Flow analysis: Track additional assigned variables information. We now track the following additional information: - All local variable reads and read captures (previously we only tracked writes) - For any conditional expression (`?:`) or if-test, the variables written in the "then" branch - For any logical and expression (`&&`), the variables written in the right hand side of the expression Tracking this information will allow us to implement legacy type promotion as part of _fe_analyzer_shared, using the same API as flow anaylsis, which will in turn allow a lot of front end and analyzer code to be removed and simplified.

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.
See LICENSE and PATENT_GRANT.

Our API reference documentation is published at api.dart.dev, based on the stable release. (We also publish docs from our beta and dev channels, as well as from the primary development branch).
If you want to build Dart yourself, here is a guide to getting the source, preparing your machine to build the SDK, and building.
There are more documents on our wiki.
