1 day ago.

Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
